Client Testimonials

When we started out, complete satisfaction was our mission. Now, it’s our company’s tradition.

I came across Cornerstone by suggestion. It was stated that Cornerstone is an honest company. They sent out Barry M, what a great individual! Very personable and honest and his experience shows. I feel comfortable with this second opinion, knowing I wasn't being taken advantage of. This is excellent customer service and I'm thankful I reached out to Cornerstone, furthermore that Barry was the electrician that was sent out. He added a little light to my darkness.

From everything with calling in, getting appointment and first visit from Cornerstone electrician Jerry was awesome!Very thorough in checking our problems, fixed some and Ordered parts on the rest. Coming back in two weeks to finish the job. Very nice and professional and like how he covered his shoes with shoe covers to protect our carpets/floors.Plus, they have coupons and discounts and in our opinion reasonable pricing. This is the way a company should be run!!

I found Cornerstone Pros on Yelp where I put out an inquiry. I heard from someone immediately and scheduled an appointment for the same day. They let me know 30 minutes ahead of their arrival. I was sent a text about the person who would be coming to my home including a picture. He arrived when he said he would. He assessed what needed to be done, gave me a quote (which was very reasonable) and quickly completed the job. He made some recommendations about what else needed to be done in the future, but wasn’t pushy and said he would send me an email with information and an estimate, which I received the same day. Robert communicated with me professionally and respectfully, explaining everything. I will definitely use Cornerstone Pros again.

Johnathan,at Cornerstone was polite, friendly and knowledgeable.I called on a Sunday and was scheduled for the very next day. He first placed a tarp over the work area and fixed our kitchen plumbing issue quickly.I needed something else looked at and he took the time to let us know what was needed. He went above and beyond with customer service.I would definitely use Jonathan and Cornerstone again.Service again!

When Mark got here he put on shoe protectors before entering the house. I was immediately impressed! He handed me his business card also, which I will keep. He was pleasant, careful, and professional. He did the repair quickly and to my satisfaction. You can tell he is a seasoned plumber and knows what he's doing. I would definitely recommend asking for him in the future. Thank you Mark for a job well done!!!

My wife and I have used this company 3x now. Water heater, water pump, treatment system. Good work, always passes inspection, and the tech goes above and beyond. Everyone does their best from the tech to the accounting department to get stuff scheduled and work with situations. I’ll be a customer again if I need something!

Dewayne was absolutely amazing! A wonderful and trustworthy soul, he repaired our plumbing leak in 15 minutes flat. If you are looking for a competent, professional, and friendly HVAC and Plumbing pro, look no further!

Albert M. did an awesome AC tune-up. He let me know what was happening when I asked and he took pictures to document the work. High customer service responsiveness that put me at ease. With sat down on the porch to cool off while the diagnostics was performing and everything worked out. I will get an estimate for the UV bulb replacement, but the original installer should have a warranty that I can check. I will consider the monthly maintenance fee because it covers a lot. I wish I could pay once a year instead of monthly, but it seems reasonable. I found Cornerstone in the monthly advertisement magazine. Thank you for a great experience.

Andrea Dort

22:03 31 Aug 23

We had to replace the hot and cold valves so our new washer can be hooked up; so My friend suggested Cornerstone I called they came out very professional , friendly and very reasonable. Their quote was $150 cheaper then the first company that came out. I would highly recommend this company first.

James Wynne

23:04 15 Aug 23

We purchased an AC unit from Cornerstone a few years ago and also have maintained their twice yearly service checks. We are very happy with the unit and the service however their new tech Albert is the reason I am writing this review. He was very knowledgeable very thorough and because of his thoroughness noticed our capacitor had low wattage and he replaced it under our free warranty thereby saving us from our AC going out in the near future! He was a pleasure to have in our house while he was here and I just wish all servicemen who came into our house were as thorough and respectful and kind as him. I will be requestingAlbert to always be our Tech so good job Cornerstone hiring good people.

Sandy South

19:10 04 Aug 23

I had a great experience with Cornerstone. The service technician was informative, friendly and helpful. Troy went above and beyond to take care of some additional issues I was having with my plumbing. I am a very satisfied customer and would recommend this company to others.

Michelle Macchiavello

18:02 01 Aug 23

WOW!Submitted an online appointment and Cornerstone called promptly the next morning. They were able to move up our appointment.Rob was very polite and genuine. Cornerstone’s system is very efficient in terms of sending a text as the appointment approaches. They send a photo of the tech with a quick bio. I was blown away how on point this company was. The parts / repair were MORE THAN fair. We are super excited and thankful for this awesome company. A+ service overall.Note: although they fixed our unit we are planning to work back with them for a change out in the near future. No doubt we will choose Cornerstone.

Jason Ballard

15:47 28 Jul 23

I heard a lot of great things about Corner Stone and today I got to experience firsthand the great customer service! Joseph who came to do a plumbing inspection was personable, clearly reviewed what he would be inspecting and made recommendation on preventative maintenance that I ended up getting for my tankless water heater. Thanks Joe for your professionalism and expertise! Also, the staff in office, communication and follow up was top notch! I would recommend the yearly plan it’s a great value! I look forward to my next inspection for AC!

Noldo Rodriguez

14:39 26 Jul 23

Joseph was very informative and helpful at help us understand each part of the diagnostic process on our water heater and he didn't leave until the job was done. Although it turned out to be an electronic issue with the disconnect box but it felt good to be reassured that everything else was in working order. He offered but didn't try in force us to use there company electricians who BTW he told us would be able to come out and fix our issue for two week. Luckily we have a family electrician so we were good but it felt none pushy so over all A+!

Cedric Street

00:54 21 Jul 23

I appreciate the quality of service from the phone call i made requesting the service to the service technician, Andrew, determining the problem and fixing it quickly. He even had to shop vac out water that had accumulated under some of the unit because the panel had blown off (we had just had rain). He was thorough and friendly. The company's cost was very reasonable. We very much appreciate a company that does not over charge even though they could ( I mean who wants to live without AC in Florida). Thanks Cornerstone!

Jewel Sapp

19:20 13 Jul 23

This company is fantastic! Very straightforward and they never tried to sell me something that I don’t need. My Technician Alvino was great! Very informative and I really appreciated how he got me involved in his work. It showed me that he was very trustworthy and very skilled at what he does. I highly recommend!

Aram Soriano

21:16 12 Jul 23

Look no further than Cornerstone Pros! They've mastered the secret to good business with good communication from start to finish.Top notch customer service provided by Ricardo who came out to handle my A/C warranty repair. Ricardo was friendly and professional - and took the time to explain what he was going to do every step of the way. When he was done he recapped with good pics of his work (all of which was emailed to me for my records). Thank you Ricardo and Cornerstone Pro's!

Tony Cabral

20:10 12 Jul 23

Donovan is very courteous and very professional. He came on time and very respectful of us and our property. He checked the water softener that’s leaking and recommended the best thing to do. Will def recommend this company. Thank you Donovan!UPDATE:Chris and Dave did a great job in the installation of our water softener. With an issue on the onset, Chris was patient enough to find a solution to this and he and Dave completed the job in no time. It was very well done, clean and precise. Chris went through explaining thoroughly how everything works. We are happy campers and will enjoy the clean and healthy water. Thank you Chris and Dave, Cornerstone Pros, D’Best!!

Sandra Santamaria

16:34 11 Jul 23

We have a clogged toilet they came out the same day. We noticed the water heater was leaking and the gentleman was kind enough to take a look at it. Turns out it was busted and we needed a new one. They were able to install a new tankless unit the next day. We even signed up for the monthly membership.Can’t wait to get plumbing, electric and AC all checked out. Had a great experience and everyone we met was amazing, kind and professional. Thank you so much!!

03:19 07 Jul 23

Our technician Zack was phenomenal. He responded quickly, even at off hours, rapidly diagnosed the issue with our AC unit and resolved it in a timely manner. All the way he explained the issues, the necessary fixes, and always made sure to not pressure us to agree to anything merely providing explanation. Superbly professional.

Michael

01:42 25 Jun 23

My technician, Andrew, was terrific! He was very courteous, friendly, professional, ethical, and had integrity which is what I was looking for. I just bought my home in Hudson, FL a couple of weeks ago and called out another a/c guy- who I wasn't at all impressed with- so after reviewing Cornerstone Pros, I decided to give them a call this morning when my a/c completely stopped working. I was thoroughly satisfied with Andrew and his expertise, and thanks to him, what started off to be a bad day...turned out to be a blessing! :)👍🏻Cornerstone Pros

Todd with Cornerstone Pros reached out to me when he was 15minutes out with a great heads up. Upon arrival Todd gave us a great overview of the tasks that were going to be completed and the service was done in great time. Todd also provided us with additional insight on ways to avoid clogging, how to soften the water and some help we needed with our dishwasher. We were very pleased with his services. Things were left better than he found it and we are very grateful for his assistance!

