Our AC went out in 2012 and we called Cornerstone Air to repair. We were told that because of the age and condition of the unit replacement was a much better option. We would save on electricity, repairs, etc with a new unit. We went ahead and had them replace the unit with a higher end model (with a higher end price tag) with a two year service contract. We were really happy with the new unit for about a month. Then the touted saving on electricity did not show up. Also the air conditioner did not keep the house a comfortable as the previous one. We called the company and they said we might not see savings and that the thermostat might be off. They came out and determined that the thermostat was not off. That was it. So we are already not thrilled with the unit, and it breaks down within a year of installation. We called them out to service it. The service technician tells me it would be $300 for the repair. However, as part of the purchase we received a two year service contract. When we told the technician that we were under a service contract he said he knew and it still would be $300 dollars. So we had to call the office and speak to the manager. We are told that the drain line was not installed by them and therefore not part of the unit. I pointed out that it should have been flushed as part of the routine maintenance that Cornerstone preformed not 3 months previous (and has a 6 month warranty). Fast forward to nine months later. The thermostat is not working. Again out comes a technician. This time it will be $200 dollars to replace. Again the manager gets a phone call. We point out that the thermostat was installed by them and is not old enough to not be functioning. Again no charge for the service call but this calling the manager thing is getting old. Fast forward another 3 months. Water is found in a back bedroom and closet. We found 2 inches of water at the base of the AC unit in the garage. This time the float switch is defective. As a result of the float switch not turning the unit off, the drain pan overflows and soaks through the wall an into the carpet in the next room. This time we are about a month out of the two year service contract but still well within the 10 YEAR parts warranty. This time the technician said it will be $500 to clear the drain line and replace the float switch. Then came another call to the manager to have them honor the part replacement policy. After some discussion, the manager agreed that it was in fact a warranty issue. The manager also says they will have someone come out and asses the damage to the carpet. They called a carpet cleaner who can do nothing because the carpet pad is wet. Cornerstone was supposed to call a flood/water remediation service and tell us when they are coming out. No return phone call from Cornerstone. When we called them to find out when these services were coming because we have wet carpet in the bedroom and we are not interested in having mold, we are told that actually this part did not fall under the warranty. We pointed out that this part was installed by Cornerstone as part of the unit. We did not pay a separate line item of float switch and installation and the AC unit will not function without the float switch installed. Also the technician had told the manager a untrue account of what had happened at the time of the service call (there are 4 adults that were present that can attest to "our version"). Manager says she will call the owner and get back to us. Three days later they are not returning our phone calls. We went ahead and removed the wet carpet from inside the house since we were concerned about mold and have scheduled to have the carpet replaced to the tune of almost $400. We will not be using Cornerstone again and would highly recommend steering clear of them. I should also note that the old AC unit that Cornerstone replaced only needed TWO service calls in the 6 years we owned it and one of those was the one where Cornerstone recommended replacement. read more

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! read more

Title: A Nightmare Experience with Cornerstone Pros: Lack of Expertise and Unprofessionalism I recently had the misfortune of dealing with Cornerstone Pros for my HVAC service needs, and my experience has left me thoroughly disappointed and frustrated. The numerous issues I encountered throughout the process have compelled me to share my negative experience with others. One of the most glaring problems I encountered was the apparent lack of knowledge among their technicians, specifically when it came to working on Daikin units. It was evident from the start that they were ill-equipped to handle the intricacies of Daikin systems. Instead of admitting their limitations and recommending a specialist, the technicians attempted to work on my unit, leading to further complications. Upon realizing the inadequacy of their technicians, I decided to escalate the matter and spoke with a supervisor named Justin. Unfortunately, this only exacerbated the situation. Justin not only lacked the professionalism one would expect from a supervisor but was also argumentative and rude throughout our conversation. Rather than acknowledging the shortcomings of his team, he chose to defend their actions and downplayed the severity of the issues I was facing. After an incredibly long and frustrating conversation, Justin advised me to call him back once the service call was complete. Trusting that the company was committed to resolving my concerns, I followed his instructions and reached out to him as soon as the service call concluded. To my dismay, days passed without receiving any response from Justin. When I finally managed to get in touch with him, his attitude was unchanged, and he seemed more interested in arguing than addressing my concerns. The lack of communication and unprofessional behavior from the supervisor was the last straw for me. I had endured enough frustration and decided to cancel my service with Cornerstone Pros. It is disheartening to witness such a blatant disregard for customer satisfaction and professionalism from a company that claims to be a reputable service provider. In conclusion, my experience with Cornerstone Pros was nothing short of a nightmare. From technicians with inadequate knowledge to a supervisor who was argumentative and unhelpful, the entire process was riddled with incompetence and unprofessionalism. I strongly advise others to think twice before entrusting their HVAC needs to Cornerstone Pros, as my experience has left me with a sense of regret and disappointment. read more

