We really appreciate Cornerstone's professionalism and courtesy. Their office staff is always very helpful. I really like the text and emails showing when the service person will arrive and a photo of the service person. Even when I my phone cut off the office staff, I was reconnected with the person already working on helping me resolve my plumbing problem without having to re-explain the problem. Chris, the plumber, was very nice, knowledgable, and respectful. While not the least expensive plumber in the area (the office sets the amount for specific services) they warranty the work and get the job done. It is perfect for people like us who just moved to the area and need reliable tradespeople. read more

I paid $160 for them to flip a breaker switch. They charged a $69 fee for the analysis, which is a bit high, but I'm fine with the charge. Then they charged $95 to flip a breaker switch, which is insane. The HVAC guy was in and out of the house in less than 5 minutes. I called management to complain and they stood by the charge saying this was the standard default service fee; I thought that was the $69, but apparently not. read more

The company would not honor the $30 a/c cleaning they advertise on their website. Instead, they wanted to charge me $65! No one at the company knew how much they charged per pound of freon. Even the dispatcher had to "call a manager." After pressuring them to find out what their pricing was, I finally got someone to reveal to me that their price per pound was THREE TIMES the going rate! The only company which won't reveal their pricing until you commit to the work is a shady one which will never get my business. read more

Outstanding professionalism. We 1st used them when one of our A/C units froze up on July 4th. They were prompt, offered a detailed breakdown of what the issue was, and what options to consider with the prices of each. We called them again when we had a clogged drain at Christmas (it always happens on the holidays!) when a manual snake wouldn't clear it. We had them come out on the 26th. They gave a time estimate, then called back to say they were running ahead of schedule and wanted to make sure it was OK to arrive early. Jerry was the tech who came out, and we were so impressed with them again on this 2nd visit we had them also look at replacing our aging hot water heater. Again we were given multiple options (with pricing) and invited to check around to see if it was a fair price. We did and it was. Despite it being what is in effect a holiday week between Christmas and New Year's the new water heater was installed in a custom location we had wanted, on budget in less that 48 hours after we gave the OK to do the work. Highly recommended for any plumbing, or A/C needs. read more

Some neighborhood kids were playing in my side yard and managed to throw a bat and bust the main water valve into my house. Cornerstone was able to send someone out that evening, within an hour of being called, to get this issue resolved. The plumber that showed up was fast, professional, and did a great job getting this issue resolved. He even managed to make the repair so that the valve no longer sticks out as much as it did when the builder installed it to help prevent any fluke, future catastrophes. Great job and customer service by Cornerstone on this job repair! read more

Cornerstone Air and plumbing. Great people from phone call to Curtis the technician. I called with a couple problems 1 a hammering ( water spurting and banging)in the Kitchen faucet. The wife complaining of a bad smell when the a/c was on. Cornerstone discovered somehow the faucet was a almost closed valve. Done. They could have told me anything. They are honest. Curtis showed up to clean the vents, on time , clean, sharp.Done. Smells great. . These are the people you should use. read more

I called and a technician was out to help within a couple hours to service a clogged drain line from our AC unit that was leaking in our garage. The office staff were very nice and helpful. Matt was our technician and he was great! Got right to work to fix the problem and gave me great tips on how to avoid the issue in the future. Highly recommend and will call on them again in the future for any issues. Thank you! read more

So my toilets been dripping for about two months now, and now it hasn't fully flushed in 2 days. I decided to give this company out since there has been such positive reviews about them. I'm really glad I choose them. I didn't have enough time to call about the service so I filled out a form online. I probably for a call roughly 2 hours later. The lady on the phone was very nice and accommodating and we set up a time for the plumber to meet. He was right on time the next day. Well, actually 10 minutes earlier then expected. His name was Michael and he was very sweet. He answered all my questions, gave me a few recommendations and went right to work. He was spot on about what the issue was was my toilet. I'd definitely recommend them! read more

I had Gary C. come over for a clogged sink and garbage disposal. Cleared my problem with no issues. Quick, friendly service and very knowledgeable. I'd call and request him again but hopefully I don't have to. read more

Cornerstone installed our unit so we called them when the lines were clogged and the air was not working. We called on Monday night and they said they could come on Wednesday. Not exactly great emergency service. We called someone else and they were here within an hour. Disappointed and will not be calling them again. read more

Josh, the Cornerstone technician, performed the regular checkup and maintenance on our HVAC this morning. He was prompt, professional and very helpful. He even changed all five filters on the returns in our ten-foot ceilings for this 76-year old customer. I am completely satisfied with his work. read more

Called Cornerstone one morning about strange electrical problems going on in my house. They had someone out here in less than an hour and a half. They tracked down the problem and fixed it in no time at all. Terry was a super nice guy and knowledgeable. I signed up for their AC, electric, and plumbing annual contract because it seems like a really good deal. I would like to add that their price for coming to my house and checking all of my electrical stuff was very reasonable. I highly recommend them and will use them for all my future needs in their areas of expertise. read more