Called to have my ac serviced, they were very quick at getting service to me. Ronnie the tech was very polite and easy to talk with helped me understand more about my system. We also talked about family he was very easy to talk with. I would keep him in your business for ever. I’ll give him a 10 out of 10. I would recommend your company and Ronnie to other family members. Very pleased with everything.

James Hicks

00:53 15 Jun 23

Josh and James were the installation team. They were the best! Very respectful, responsible, and cleaned everything up. Really felt like we could trust them to handle the job and we were not disappointed. Travis, the salesman was so knowledgeable about the product and just very nice demeanor. All in all we felt comfortable with the whole team. Time will tell regarding the efficiency of the unit, but we sure were impressed with the employees. The new a/c I will say is so much quieter and cools very easily. 😁

Carol Hudge

22:08 19 May 23

Cornerstone is a highly professional company. They were attentive to my needs, friendly and knowledgeable. The repair was done quickly but done right. The Technician cleaned up the area and made the payment process easy. Would definitely recommend Cornerstone to friends and family without hesitation.

mike loucks

20:27 01 Mar 23

Nathan W did a great installation. In the last two weeks we have had Cornerstone Pros replace our entire a/c system, install a hybrid hot water heater, and now a garbage disposal. Everyone I have communicated with have been very helpful. You don’t find many companies like this. Next up, some electrical repairs.

David Bundschuh

22:19 15 Feb 23

We have had issues with our bonus room AC system for years! Even after Cornerstone installed a new system there were still humidity issues which lead to mold in our ceiling. Today they came out and corrected every issue and completed a very detailed installment. Thomas and David did an excellent job! Very thorough and detailed. We appreciate this so very much! A big thank you to Kevin and Brad and Brandi for following up with us on this issue and rectifying the problem. You have no idea how much we appreciate this service that you provided. ❤️

Dee Vallejo

19:57 06 Feb 23

We have been very pleased with Cornerstone ever since we bought our AC unit 8 years ago. Scott K came out to service our unit today and he went way above and beyond with his expertise, care, and attention to detail. Scott was extremely helpful and patient as he carefully explained the status of our unit. He even took the time to explain it all again to my husband on the phone. Scott took pictures of his work and showed me every step that he took in maintaining our unit. He made useful recommendations to keep the unit running smoothly. We are more than pleased with having Scott K work on our unit.

Technician Troy S. arrived at my home within two hours of my call. He was very pleasant and professional. The installation went smoothly; workmanship was picture-perfect. He even put my washer and dryer back in place. Very pleased with the service. I will definitely use their services in the future. And recommend Cornerstone to my neighbors.

Jeff Grigsby

17:50 02 Nov 22

We have used Cornerstone in the past and will continue to use them. All of their employees are highly professional and proficient. They do quality work and consult with you throughout the process. They are quite knowledgeable about their work and are detail oriented. For this particular job we had Gerald and Josh. They are experts in installing all of the electrical work we had them do. It was a 2 day job and they did it exceptionally well. Our home looks great!

Carol Smith

13:56 15 Oct 22

Sean from Cornerstone exceeded my expectations. He was very competent and identified the problem with my air conditioner unit in no time. Sean worked meticulously until he fixed the unit. He was personable and very informative. Sean showed me the work that he had completed and how to maintain the unit until he maintenance it again in 6 months. He informed me about the company’s 30 day guarantee policy on repairs. I wish I had found this company in 2020 when I replaced the unit. The prices are reasonable, the technicians are competent, and their customer service is phenomenal! I would recommend Sean and this company a thousand times.The moment I realized that Sean was really amazing and would go above and beyond is when he entered my home and heard the smoke detector chirping due to its low battery. He said, “That has to get on your nerves.” Next thing I know, he had his ladder taking the smoke detector down. I am so glad I found Sean and cornerstone!

It was very nice to have a highly trained ac professional. Travis B came here prepared and ready to work quickly diagnose the situation and made repair as quickly as possible. He definitely made my day cool and now my AC is running like it should. I would recommend this company to my friends and family or anybody. The office was very great Stephanie B did a really great job Schedule the call for our family and asking basic information for the service tech.I will definitely use this company again thanks again Cornerstone for making my day so much cooler.😎 Because it’s no fun sitting in the house that’s 90° in this Florida humid heat.

Kevin Gable

13:31 19 Aug 22

Mark came to assess my urgent situation. I've worked with him before from another company so it was really nice to see a familiar face. Mark was very helpful and provided multiple options in great detail.Robert's installation was done timely and neatly. He and his helper were very friendly and professional.I'm pleased with their service, knowledge and work! Thank you Mark and Robert!

Debbie Clark

16:27 16 Aug 22

Air conditioner went out on Friday. Mike came and replaced a part. On Tuesday it went out again. Mike was back the next morning.He explained to me that it would probably continue to break down, as it was an older unit. He gave me 3 different prices and options. To my amazement, he said he would go with the less expensive one as that would be fine for me. Any other company would try and sell you the more expensive one. I completely trust this company and Mike was great!

Linda Box

15:22 10 Aug 22

The two technicians worked quickly and efficiently; one removed and re-installed the outside compressor unit, while the other did the same with the inside air handler unit. They arrived in mid-morning and had the job completely finished by mid-afternoon. They left the area clean and free from any packing, shipping, or installation debris. These guys were knowledgeable about their equipment and well prepared for the job they had to do.

Gary Moss

16:49 09 Aug 22

This company has been around has a reputable name. And I know the owners. After calling multiple companies that all they did was electrical I called Cornerstone explained my issue and they put me on the books.The new tech Samuel was extremely patient knowledgeable and kind.Because my issue was more cosmetic they applied a discount code that saved me a ton of cash.Good company great responsive service and they are honest. Which seems like a dieing breed.We have substantial work projects coming up and Cornerstone will get all that work.10/10 will be further recommending them to friends and family

I've used cornerstone for my last couple houses and my mother's.. Overall we have a good experience. Today we actually had a warranty warranty AC service repair. The main thing I'd like to compliment is the technician Sean. My mother Whose house needed repair, was home at my house while her AC broke down. The parts were covered but of course the service call and labor were extra. But shut but Sean was very polite and professional.. And he had a very good demeanor with Customer which was me. Anyway I was pleased with his Service repair Of my mother's unit. My rating is specific to today's visit only but I thought he warranted A good rating

13:27 08 Jul 22

I love that the company sends out a text so you can track the arrival of your technician. Jeremiah and Giovanni arrived right on time. They were extremely knowledgeable and professional. Jeremiah explained everything in detail. Their prices were competitive AND the company offers a Veteran's discount. Our technicians were a dynamic duo. They were fast and efficient, cleaning everything up so it was spotless when they were done. Based on the professionalism of the company, the pricing, the knowledge and work ethics of both service technicians, Jeremiah and Giovanni, you can consider us customers for life. Please give both gentlemen a raise. They were AWESOME!!!

I was very upset when I had a handyman come and fix my water heater. However, it wasn't fixed. I called and I was able to get a great person name Kerry to come and advice me on what needed to happen. I needed a whole new water heater. He explained everything o me and gave me a quote.The next day Tony S. came out installed the water heater in a timely and professional manner. I love Cornerstone Pros! I would recommend there service to all my friends and family. I will also be in touch with all my other home repair issues...

Dreames Robinson

00:44 16 May 22

James was excellent! He’s thorough, polite and most importantly honest. This gentleman took his time problem solving and listening to our concerns. Then He walked us through the entire process. He gave us options and real expectations of the outcome. We were pleasantly surprised every step of the way.Once we decided on the options. He went right to work with the precision only experience can produce.I would not hesitate to recommend this company based on my experience with James and the office administrative team.Oh one more thing. We were originally scheduled for next Tuesday and they managed to give us next day service. Wow! Great people, great service and results.

I’ve used Cornerstone several times in different homes I’ve owned over the last 5 years. I’ve never had any issues with anything they’ve installed, but I did have an issue with workmanship on their tankless water heater and I’m not pleased with what I was told over the phone. I have over 17 years of experience installing equipment on people’s houses and would never do something that would pass an inspection but look like sloppy work. There is a balance between minimum code and neat work that should be maintained by any service technician in any trade. They missed it. My plumbing inspection failed because the drain pipe on the tankless heater was not strapped to the wall and was only 1/2 inch above the concrete floor of my garage. The inspector requested the pipe be at least 2 inches above the concrete and at minimum, the end of the pipe strapped to the wall. They did send a technician to fix the deficiencies, but instead of cutting out an inch from the existing pipe, he chose to completely replace the pipe and ran it down the center of a 3 foot wall in the garage. It came off the water heater at a 45 degree angle and dropped about 2 feet before it met the wall. (It was run down the corner before.) when I called to ask if it could be replaced the response I was given was “Well, it will pass inspection the way it is, but we’ll send someone to move it for you.” I have no complaints about the work done by the electricians. They showed more pride in their work than one of their plumbers. Only 4 stars for the attitude I got from their office. (I think his name was Nathan) Added a photo for reference. Blue line in the corner is the original path, red line is their “fix” for the inspection. It would fail again because the end of the pipe isn’t 2 inches above the floor, but the inspector isn’t coming back out.