Months ago, on a late Saturday evening, our AC stopped working. Because it was well after 7 p.m. we decided to see if the unit would come back on - if it had possibly frozen-up. Well, by Sunday morning it still hadn't reset. We knew it had power, we had checked the breakers and basic things. We contacted Cornerstone. The call went from their answering service to a coordinator in MINUTES! Their service coordinator contacted us, knew what to ask and then gave us a service window of about 2 hours. Well before we expected, John Rubio the technician called to say he was on his way. He arrived shortly and resolved the problem - it was a clogged drain line / float positioning issue, which he repaired quickly and efficiently. I can't say enough great things about him. He was friendly, professional and knowledgeable in his field. He explained things as he worked, and treated us very well. Our relationship with Cornerstone has been ongoing for several years now and I foresee it continuing down the road. Their people and service and equipment is the absolute best. It is now my pleasure to confirm my previous assessment and review: Since 2012, when we had Cornerstone replace our previous unit, our experience with Air Conditioner maintenance has become so much more pleasant. It's great to deal with knowledgeable and courteous people; and it has been really phenomenal how they LISTEN when I explain any issue we've ever called-in on. They are PRO s, no doubt about it - and they SHARE insight to avoid future worries. If a recommendation needs to be made, they offer several choices - they know it's not a one-size-fits-all business. And they arrive on time or call well in advance if there is any delay. A really great team. I recommend them highly. - I would not change a word! ... and now it gives me great pleasure to ADD on February 7, 2017... Our A/C unit stopped working ... I called Cornerstone, it had been months since the last time I needed service. I received prompt service from Chris Evans. Because the issue was one that had been handled by Cornerstone previously and because it occurred within the past several months, after finishing-up I was presented with a NO CHARGE - no service call charge, no laber or parts charges - FANTASTIC! I can't tell you enough how great all of their personnel are! 5-star recommendation stands! read more

Alvino, Richard, Justin, John, & TJ, we can't thank you all enough for the kindness, generosity and professionalism you all showed us. We experienced an absolute AC nightmare that we dealt with for a little over a year with another company. An undersized AC system, along with ductwork was installed last August in our home. Needless to say we experienced month after month of constant cooling issues as well as high electric bills. After that company basically refused to help and listen to us, we decided to seek other opinions from 3 different local companies. All 3 companies came to the conclusion that our system was undersized for our home based on a proper heat load calculation. We decided to give Cornerstone our business. Alvino arrived at our house on Tuesday evening and returned Wednesday with a diagnosis and plan. By Thursday the crew was replacing our ductwork and Friday (today), we have a brand new AC system up and running, that is sized appropriately for our home. Needless to say, we are so comfortable going to bed tonight. We are so impressed how well everyone communicated with us during this process, from the answering service to the dispatchers and secretary along with the text notifications. Cornerstone is an amazing company. We are so happy that we decided to give Cornerstone our business and will definitely be using and recommending you all. Thanks again from the bottom of our hearts. We are so thankful. Aaron & Ashley Springer read more