So far I have dealt with Jason only about installing a new heat pump system! He was very helpful and knowledgeable. My new system will be installed Monday 3/8/21. Will rate the installers after they complete their work!Thomas and Juan did a great job installing my new Daikin heat pump system. Unfortunately. The outside compressor unit had a factory defect, but Gary, one their managers contacted me and made arrangements to install a new compressor within one day! I sincerely appreciated their quick replacement of the faulty unit! The new system is quiet and efficient. I recommend Cornerstone Pro for anyone contemplating replacing a heat pump system!March 14, 2022Sean came out today to perform annual Maintenance on my one year old heat pump System. He was on time, professional, technically competent. courteous, and respectful of my home and property. He got right to work and perform necessary Maintenance on my System! He explained the Maintenance he performed and made suggestions for to protect and extend the life of the system! Cornerstone has lived up to their reputation for good customer service!

Had plumbing inspection, very on point, knowledgeable Tech. Really prides on customer experience.After calling five other companies that offered emergency and weekend calls, Cornerstone was the only one that was available to take care of situation. The tech, Jeremiah was on point, knowledgeable, fast and professional. Truly what makes the difference between a quality company versus the others.

Carlos Rivera

18:22 03 Mar 22

Cornerstone Pros are the best. It is very difficult to find a business as professional as Cornerstone. My last service was for AC maintenance. I am a member of the Cornerstone Savings Club. The savings club is a great value. The employees are hard working and professional. Cornerstone Pros notify you in advance with scheduling and a photo of the technician. This is a first class business. Keep up the good work!

Eric Ashley

20:57 02 Mar 22

I called to have my HVAC maintenance done and was told I could have someone out the same day which was a plus. Matt came right on time and got to work. He is very professional, thorough and left everything as he found it. He gave us some great recommendations without being pushy like other companies. I highly recommend his services and the Cornerstone team. They are all very professional and courteous with their customers. I am a repeat customer and have always had great service.

Erika Rivera

15:08 16 Feb 22

Cornerstone is awesome. Our technician was Jeremiah and he was professional, knowledgeable, and most of all fixed the problem. Prices were reasonable, way better than I expected. He was really helpful with other services we needed and got us estimates for that as well. Cornerstone texts you with information pertaining to your visit as well. Nice touch. Will definitely use them again, in fact we have a second repair scheduled for the end of the week. Highly recommend.

I arranged to have a new water heater installed as well as a new water softener installed. I was having problems with my old water heater and my old water softener needed to be replaced and relocated.First, I believe that I got an outstanding price for both items (I received a Gold Club discount which I highly recommend). The technician (Austin W) and his assistant did an outstanding job in installing the water heater and did an outstanding job of relocating the plumbing for the water softener and installing the new water softener. I am extremely happy with the installation which was done to code and looks professionally done. I regret that I don't remember the name of Austin W's assistant.As a result of relocating the water softener, it was necessary to install a new power outlet. Manny G. was the electrician that showed up to install a new power outlet. He showed up midway through the installation and had the power outlet installed in time to test the system. He was a total professional and did an outstanding job.This was not the first time that I have used Cornerstone Pros. About a year and a half ago they replaced my air conditioning system which is still working without any issues.I highly recommend this company.

Timothy McDaniel

00:47 01 Feb 22

Absolutely the best service from Branden! He is the only tech who I am comfortable servicing my 28K heating system for Florida Power Yoga! He knows his business. Does whatever it takes to get the job done snd doesn’t leave until he is sure it’s complete and doing what it is supposed to do. I highly recommend Cornerstone! I love the the owner is a super sharp woman who knows heating, cooling and electrical. If it’s not 90F inside the Sweat Shack with 65% humidity my customers are not happy. Thank you Branden for making so many people happy.

Denice McClure

21:50 28 Dec 21

Their turnaround time is amazing! We had a new A/C installation and were having leaks. They sent Matt W over to take a look. Matt is by far the best technician at this company. He’s very knowledgeable, professional and knows exactly what he’s doing! You can definitely tell he takes pride in his work. Highly recommend him!!

Good people, had a new electrical panel put on, they were reasonably priced, I had 5 quotes for it. They were the most professional and almost the cheapest, but at the end of the day I thought their plan was the best. Would recommend for electrical work, and I'll think about then next time I need anything done.

Jerry was excellent. He called an hour prior to arriving to notify me of an approximate time he would arrive. I had multiple smart switches that needed to be installed. He was patient and went above and beyond than what I expected. He was very good at explaining what and why he was doing what he was doing. Very professional and it took a lot less time than I anticipated. We just bought this home and have several small jobs that need to be completed and we will definitely be using Cornerstone for these services.

I turned the heat on last night since it was going to be much cooler than usual. When I got up this morning, the house didn't seem very warm. Turned out that it wasn't. I had used Cornerstone Pros in the past for plumbing and was very happy with the service so I called them again. I was very happy to hear that a technician could come out today. Ronnie replaced a relay and the heat works beautifully. Ronnie was very professional and efficient. Cornerstone Pros are my go to professionals for all my plumbing, electrical and HVAC needs.

I was really impressed with the technician that we had come out today. He was courteous, intelligent and knew what he was doing. But the other thing that was really important was how comfortable it was to have him here. It's like my brother sent over his adult son who was knowledgeable, and capable to fix a problem he understood. We were just was really comfortable 😊 having him here. Quick fast efficient.

I continue to use Cornerstone Pros for my AC and Plumbing needs. My brothers an electrician so I have to go with family for that portion. I’m in the trades and what’s most valuable to me is work knowledge, professionalism, service after the work / will the person or company be around after the work is complete. Had a water pump that supplied water to the house leak, never dealt with one before. The company is very transparent about their pricing (you may not like it, but you know what it is) The technicians are very educational in explaining what needs to be done and what to expect. My most recent experience with Troy S was consistent with my prior experiences and nothing short of what I’ve come to expect. They clearly run a tight ship and I’ll pay the little extra for that all day and pass on the unlicensed person around the corner. I sleep very well not worrying about the work that was done.

Jerry came out to check all of the electrical outlets, electric panel and do some maintenance on our electric panel. We were interested in an estimate for additional electrical projects in our home. Jerry called when he was on his way and arrived on time. Cornerstone even sent a text message of his picture so we knew who we were expecting. Jerry was great. He was professional, knowledgeable, friendly, very helpful in explaining things and answering all of my questions. Looking forward to using Cornerstone in the near future for our electrical projects. We had Cornerstone out in the past to do our air conditioning repair and they will be out to do our seasonal service on our AC as well. Completely satisfied.

Matt W was extremely helpful, professional and knowledgeable. He took his time to evaluate and fix the issue I had with my new AC system that wasn't functioning properly and educate me briefly on how the system works and what to expect.Karen and Danielle were also very helpful trying their best to schedule my appointments as promptly and fast and I really felt like they cared to address the issue. Highly recommend this company without any reservations.

I am in the market for a new air conditioning system. Gary B. presented 4 proposals that were fully explained. He listened to my personal situation, needs, and developed a plan just me. I was amazed at the discounts and high quality service. The sales/transactions were totally done by phone and email with high quality attachments. He was very transparent and honest. I value these attributes.Thank you

Our sales tech Chris was excellent. He was professional, courteous, genuine, and respectful at all times. He provided multiple options, not just the ones that would net the most cash, and there was never any sales pressure. He was very patient as I considered my options and discussed them with my family. He was happy to show me specifically what the issues were, educate me about the solutions, provide timelines, and suggest interim comfort options. Cornerstone has always serviced our units before, and that will continue. Unfortunately, it’s time for a replacement, but I couldn’t have had a better experience than I did with Chris.

July 2021 - Still my go-to team. Called and got my water heater replaced so quick it was like a dream!2021 - Still top notch. Still incredibly helpful, honest, and dealing with real folks. They'll give you the good news, the bad news, and the way forward. I cannot stress enough how wonderful it is to have a long-standing relationship with a business that respects its customers. I recommend them to friends in the area, and some outside of the area are really jealous when I talk about your team!Mike came in today to fix some valves in my guest bathroom after a D-I-Y project ran into unexpected difficulty. He was professional, friendly, and fast - in and out in no time at all.2017 - Reese came over to get me a quote on a water softener. Very professional, knowledgeable and friendly. He let me know exactly what he was quoting me on and tested my water. Love this company.

Called early this morning and was originally informed a technician would be available tomorrow. However, they called me back about 2 hours later and was able to schedule a call for today.Air Conditioning was old and leaking freon. Robbie was professional, personable, and thorough. He walked me through the issue, provided me with multiple options, and helped me to understand the pros and cons. As a result, I felt I could make an informed decision. Problem will be fully resolved tomorrow. Very happy I went with this company,

Cornerstone Pros did the re-pipe for my block home (built in 1956) ... and I am very happy!They impressed me every step of the way ... starting with Scott who came out just one day after I called to request a quote, also with their excellent updates/follow-up, and especially with their hard-working plumbing team (Patrick, Robert and Eric). Everyone was very professional, knowledgeable and super friendly.Other than knowing it was going to be an expensive but necessary house update, I wasn't really sure what to expect ... thinking it was probably going to be a huge mess with lots of holes in the walls. I was amazed and pleasantly surprised ... not only were they budget-friendly, the work they did was so neat and clean that with most spots you would never know there had been a re-pipe done.I would definitely recommend Cornerstone Pros ... they did a great job!