Our master shower had been useless for nearly 1.5 years - no cold water pressure. Several plumbers looked it over, but left without resolving this issue, citing how big the job would be or denying we had an issue at all. After looking for a high review plumbing company, we found Cornerstone Pros. Jeremiah and Geovanni showed up as scheduled, joined by Austin W., and the three gentleman sounded like scientists as they discussed what could be wrong, explaining (to me) their "experiments" to troubleshoot the issue, and determining best course of action. At the end of the day, a massive glob of glue or Teflon was recovered from the main manifold of the house that feeds cold water directly to our shower. AND IT WORKS AGAIN! These three guys were a pleasure to have around the house as I continued my daily work calls and office tasks. They were thorough, polite, very knowledgeable, and prideful of their craft. We couldn't be happier. As new members of Cornerstone Pros, we have since purchased an amazing water softener and look forward to working with them on our electrical needs in the near future - at discounted rates! Thank you guys SO MUCH!!! read more

We are retired people. I am sorry to say but we have grown to be somewhat "suspicious" of repair people when we need a repair or service completed. We needed a garbage disposal replaced, recently. We know what the word "Cornerstone" means in the Bible, so we thought that this company must be built on ethical principles and professionalism. We found the answer to be YES on all accounts. Kiel was our plumber and representative of the company. He was neat, wore those "booties" and did an excellent repair. He indicated that our kitchen faucet might need replacement, as well. He "walked" us through the procedures to hopefully get a new faucet under a company that offered a "life-time guarantee" for a free replacement. As I write this, Kiel is replacing our kitchen faucet. We are very pleased with this company and their representatives. We want to "Thanks" to Rick for keeping us current as to when Kiel would be here for the repair. Sometimes those "four hour" windows for waiting on a repair can be anxious. Rick kept us informed as to when our repairman, Kiel, would arrive. Thanks, again Cornerstone Plumbing! read more

I am only reviewing the service call. I have used Cornerstone for a couple of different jobs and some jobs seem to be a little on the higher end, but this review is about the service call on my AC unit that was installed in February. I noticed a large water spot on my laundry room ceiling on a Sunday morning. The spot sits directly under my AC unit. Called Cornerstone and Ronnie was sent out later that day. Have dealt with Ronnie on another visit and each time he has been very professional, solved the problem right away, and given me advice on preventive maintenance to keep any more problems from occurring. I can not say enough about their great customer service. Every tech I have dealt with has been great and because of that I give their techs, especially Ronnie M, a five star rating. I also like that they text me a picture and background info on each tech before they show up, that way I know a little about them and I have a picture to verify they are who they say they are. read more

On 11/16/2020 I placed a review for Cornerstone Pros on Yelp. To this review I am compelled to follow up: After placing the yelp review anonymously and without any link to my customer account, within a day I was contacted by Cornerstone Management. As I did not escalate my complaint nor did I seek recompense, I was as surprised to hear from them as I was they figured out who posted the review. I find it rare that a company goes thru so much trouble to seek customer satisfaction and show such earnest concern. Not only did we have an honest discussion, but they took immediate action to avoid such incidents in the future made me whole as well. Companies cannot prosper without growing pains as nothing in this life is perfect. For their quick and decisive positive actions I must rate this a company with high integrity and therefore, would put my trust in them again. Thank you Cornerstone for turning such a negative experience into a positive one. read more

After several other companies attempted to mislead and take advantage of a family member, we called one more company; Cornerstone. Micheal arrived and was very honest and forthcoming that their unit needed only a small repair where all of the other companies had recommended a full replacement of a system to someone who only receives disability and barely gets by. After this, I pledged my loyalty to Cornerstone, and I have not been disappointed. I have had HVAC and Plumbing work completed by them and have been very happy. Most recently I have had Chris Evans come out to inspect the AC unit in my "new to me" house. I have met him before and it feels like a friend was coming over to help me out. He inspected the unit and told me I was good to go. I could not recommend Cornerstone or Chris Evans more. As a female I am always concerned of being taken advantage of by contractors. I don't feel that way with Cornerstone. read more

My son had whole new unit put in about 1 1/2 ago. We had problems with it sense then. We had you guys out several times to fix it but everyone kept telling us that there was nothing wrong with it or we needed some new parts. No one took the real time to really look at it. So my son called this morning and wanted to talk with someone high up. They sent Matt out, he was here several hours working on the unit. He finally got to the bottom of the problem. He took his time. I told him what was going on. He was a very pleasant person to have listened to me. He promised me that he would fix it. You guys are lucky to have a employee that is very pleasant and kind to your customer's. There are no words that I can say that are enough for kindness. He deserves a pat on the back for the work he does for your company. If we ever need work done again we will be asking for him and only him. read more