00:50 25 Jun 21

Chris was extremely professional and did an incredible job explaining everything so that we understood what was wrong. He didn’t try to up sell up on anything or act like a salesman, he just gave us the facts and allowed us to make an informed decision. They came out same day I called and everyone I spoke with was kind and professional. I highly recommend them and will definitely use them again in the future.

From start to finish everything about this business exceeded my expectations. From the customer service reps who I was in contact with to the gentleman who came to my home for the service- Jeremiah was awesome! I had a clog in my line similar to what happened a month before during which I had another company come out on a weekday. I called that company and they were unable to come out on the weekend, so that prompted me to call Cornerstone. The previous company left an awful mess of toilet paper on my walkway and plants, and took multiple hours to complete the service. With Jeremiah, there was no mess and he had it fixed in an hour or so! He was so friendly and professional, certainly displaying that he is skilled in his trade! And for a weekend service, it cost less than the other guy! Safe to say I am impressed and extremely grateful to Jeremiah and his crew, and in the future will definitely be recommending my friends and family to Cornerstone.

I just moved here from Nashville and was not sure who to call...neighbors recommended Cornerstone. Jason arrived ON TIME!!! He was thorough and kept me advised as to his progress. He explained things in a professional and easy to understand manner. What a pleasure to work with someone like Jason.I felt so strongly about the visit, that I phoned the office to reinforce my extreme satisfaction.I want Jason as my lifetime service guy. Thanks for everything.David I

I called Cornerstone Pros on a Sunday evening after discovering water bubbling up from the ground on the side of my home. A technician promptly came out and quickly resolved the issue. Cameron really put our family at ease and even made some suggestions for things we could do to prolong the life of the pipes. Great service, and I would definitely recommend Cornerstone Pros.

Moreen Barker

23:29 25 Apr 21

Tim and Trevor we’re awesome! They traced the issue to a sensor wire in the compressor that had worn the insulation off due to age/vibration. I’m tech savvy with an electronics background but I don’t know A/C systems. Not only did they fix the issue but they explained what they were doing and why. I’d highly recommend them. This was my 3rd service call over the years on a 14 year old system and they have always done an excellent job! Five stars! Thanks!

Jerry G is as professional as they get. His respect and knowledge in electric is far advance I could not have expected more. I had a electric panel replace and it was a job and a half. It had to past code and there was very little room to give but not one but 2 agonizing hot days did he and his helper work to make sure it past inspection in which it did. I will always call this company for my service needs and hopefully they will be smart enough to keep Jerry on their payroll. I wish I remember the other man with Jerry because he also did a awesome job. they were a great team. Thanks cornerstone for renewing my faith in a complicated world. regards Mr Mike Williams

Today, I received a quote to do a replumb on my house. I will respond soon. Very impressed with Reece & Eric. Reece was very knowledgeable and answered all of my questions. I was amazed that they even put on shoe covers to enter my home. Very easy to talk to about their product. They did not make me feel like they were “dumbing it down” since l am a woman. Very thoughtful & considerate gentlemen.Thank you for your time.Charlotte

Ian, the technician was very helpful in explaining things that needed repair. He gave me clear details, showed me pictures and provided a clear readable report. This is my first time using Cornerstone Pros and I feel like I have finally found a company that I can depend on to be honest and do a quality job. I plan on using them for all my AC needs and signed up for their maintenance plan which seems like a great deal. I already love their commitment to customer service.

Brad Brown

00:11 11 Feb 21

Daniel did a great job. He was here for our maintenance check up. He was very thorough. I would recommend Daniel and Cornerstone Pros for your A/C needs.Scott came back the next day to put in the part that Daniel had ordered the prior day. Scott did a great job. Was very thorough and made sure everything was working before he left.

I have used many home improvement services including installing appliances. Cornerstone Pros are far above all others. The employees from the dispatcher to the technician were very professional and personal. I felt they understood my problem and wanted to help me. The technician was very knowledgeable and sincere in solving my problem. He didn’t leave my house without making sure I was satisfied with the repair. I consider Cornerstone Pros my new plumber, electrician, and A/C company. Job well done.

Jesus Lopez

Chris was the ultimate professional. He did the job the way it should be done. I am a platinum customer and have had many services done by Cornerstone.He did a more thorough job then any services I have every had. I wish everyone we deal with in the service industry was like Chris. Chris is a major asset to any business he works for. I am not going to say great job Cornerstone I am going to say great job Chris who represents his employer who ever it is with a friendly and professional attitude, but more then that he is not lazy and does the job right.

Paul Clark

15:12 16 Oct 20

I can't Express how truly grateful I am for the professional service Brian provided. He is very knowledgable and knew a leak had to be somewhere in my 4 year old system. He was able to find the leak and he facilitated in setting up appointment for repair. Also I am impressed with office in providing timely appointment. Will continue using Cornerstone Pros and would recommend to anyone.

Chris was not only very competent but was very helpful in answering any questions I had in explaining services and their benefits. I appreciate him coming out and would definitely recommend Cornerstone to other friends and family. Thanks Chris (Peter Gonzalez, Temple Terrace)

The company is reputable and the employees are courteous. Their technicians have varying levels of expertise with electronically sophisticated A/C units. If you get the right technician, you will be very satisfied. It is possible to be disappointed by repeat visits to address the same issues that would have been resolved by a more knowledgeable and skilled person. They do follow up to resolve issues and I have found them to be reasonable. There are potential complications due to inexperience and communication among some of the dispatchers, but they are very nice. Just a bit frustrating to work with when they move techs and schedules around without consulting their own system notes. A shout out to Brandon, their best A/C tech. He knows his stuff and genuinely cares about customer experience. He is the reason we continue to call Cornerstone! He is honest, competent, and respectful. Don't encounter too many people like that these days. We purchased a top of the line A/C system several years ago, and have had more than our share of difficulty with it, but so far Cornerstone has provided honest service. Not thrilled with the second refrigerant leak in 5 years, but they have a plan to find it and repair it. Hopefully, the 12/12 warranty will be honored and these service calls will not be our responsibility if the leak is in their warrantied equipment. Seems to be their policy to charge customers for locating problems, even if they turn out to be on warrantied equipment. Don't know if this is a Cornerstone policy, industry standard, or even legal in the state of Florida. Why the four stars? Because we paid for a platinum service plan, and Brandon has worked very hard to not only provide platinum service, but to advocate for customer satisfaction from dispatchers and managers. Very much appreciated that he doesn't complicate the challenges, but helps resolve them when some of the others aren't as helpful as they could be.

Absolutely the best company I have ever worked with, from sales to completion. The communications with their customers are second to none from the top to the bottom. Their friendly technicians, led by Josh and Jason went out of their way to make sure we were satisfied and to keep us informed during the progress of the project. Danielle, from the front office even called me midway through my whole-house generator installation to inquire if everything was OK and to ask if I needed anything. They truly value their customers.

15:52 12 Sep 20

The Cornerstone technician did a very thorough inspection and maintenance of our HVAC system. I was very satisfied with the work that was done. My one complaint is with the company's communication. After our last inspection, I scheduled this next inspection, as I normally do. The day arrived and I heard nothing from Cornerstone so I called them and found that they did not have the appointment on their schedule. So I rescheduled. Again I did not receive a call in the AM to give me a window of time to expect the technician. Therefore, I again had to call them to get the information. I recognize that business may have some challenges with scheduling due to COVID issues. However, that should not preclude timely communication with the customer.

had a leak under the kitchen sink over Labor Day weekend and staff was able to get someone out to look at it within a couple hours. the technician gave us options to repair/replace our faucet and we selected to replace the faucet. he was able to get the work scheduled and completed as soon as possible.many thanks.

John Reel

19:00 08 Sep 20

As usual the technicians with Cornerstone are efficient, knowledgeable, hard working and produce great results. Their communication to confirm the appointment, the technician calling before they leave to ensure i'm ready and then tracking the technicians in route through the app; is impressive. After four different visit for different service requests including a full AC change out, I would recommend Cornerstone as the best bar none.

Air conditioning, being a basic health need should be treated as such. And just like choosing a surgeon, GP, or dentist one wants only the best.Cornerstone is just that, the best!

Our AC went out today with a heat index near 100. Sean G came out and quickly diagnosed our problem and was extremely friendly and caring. We shared in great conversation while he made a temporary fix so we could have AC today and tonight until a more permanent fix could be scheduled. Sean is an asset to your company and his customers. Thanks Sean and many blessings to you.

Cornerstone Pros installed a whole house dehumidifier for us. There were some hick-ups, the initial thermostat didn't work and they had to order a new one. The service director called me, I do not recall her name, but she explained the situation and was extremely professional. When the part came in they called to set-up an installation appointment, again polite and professional. Another hick-up occurred during the replacement, the unit didn't seem to recognize when it was supposed to run. And I had some questions about the settings. Today Quenton (I hope I spelled his name correctly, because he was awesome) came out and got it all working in conjunction with the air handler as I had hoped. Then he took some time to explain the setup and showed me it was working and how the unit is programed. Quenton was very patient, professional, and did an excellent job. I really appreciate everyone's contributions at Cornerstone Pros. Thank you!

Josh & Manny came to do some electrical work for us as part of a bathroom remodel. They were very friendly and professional, told me exactly what to expect in terms of what they were doing and how much it would cost, and were very invested in making sure I got what I wanted in terms of style & color of the outlets and switches they were replacing. Was the best experience I have had with electrician services. Will definitely use Cornerstone again!

Cathy Armstrong

15:42 24 Aug 20

My AC was broken recently. Called cornerstone 8:30 and a receptionist answered and routed my call. I had a tech the day after at my request. I had to work the next day. He gave me an estimate and although I did not obtain other estimates, I felt this needed to be taken care of right away. My new system was installed the next day. Two days later i had a problem with it not cooling. A teach named Quinton trouble shooter for 5 hours to figure out the problem, and was relentless. He temporarily fixed the unit so i can have air. It needed some parts and a few days later Quinton came to replace the parts

Donna O'Lenick

20:52 21 Aug 20

The employees in the office are nice and book your appointments quickly. Like the text and email confirmations and reminders about upcoming service. The technicians have been knowledgeable and do a good job. They service our HVAC twice a year and we have them do our yearly plumbing and electrical inspections. We recently moved and decided to keep their maintenance plan for our new house. We had some electrical install and repair work done. The appointment was set in a timely manner and business was conducted professionally.

Jeremiah is an absolute asset to the company.

I have been working with Cornerstone company for just about two years. I have NEVER been dissatisfied with any of the plumbing electrical or air conditioning service they have provided.

15:27 22 Jul 20

I can't say enough positive about the technician that Cornerstone sends out for our regular plumbing checkups. This is the second time Mark has been out and his thoroughness, knowledge and demeanor are remarkable. He is able to explain plumbing in a way that is easy to understand. He points out opportunities for us to improve our existing plumbing without being pushy. He shares tips and tricks for making our existing plumbing perform at its best. He keeps meticulous notes and was able to pull up details about his last visit that explained an issue we were seeing now (6 months later). He arrived masked, gloved and wearing shoe covers. Thank you !Cornerstone could not send out a better representative.

Tristan Lockwood

14:08 17 Jul 20

From the first interaction to the last installment this company is PROFESSIONAL. I called over 20 competitors and received quotes, Some higher some lower, However Cornerstone is without a doubt "ABOVE THE REST" Thanks goes to all staff and owner. MILITARY friendly Also!! Stay safe and thanks again.

We have used Cornerstone for years, mostly to nurse our severely aging a/c system, but also for the occasional electric or plumbing need. I love the integrity, quality, and professionalism of this company. The night we starting hearing our outside a/c unit INSIDE my kitchen, we immediately called. Although it was nearly 10pm on a Thursday, we spoke live with a tech, assured her that this was not an emergency, but we would like someone to come out asap. First thing the next morning, Cornerstone followed up with me and set an appointment for that very afternoon (Friday). They sent me both an email and picture of our tech and appointment confirmation. Prior to arrival, they called as well to ensure our availability. Our tech, Chris, was knowledgeable and respectful as he diagnosed the problem and presented different alternative solutions. We decided not to pour more money into a dated, failing system, and took the plunge to replace it. Chris provided us with various options, answered our questions, and gave us space to consider while outlining the next steps we would take once making our decision. He was extremely polite and professional. We reviewed our options, researched the offered products and prices, and found their quality to be superior and the investment to be a more than fair price for the quality. We completed the documentation agreement with our choices and contacted Cornerstone Pros to make the appointment. They forwarded me through to Chris again who was able to get the new system installed the very next day, despite it being a weekend (Saturday). I received another appointment confirmation email with the name and picture of my installer, Josh. Josh and his co-worker arrived at my house first thing Saturday morning. With 2 people working, the estimated installation time was cut in half, ensuring that our system would be fully functional by early afternoon. Both technicians were polite, respectful, and informative, explaining how to navigate through our new system, as well as ensuring the county permits would be issued once the business week reopened (I received my permit on Tuesday, along with a phone call to confirm) and the steps we would take to walk through that process. Cornerstone Pros is a company you can trust. They are deeply vested in this community, and their care for their clientele is evident. We are so happy with their customer service, quality, work, and professionalism, and we highly recommend them to everyone we know. We will continue to support gratefully this business as they strive to ensure that home is a haven. Thank you, Cornerstone Pros!

Desiree Serrano

02:22 14 Jul 20

I was pleased with the estimate experience. Electrical technician answered all of my questions in a manner that I could understand. He provided two price quotes and explained the difference between the two. I had already obtained 3 estimates, so with this reasonable price quote, I was glad to schedule with Cornerstone for my upgrade to code. I will post a review of the panel upgrade after the work is completed. Everyone has been helpful and courteous. Thank you.

Robin Leigh

15:25 13 Jul 20

The tech arrived on time. He was well groomed and friendly. We were greeted pleasantly and he wearing a clean uniform. Our initial impression was one of "professionalism ". He then recapped the work he was about to begin and asked if we had questions. We did, he answered. Then he started the job. For the next hour or so he worked constantly. His task complete, he explained his work and asked if we had questions. We did not. Hiring skilled workers is always a tricky business. Sadly, "professional" and "responsive" are terms that apply all too infrequently. But happily, they are words that are easily used to describe the Cornerstone Pros. We have now used this company five times. They do not disappoint and we recommend them without reservation.

Jimmy Key

16:34 10 Jul 20

I had a wonderful experience with Cornerstone Pros. From the initial call about a new AC installation to the finished installation everything was great. Michael came to do the estimate and was great to work with and offered a very fair price. They were able to install 2 days after we agreed to do the work. TJ was one of 2 installers and they did a great job. TJ went over how the new equipment worked and walked us through every step. I can't recommend them enough from start to finish.

Michael Fisch

20:26 06 Jul 20

Our AC unit kept turning on and shutting off and would not run consistently. Had FOUR technicians from 3 other companies who gave us a range of "diagnoses" they claimed was the issue with estimates of upward of $1500. We contacted Cornerstone who sent us an angel named Quentin. He was courteous, professional, friendly and most importantly, he was able to properly diagnose the issue which turned out to be a simple fix. We simply had way too much coolant in our system (which was done by one of the previous technicians). Once Quentin released the excess coolant and got it to the acceptable level our AC ran like a charm. Thank you for sending Quentin to our rescue. After having to endure 90+ weather for almost a week with no AC, he was a Godsend. THANKS QUENTIN!! You rock!! 🙂

14:28 26 Jun 20

We recently had Alvino M. out to do some repairs to our A/C unit. He was extremely professional, efficient and maintained safety guidelines. The company charges fair rates and offers coupons to help you save money when possible! We will definitely be using in the future. Can’t thank Alvino enough! He was great!

Kiley Bryan

Met with Ronnie M this morning to discuss a leak in my AC system – not a cheap fix! It does help though, when the tech comes across as being informative, trustworthy and honest. Excellent representative for the company!

Jeff Baker

15:45 23 Jun 20

We have a rental house that the AC went out in June. Chris Jones was the technician sent out and he did an excellent job. He communicated with us what needed to be done, was very courteous and got the job done quickly. I highly recommend!

Keely Arrington

15:58 11 Jun 20

Great company! Excellent service from technician to office personnel. Mark arrived promptly, diagnosed the problem and set to work. He was efficient, courteous and went above and beyond what was expected. I used Cornerstone for a plumbing problem but will now expand to use there services for my AC and electrical needs. Thanks Cornerstone!!

Quick call back during a nationwide crisis. Scott was freaking awesome. He did everything so fast. Including going to pick up a gas water heater and coming back. What I liked the most was that right off the bat he didn't try to run any gimmicks. Great service!! Definitely would recommend this business.

Victor

23:54 28 Mar 20

We've had nothing but good experiences with Cornerstone. They've done a great job keeping our A/C system up and running. Ronnie did a thorough check of our system today and offered some helpful suggestions for keeping it running smoothly. Recommend without reservation.