After returning home from dinner, my wife and I arrived to hot home due to one of two A/C units which failed. Needless to say, it was an unbearable sleepless night. The following morning, I contact Cornerstone Pros and was relayed to Pam. Due to our attendance at our friend's wedding, we had to delay the service call to noon. Unfortunately, the wedding events ran later than expected and we notified Cornerstone Pros. They rescheduled to a 4:00 pm to 6:00 pm time frame. Well, Service Tech (Ronnie) called ahead to make sure the problem still existed. Ronnie promptly arrived and quickly resolved the issue (defective transformer in upstairs air handler). Additionally, Ronnie verified no other problems existed in the A/C units before ending his service call. Special Thanks to both Ronnie, Pam, and the Cornerstone Pros Team. Maurice M.

One of the best experiences I have had with an "unknown company" coming to do night emergency repairs to a water pipe leaking into our garage. The receptionist on the phone was wonderful and kind; I was given specific times the repair man would arrive (and his picture!). He, Danny, was pleasant, well qualified, work extremely hard drilling and chipping through concrete to get to the leak, and never seemed frustrated when the job took lots longer than anticipated. By evenings end, we felt like best friends, and they (his supervisor also came to bring more drilling tools) shared great advice on other plumbing needs we have upcoming. I highly recommend this company as they meet all my expectations in every aspect of our dealings with them. Lastly, for all the work done, the price was very reasonable. I will use Cornerstone again! read more

My tankless water heater was running an error code which resulted in no hot water in my home. I called Sunday morning and Cornerstone was able to have someone out there that day. The technician had to come back on Monday and talk with the manufacturer to run diagnostics. Long story short a part was defective and had to be ordered. Cornerstone was lockstep and very transparent with the entire process. The technicians were very professional, courteous and took time to explain the process. This was my first experience with Cornerstone and can say that they will be my first choice for all my AC, Plumbing and Electrical needs in the future. Now more then ever during this pandemic, it was refreshing to know that we can count on a company such as Cornerstone to serve their community. Much appreciated!! read more

I had Cornerstone Pros A/C, Plumbing & Electrical give me a quote on changing valves for my hot and cold water in our bathroom. Then I asked for a quote for installing a new sink and faucet. The quote was reasonable. I ordered a new sink and purchased the faucets. The sink was the wrong size. Martin, the plumber, called their warehouse in Tampa and found a drop in sink my color. I went down there and picked it up. Martin came back that same afternoon and installed everything. All is great now, everything looks and works great. I highly recommend these folks. They not only do a great job, but, they actually care about the customer, something that is lacking in a lot of businesses these days. Thanks Cornerstone and Martin. read more

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. read more

I found Cornerstone on Angie's List about four years ago to repair a leaky faucet in the Master bath. I was impressed with the professionalism and courtesy and decided to become a member of the service club. Since then they have replaced my A/C unit, water heater, and installed a electrical outlet in the kitchen closet to hang my Dyson. Today Martin arrived on time to perform the yearly inspection of all the plumbing areas in my home, he recommended a few things to replace that could become problems in the future. He answered all of my questions and didn't leave until he knew I had no more concerns or questions. I highly recommend Conerstone Pros to anyone needing Air, Plumbing or Electrical services. read more

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 requesting Albert to always be our Tech so good job ​Cornerstone hiring good people. read more

I don't usually leave reviews but I felt Cornerstone deserved one. Our air went out on a Sunday and not only did cornerstone come out quickly they charged less than all the other ac companies on a Sunday. The technician spent an hour diagnosing the problem and even though he could not fix the problem (bad coil) he was able to get us cooling. Coils werenon back order and when our ac went down again another technician came out quickly and got us going again. As soon as the coil came in they got us up and running even though their own office did not have power due to Hurricane Irma. Every technician that came out was polite professional and friendly. Cannot recommend this company enough!!!!! read more