20:44 05 Mar 20

Satisfied OCD customer. I first want to say that I like to do my research before I buy anything and I mean anything. I usually will google for a while to narrow things down and then I will make my decision. I called around and got a few quotes for an A/C unit. Mine was 14 years old. I chose Cornerstone because their unit has a 12 year parts warranty and an automatic 1 year warranty on labor. Cornerstone advised I needed an air return installed in the back hallway of my house because none was installed. Mind you the house was built in 2004. The 2 guys (Daniel and Larry) came out and installed my unit. They were top notch. I am nerdy and asked tons of questions. They answered every one without hesitation. I have to admit I have installed a unit myself in the past with the help of a friend. We were not experts buy any means but the unit worked. After asking a bunch questions to these guys, I clearly didn't know enough to properly install that unit. These guys take so many steps to ensure the unit is installed and tweaked so that it runs perfectly.Cornerstone sells many brands and I chose the Daikin. It has a 12 year warranty and is a Japanese brand. Think of Honda and Toyota when you think of Daikin. I got a 16 SEER Heat Pump. a big step up from the 12 SEER that I was replacing.By the way I had them install a unit at my parents as well. They are as happy as I am.Bottom line is do your homework. Google stuff, ask questions, and be curious. Its a big investment. And give Cornerstone a try, I'm sure they will make you happy like my parents and I.

I had a great experience using Cornerstone Pros.. The plumbing technician, Jeremiah R., that came out to work on my washer drain did an awesome job.. He was very efficient in his work.. He was knowledge and informative as well.. I really appreciated him coming out to service the drain and resolve the problem so that I can get back to one of my many stay at home mom tasks, laundry! Lol!! Thank you Jeremiah and thank you Cornerstone Pros for being amazing! My family is extremely appreciative and happy to have clean clothes again, thanks to you guys.. 😉🙌🏼😄👍🏼

Awoke to a Super Bowl Sunday nightmare. Clogged master bath toilet backing up into shower. 1st experience with Cornerstone Pros could not have gone better. Called them and was reassured they would help. Was given an appointment time (no huge window of time). Then followed by a text and email confirming appointment and introduction email with a picture of Carlos my tech.Carlos was incredible. He listened to me about what was happening and quickly reviewed the plumbing issue. He provided me with my options and went to work. I am so impressed with your company and especially Carlos. If all your staff us as good as him.... then BRAVO

I have been a customer of Cornerstone Pros for about 10 years. They have consistently provided excellent service and support. Ronnie was the technician for my most recent preventative maintenance a/c service. He did an outstanding job. He pointed out and explained in detail a few issues that I will need to address. Ronnie was professional, knowledgeable, helpful, took the time to explain things in detail and answer all of our questions. Ronnie was real pleasure to work with. I can highly recommend Cornerstone Pros.

Today I had the BEST Experience with Cornerstone - Air Conditioning!! They were on time, very professional and delivered excellent service. I would recommend them to everyone. I am so happy that I called them. I don't think I will ever use another company!! Such a wonderful experience!!!

I called Cornerstone to remove an old tube and tile wall surrounding around it. After that they installed a new Jacuzzi tube. They were prominent and professional. I would use them again. Job well done. They did a great job. My wife and I are very happy with it.

Richard Hildebrandt

20:02 06 Jan 20

Josh and Ryan were very professional in explaining technical details of our air conditioner following the service to the unit. They were punctual to the scheduled appointment and were courteous and friendly. We appreciate the service provided by Cornerstone Pros.

I highly recommend getting the a/c plumbing and electrical package with cornerstone. They came and fixed a few problems we thought were big problems but were minor for nothing with the package. They gave very reasonable estimates on fixing a few things that we need fixed but didn't push getting them done just let us know what the problem was and what can be done to fix it if and when we want. They are extremely reliable and friendly. We are so glad we went with cornerstone when our hot water heater went out and got the package. Also the plumbers and electrician all came at the same time for our six month inspection so we didn't have multiple appointments to be home for they said which was greatly appreciated. We will renew our package when it expires it's so worth the very reasonable cost to have everything serviced and checked.We are so happy that a few of our house issues were not a big problem easy fixes that we would have never known about had they not showed us the problem and solutions. We will use cornerstone for all our a/c plumbing and electrical needs for sure. So I strongly recommend getting the service package it's worth it

Super impressed. Not only did they squeeze me in at the last minute but sent me updates letting me know when the tech would arrive. They sent a photo of the technician so I knew who to look for. Our tech was knowledgeable, honest, and quick to fix the issue. He rcommended upkeep for our unit. Great service all around. Would definitely recommend!

Heather Tressler

21:40 30 Dec 19

Reese arrived not long after I called the company. He was great! He is very professional & fixed the issue immediately. He gave a quote for a new water heater that was fair. I'm grateful for his honesty and friendliness. Definitely recommend Cornerstone. ☺️👍

22:19 26 Dec 19

Great company. Always on time, responsive and knowledgeable.Josh just serviced our unit, he called before he arrived, sent his pic as well so I knew it was him when he arrived, and he explained what he found and did. Highly recommend recommend this company!

Sheryl Springer

16:05 12 Dec 19

Second time calling Cornerstone in emergency. Last time, we really liked the technician they sent out(Ronnie), but this time we got Rob W. Service was just as solid and fast, he was extremely friendly and had us up and running in no time. He gave us a few options and some honest insight on each, with no pressure to upsell or convince us we needed the most expensive thing. We really appreciate the honesty and friendliness!

Sean Marcus

00:11 09 Dec 19

This company is amazing. My AC went out and I had Rob at my door within an hour and it was late on Halloween night. Rob assess the situation and while he said he could fix it, it would be stepping over a dollar to save a penny. LOL. I agreed as the unit was old. Rob was able to have financing in place on the spot and lined us up for a total refit in the morning. At 7 am Daniel and Jason were at my door and hit the ground running. It was like an Army hitting the beach. They had I believe Jason run in as well. This company did a late night service and TOTALLY new system in place well under 24 hours. This is not my first Rodeo and had service with other companies that took a day to even look at it then days to fix. I would highly recommend these men and Cornerstone to anyone. Very impressive. My neighbor will be calling soon. He was impressed as well.

Steve Chowning

20:54 01 Nov 19

I like that they send pictures of technician that will be coming to your house. This was the second time Josh has been here to check the AC. If you can request a tech request Josh. You will not be disappointed. He is very professional, easy to talk to and tells you everything he is doing. You can tell he likes his job!

Tina Sanchez

15:16 10 Oct 19

Very pleased with Mark S who installed my water softener and carbon filter system. Cornerstone did an excellent job giving me my options and quotes. They did not push or try to make me choose as their people do not work off of commission. Mark installed it, gave me all the details of what he did and answered additional questions that I had. Very pleased! Will likely use them again.

Andy Whitten

12:37 09 Oct 19

I hired Cornerstone to repipe a entire 1968 house that I was having renovated. I also had them install the shower pan and water heater. I cannot say enough good things about them. Friendliness price and quality of service exceeded my expectations. They very dependable and showed up when they said which was not case the other contractors that I hired.

Donna Rupert

20:49 29 Sep 19

Brandon did a fantastic job clearing out our clogged AC drain. I have lived in FL my entire life and have had many experiences with AC techs and Brandon was by far the best. He did a thorough job making sure the unit was clear, not just the drain line going outside. I was very impressed!

Tammy Moore

16:52 25 Sep 19

Gary was polite, courteous and listened. He did get a part of my electrical problem working. He has given me a quote. He appeared to be efficient and experienced. We serve the same God. That"s nice.9/18/19Jerry is the electrician who waited patiently with me today for the county to inspect and the electric company to turn the power back on. Very nice man and he seemed to know what he was doing. The county passed the inspection and Withlachoochee Electric turned the power back on. I am pleased.

Lil Collier

22:57 19 Sep 19

I don't normally comment unless the experience is very good or bad. In this case every aspect was amazing; from the wonderful customer service when I first reached out at nearly midnight to the technician that arrived first thing the very next morning. His professionalism and ability to explain not only the issue but the options available to me were comforting. I can't say I've ever experienced that level of transparency and it put me quite at ease. I will never hesitate to call Cornerstone or recommend to a friend in the future.

Pete T came over this morning and helped me pick out and install a generator breaker box in my garage. He was professional, courteous and knowledgeable. He did the job and made the new breaker box look like it belongs there. Thank you so much Pete!!

20:17 28 Aug 19

Excellent customer service. This company in the owner Dana were fabulous. They responded to my concern, quickly addressed my need, And scheduled an appointment so that my AC could be completely replaced soon. The value and quality work are exceptional. The 5th star is because cornerstone is the 1st company in more than 3 years that has arrived earlier or on time to an appointment schedule agreed upon. Thank you Dana, Travis and partner

17:10 25 Aug 19

Our maintenance contract includes two routine maintenance visits per year. The technician, Kyle, arrived on time today and was courteous and considerate while he was here. He did a thorough job of dismantling and cleaning out our AC system, taking before and after photos to show us what had been done. He cleaned our filters, too. When he left, our AC ran so much quieter than it had been running. We are glad we signed up for their maintenance program.

Mary Eisenacher

22:54 23 Aug 19

Jeremiah R. showed up on time and performed the necessary repairs and installations in a skillful and professional manner. He was friendly, provided helpful advice, finished his work quickly and efficiently. No mess, no problems. He will need to return in a few days to install a new replacement shower head and control set as these are not standard equipment on the truck. I was very impressed by Jeremiah and will definitely request him for all future plumbing needs.

Ted von Eiff

17:10 22 Aug 19

Cornerstone Pros are amazing! I needed AC, plumbing and electrical work done and they coordinated it so they all came the same day! They were all very professional and excellent communication. It's great how the office calls to verify the time and send you an email and text with the technicians info and photo ID.

Cara B

16:17 21 Aug 19

Cornerstone was fabulous! Here fast to replace our 2 ancient a/c units all in one day! We were dying here with no a/c in the middle of August! Efficient, provided great service with a 12 year warranty, thank all of you so much!❤

Christina Baker

14:48 19 Aug 19

This is the second time I've had Josh from Cornerstone provide a tune up and inspection service on my ac units. Before I moved out of my old house and now at my new house. He does a very thorough job and is really professional. I don't get the feeling that he's trying to sell me something I don't need. He seems very knowledgeable and offers solid advice and information.

12:18 13 Aug 19

One of our units just quit and the other was working on and off - with record high temperatures outside, of course! The response when I called was prompt, friendly and helpful. The technician, Rob, came on time and was very professional, knowledgeable and friendly. He kept us well informed from beginning to end of service and answered all our questions. We plan to ask for Rob for our twice yearly maintenance which was very reasonable. I'm glad I called Cornerstone!

Susanne J. Perla

23:29 01 Aug 19

Matt was incredibly helpful when our AC unit was acting up (in this July heat, yikes!) and was able to work quickly, after hours, to diagnose the issue and make recommendations. We were very comfortable with him and trusted his expertise. Definitely ask for Matt!

Although I have used Cornerstone for our air conditioning , ( Been thrilled with the service), this was the first time I used them for Electrical work. From the moment Jerry our service tech walked in the door he was polite profession and very knowledgable. He took the time to explain what he was doing and answered all my question. It was a hot day and Jerry had to work outside as well as inside and some how he stayed positive. Once again Cornerstone provides quality service.! I will be using them again!

21:57 16 Jul 19

Josh S was here today for one of our yearly AC maintenance visits and he was fantastic. He took the time to look over everything and really assured us that we are doing the right thing by having a membership with cornerstone. Thank you for keeping our units running at their full potential! Would highly recommend Josh S and cornerstone to my friends and family!

Michael Heatherly

20:09 06 Jul 19

Bradon was my technician. He called to let me know he was on his way to my house. He was so polite when he arrived, and got right to work. He worked, and completed his work. He did a great job! He told me everything I needed to do to make my air conditioner more efficient. He was not pushy at all. I want Brandon to come for all of my air conditioner needs.

Way to GO JAY!!!!Been dealing with Cornerstone for years. I have three houses in Plantation Palms that they service for me. They used to service my old A/C units and then they gave me a great deal and I replaced all three units. I just had a problem with one unit not cooling. It was in a house that I have a tenant in with small children. The part was not going to be available for about 5 days. Jay, the A/C Service Manager helped me out big time. He was leaving for the day so he told me he would pick up two window air conditioners and personally install them for my tenant, all on his way home!That's what I call going over and above to help a customer.Thank you Jay! Really appreciated your outstanding effort.

John Renda

19:17 03 Jul 19

I have found Cornerstone to be the most honest, professional service for air conditioning in Florida. All workers are very friendly and more than willing to answer questions and go out of their way to help. I have a maintenance agreement with them which keeps the units running properly and provides other discounts. I had Michael Morrow out today and he did a great job detecting a minor problem which was preventing cooling lower than 79 degrees.

J Wild

17:52 28 Jun 19

Josh S and Jon S came to my home today for routine maintenance on my A/C and to clean the dryer vent. What a GREAT experience. I wasn’t pushed to do anything extra and very laid back. I really appreciate that quality of service and their professionalism. Great staff!

Christina Whitten

00:19 21 Jun 19

My A/C started blowing warm air and the fan on the unit was not turning. Got very hot, very quick in my house. I called Cornerstone because a few weeks ago they put an entire new unit in my sons house and did a great job. I called them and Michael showed up in a reasonable time. He was so professional, friendly and most of all, honest! The only thing I needed was a new capacitor. He checked the entire unit including freon level and air handler. Everything was fine. And I have a very old A/C unit. I was expecting to hear really bad news. I only had to pay $311 total! My A/C is working better than before. Will call again with any A/C needs. Thank you Michael and Cornerstone.

Hi my experience on first visit from technitian Reese, was very pleasant, I feel great with his knowledge and aptitude, very humble person.I hope I can work with him and Cornerstone in the near future.Every person I spoke to at Cornerstone was courteous and responsive.I will wait until they can work on the price for the amount of work that has to be done in my house.Meantime the communication is great.I will recommend them based on the communication which is very important to me.

I am a relatively new customer, but more important, I am a satisfied one. Every family needs a good electrician, plumber, and AC service technician, and Cornerstone employs them all. It really is a comfort to know who to call when these types of services are needed.Most recently Gary was the electrician who installed a new panel box at the power pole. No more tripped breakers—such a relief! He was extremely knowledgeable and took the time to explain what I needed to know as the homeowner.I chose to join their plan which offers discounts to its members. It was a good decision.

Florence Jensen

02:54 12 Jun 19

I have used Cornerstone Pros a few times now. Their pricing is fair, they are always on time, but most importantly, their technicians are very knowledgeable. I have had a plumber, electrician, and AC tech come to my home and all of their work has been done quickly and professionally. The issues they fixed have not occurred again. With their membership you even save money in the long run. Mine has paid for itself.

Kenneth Lee

21:05 08 Jun 19

James G arrived a few hours after our ac went out last night. He is courteous, knowledgeable, professional, friendly and explains the problem and resolutions clearly as he goes along. It was late at night, and his energy and pleasant personality was refreshing. He knew immediately what the issue was, a drainage problem, and had our ac up and running in 15 minutes. He is efficient, a pleasure to deal with and we fully trust him to work on our ac anytime. I hope we see him for our next service call. 25+ years in the business and it certainly shows......he takes pride in this work and is a true gentleman. Thanks so much James G!

James G from Cornerstone Pros did a great job in resetting our air. He wasvery professional with 25 yrs experience. The problem was an auto shut-offfloat that shut the unit down. We have a new 5 ton unit, works great, can hardly hear the unit run. HAPPY WITH CORNERSTONE & JAMES G.

Greg Kornacki

13:47 05 Jun 19

I needed a faucet replaced in a property I owned. Danny N came and did a thorough professional job after he himself had had quite a long day. He's a really good guy and Cornerstone is fortunate to have him representing them in the field. I would recommend Cornerstone for any repair needs.Thanks,

Mark Kirkland

12:17 16 May 19

Good, Honest but can be be costly like any air Co in Florida. They know what their doing, very knowledgeable and the price reflects it. But I believe its worth it. Joined the savings club, so maintenance is scheduled and discounts on cost helps in emergency situations.I trust the reps they send out since Ive met them more than once, good retention at this Co is comforting. Its now a rental property so Im okay with contracting with a Co that diesnt take advantage and does a Great job handling any air issue! I appreciate you Cornerstone & Ronnie is the Best👍Phenomenal experience. Serviced our first home with a/c work, and plumbing over the years. Turned it into a rental and they've been keeping up the maintenance for the past two years. All the staff I've encountered has been knowledgeable and courteous. Always give fair pricing and discounts to club members/ long term clients. Never had to question or worry about the quality of work and we live in another state away from the property. Professional, timely, work done right the first time around. Listed as my vendor with our property management company. Nope their not cheap but neither is their quality of work/ service. You get what you pay for! Extremely trustworthy and Highly recommended.

Fantastic experience - everyone I spoke to was extremely nice and professional (Reese, Jerry, Carlos, Doug, office staff). They rearranged their schedule based on my emergency (water heater burst) and showed up exactly when they said they would. All the work was done professionally and at a fair price. Cornerstone is my new “go to” for all my electric/plumbing needs.

11:38 05 May 19

Had two technicians the same day and both were FANTASTIC!!! Thorough, clean, friendly and didn't try to sell me something I didn't need or want. I am a customer for life.Update....James Gordon came out and he knows his stuff. An inspection of my home stated the air handler was vibrating. After literally 1 second of listening to it run, James knew something was up. Luckily it was a simple piece of insulation, but James knew his stuff. Thanks again!!!

Kevin Staninger

17:59 03 May 19

On time, very knowledgeable and friendly. Gave me good tips on keeping my a/c running in top condition. These folks installed my new a/c and water heater about 3 years ago and the follow-on service has been great. In an emergency that occurred at midnight last year, they were there early the next day to fix it. Highly recommend.

Michael came out for a spring tune up. He was extremely professional and friendly. I can’t say enough good things about his patience to explain things and his willingness to help out. Just a 5 star experience all around. This is the kind of service that will change the industry!

Andrew Saadeh

19:58 26 Apr 19

We have used Cornerstone since we purchased our home a few years ago. They have been nothing but amazing to us!! They always do their best to get you a same day appointment and the techs are super friendly and explain everything well. Ronnie M was our most recent tech. Upon arriving at my house, he explained the issue immediately and offered a final solution so I should not experience the same issues any more. I’ll be a cornerstone customer for life!

Christina Grimaldi

16:11 16 Apr 19

Rob came out today for routine maintenance on my AC unit. I just purchased my house, and had a lot of questions. He was amazing! I unfortunately had some unknown issues with my ac unit, but I am so glad to know that Rob and Cornerstone are upfront and honest, a rare trait these days. I got the gold plan to check my electric and plumbing too. Way better (and less expensive) than my home buyers inspection! Thank you Rob!

Kristen Swanson

02:10 06 Apr 19

Daniel N and JP were very professional and kept us informed throughout the installation. The team notified us prior to arriving and arrived at the time promised. They provided us with all of the information that we needed to confidently operate our new A/C system which has a sophisticated control system with many features that we can use to manage our comfort and electric bill. After the job was completed, they cleaned up everything. You would have never known that they were there except for the new A/C. I would recommend Cornerstone Pros to anyone with an A/C need whether it be maintaining an existing system or installing an new system.

Greg Sandoe

13:14 29 Mar 19

I wanted to give a big thank you to Pete and Chris for helping me get my outlet installed outside for my car charger. They both showed up on time, Chris even showed up a little early. You can actually track their truck to see how long it will be before they are at your house, which is pretty cool, as I haven't seen that from any other company. They were very professional and did a great job with the location of the outlet too.

Regina Turgeon

03:23 14 Mar 19

Incredibly prompt in providing a very competitive estimate. Everyone that I've been in contact with has been delightful. Rob was very personable, honest and knowledgeable. Angie, very polite, responsive and professional. Kudos to Cornerstone for having an engaging hold message, I learned of their plumbing and electrical services through this avenue. We've scheduled our plumbing visit for Tuesday! Will be making AC decision by Monday!

Susan Black

20:17 21 Feb 19

Angie on the phone and Gary Capes the repairman BOTH did an outstanding job.Angie called in advance to explain details. She was super polite & clear.Gary was on time, explained what he was doing, gave me options, answered all questions and did a terrific job. He has 30+ years in plumbing & knew all the answers. My toilet works like a charm. In addition, he was kind enough to attach the chain to the flapper which had come unattached in my other toilet.I will be using Gary always in the future!

Carita Wells

15:03 30 Jan 19

It was wonderful and great experience with your service team. There were very knowledgeable and professional.I feel having such great high skilled services staff is great asset to the Cornerstone Pros.Denial and JP were truly amazing and great Team work. Everything was very smooth and well organized. Thanks for Morgan.It was an overall amazing experience.Keep up the good work!Thanks,

Called late on a Tuesday and received a Wednesday morning appointment. Rob, the tech who arrived, was very polite and professional. He put on shoe coverings as he entered my home to prevent dragging in dirt on his shoes. He was able to setup my new smart thermostat to have it work its best with my AC heat pump system. He also did a thorough system check and confirmed it was all up to par. I would recommend Cornerstone Pros for all of your heating and cooling needs.

Bob Sadler

20:07 23 Jan 19

Everything went perfect from start to completion with the service and repairs needed. I was able to obtain an appointment quickly, the technician (James G.) was here right on time and explained the whole process and what the problem was. My heating repairs were done about a month ago , but I wanted to wait until I needed to use the heat again several times to test it. Well, it is 37 degrees outside in Tampa right now, but my heating system is working perfectly inside. Thank you James G. and Cornerstone for the quick and efficient and professional service and I will surely call you again the next time I need your expertise.

Steve C

10:36 17 Jan 19

We had a leak somewhere in our kitchen...the cement between our tiles were damp. We thought that maybe it was the waste line. I called Cornerstone and spoke to Angie who was incredibly friendly and scheduled us for the following day (today) between 8am and 12noon. Danny and Mark showed up at 9am and found the leak right away, not at all where we thought it was. It was a cold water line leak which Danny showed to us. We didn't even realize how soft the sheet rock was. He cut a small neat square right where the leak was and repaired it. And while they were here we had them replace our broken garbage disposal. They were knowledgeable and professional. This company never disappoints...Thank you Cornerstone and thank you Danny and Mark for your friendly expertise. Reasonably priced too!

Josh was very thorough in his service for the ac unit.He explained what he did and gave recommendations from the numbers he obtained according to the input the unit was giving. His manner was courteous, professional and he exuded confidence in his job. Very satisfied with his service and the company itself.Gary has a very professional demeanor. He was very methodical in his inspection of the plumbing. He provided estimates for the future. Very well pleased with his service.Rory inspected all the electrical outlets including the electrical panel. He was very meticulous as he went throughout the whole house. He went the extra mile to figure out why one of the outlet was not working and fixed it right then and there. He conducted himself in a professional manner. Overall I am very pleased and satisfied with the 3 technician that came to my house. Will keep using Cornerstone . They are a very professional company.

Ivelisse Hulbert

21:53 02 Jan 19

Awesome company! Called in a panic after another company was a no show and they sent a tech out the next day. Kevin was on time, courteous and explained everything fully. He was even super friendly to my two year old and completely understanding when my dogs wouldn't stop barking. He emailed me a detailed receipt (including pictures of the work) just an hour after completing it. The price was higher compared to other places I called, but I'd gladly pay more to receive such awesome customer service.

Elizabeth Flannery

16:49 20 Dec 18

I just had a service call because my compressor would not start even though the air handler was running fine. Brandon, the service technician, arrived exactly on time and performed a quick diagnosis and fix. The best part was the detailed explanation that he took the time to explain why the system worked the way it did. I'm now a more educated and satisfied customer.

Wayne Coe

22:28 12 Dec 18

As first-time homeowners it can be very scary trusting professionals with home improvement. James was very patient in assisting us and knowledgeable in product specials. We are confident this is the start to a wonderful business relationship, thank you! We had a great experience working with Cornerstone

Cornerstone Pros contacted me to set up appointments for my periodic inspections of A/C, plumbing, and electrical items. Their employees are all very knowledgeable, helpful, and respectful. Martin walked me through the various options to renewing my level of services provided. I have always had great service from Cornerstone and recommend them very highly.

Sheila Sumaylo

14:19 15 Nov 18

My field service, Josh S., did a super job explaining the details of what he would be doing for my A/C inspection. Josh was quick and did a super job! He even gave me advise on when I should be changes my filters!Hannah G., scheduled my service and kept me informed on all the need information. Thanks Josh and Hannah for making my experience with CORNERSTONE a GREAT ONE!

16:15 09 Nov 18

I originally called Ierna AC and received a quote from them. Cornerstone was more expensive, but they were willing to price match. Matt from Cornerstone was extremely nice and was willing to just sit down and talk for the longest time! He was a very happy guy and knew what he was talking about. His personality won me over, and so we decided to pursue Cornerstone for a new AC unit.During the day of install on 11/7/18, Travis and Josh recently came and installed a new AC Unit, and all the bells and whistles 🙂 They were professional and courteous, and extremely helpful. Highly recommended 🙂 Hope you have a wonderful day and thank you for reading :)God bless,-James Doyle

Cornerstone Pros did an amazing job re-piping our home. They came in with a plan, walked me through step by step to make sure i was okay with all that had to be done. Danny (My technician) was extremely polite, and answered all questions and concerns i had. They were in and out in three days. Danny made sure to test everything for me, and make sure i was satisfied. He even cleaned up, and vacuumed the kitchen and bathrooms once the job was complete. I would recommend this company to anyone needing plumbing assistance.

As a new homeowner (just past warranty period), I was feeling a bit overwhelmed when I heard a drip coming from underneath my bathroom sink in the middle of the night. A Google search for plumbers in my area gave me a list that included Cornerstone. I'd seen their vehicles on the road and figured they were at least worth a call. I was pleased with (and relieved by) their promptness, professionalism, and courtesy from start to finish. Although I don't want any more plumbing problems, I know when I do encounter another drip, I'll be in good hands with Cornerstone. Thanks for taking care of things for me.

We had an emergency due to a water leak in our front yard. We called Cornerstone Pros. and were very happy with the quick response. Reese was our service tech. He was very knowledgeable and respectful. He gave us our estimate and arranged for the crew to come in and do the necessary work. Our problem was resolved that afternoon. We will definitely call Cornerstone Pros. in the future.

Always courteous. I make the appointment with ease. Receive two text messages prior to the date of service. Get a phone call from tech when he expects to arrive. On time. Wear plastic covers over shoes to help reduce tracking in dirt. Knowledgeable, helpful, courteous. Excellent service

Ronnie M was just here, did a thorough AC inspection and found I needed new capacitor. I also decided to get a new Start Kit installed, he explained it all in detail and went right to work. I would recommend Cornerstone and Ronnie for any of your AC needs. Very personable young man!