I used this company for an electrical issue I had. Manny arrived on time, he took all covid precautions & followed CDC guidelines. He explained to me everything he was doing. I was very impressed. Knowledgeable and friendly. A++ would recommend and will use again if ever needed. read more

Reese came out a checked my ceiling for a possible leak. It turned out to be inactive and he later found that my leaky water heater was still under warranty. So he saved us $600 on replacing the other issue we had lingering over our heads. We highly recommend Cornerstone. :) read more

I am writing to tell you that I got totally ripped off by the fine folks at Cornerstone. The office set up the appointment and the slick salesman/Electrician showed up on time, but that was all that was good about the work. He began by walking through my list of electrical work items, taking pictures of each task and gave me a price of $424.00 before the work started. Then after only one hour ,said he had to go and never finished any of the tasks. The workmanship was shotty and none of it complete. I am very disappointed with the overall experience. read more

Not sure a jack of all trades can be the master of your issue. Had him out to evaluate the AC over summer of 2016 as I wanted to replace it. While measuring voltage, he blew the transformer that supplies power to the interior thermostat. BIG shower of sparks, except July 4th was last week. Then started denying it. Said he had to go to the shop get another (10:1 stepping xfmer and AC guy does not have one?) and left. I probably should have complained, but the next guy I had came in far more competitive than any of the other 4 and had also done my mom's home, so I just moved on. He also replaced the transformer for no cost. Perhaps their other techs are better, but don't deny issues to someone who is familiar with HVAC. read more

Keil did a great job with my repair estimate. He provided me all the information I need to make an educated decision and feel confident in my choices. He was prompt, efficient and polite. I give him 5 stars! read more

Excellent service and really quick response time.(Under 3 hours) Great guys who explained what they were doing and what we could do going forward. Happy to give other advice and no hard sell of service. Would recommend highly read more

Gary arrived promptly at the scheduled time to check out my hot water heater. He was very nice and explained everything in detail. I had a new water heater installed within a few days. Everyone was very helpful! read more

I called Cornerstone because they are a business in the vicinity where I live and I wanted to give them an opportunity to earn my business. The office person was very friendly and set up an appointment for a salesman to give me a second opinion on replacing my central air conditioning. Michael showed up on time the same day with a big smile and an eager to please attitude. He LISTENED to everything I said which to me is most important! By LISTENING, he was able to determine what my needs were and explained how his company could best meet my needs. I wound up making a purchase right then and there knowing I was getting a good deal and a good product. I would highly recommend giving Cornerstone the opportunity to earn your business and hope you have the same experience as I did. read more

I use cornerstone pro's for my electric, plumbing and AC. Every service person has been professional, knowledgeable and on time. I would recommend them. read more

Gary C. was a remarkable plumber. He notified us of the plan he was implementing to find the solution. Found it quickly and had it fixed in less than 20 minutes. Gary was polite and very knowledgeable. He made the appointment painless and even enjoyable. We have used Cornerstone Pros for electrical, heating and air, and plumbing. Always on time. Always curteous and efficient. Thanks Gary! read more

DO NOT USE Cornerstone air. They are a dishonest company/ manager and owner included, with incompetent, unskilled service techs. I bought a brand new a/c unit from them- very expensive. I also purchased a service contract with them to maintenance the unit. They sold be a unit that has had multiple problems. They have been unsuccessful with repairing the unit. They have avoided all of my calls refusing to come out to do warranty work and let me use my service contract. They have admitted that the unit is faulty and want to wipe their hands clean of it. They left me with a big mess of water stained and mold covered ceilings and a mess of an mold and water filled attic. In addition, they have dishonest repairman. On one appointment that I had with them, the tech asked me if I had any other problems in the house and I did have a problem with my dryer vent. They Cornerstone tech sold me that they repair a/c, plumbing, and electrical, and he would gladly repair my dryer vent. He did the job and he said his credit card swiper wasn't working so I had to pay him my cash or check. I wrote him a check and he said that he would bring it to Cornerstone and write up a invoice and mail it to me. The work he did was faulty so I called Cornerstone to ask them to come to look at it. The manager/owner of Cornerstone air said that he knew nothing of this repair and refused to take responsibility for his employee. He told me that the company was not responsible for their employees doing this type of work. I have been trying to get them to come out for nearly a year now to come out and paint the ceiling that was supposed to be covered under the manufacturers warranty due to a faulty unit. I have also been calling them to have a service man come out to service my unit because I have water and mold all over my ceiling right below the a/c unit. They have avoided my calls and just finally told me today that they didn't want to service my unit anymore because there have been too many problems with it. They recommended that I find a different a/c company. Cornerstone is fantastic about taking your money to purchase and install a new a/c unit and sell you a maintenance contract but are incompetent and unwilling to make good on a faulty unit that is still under warranty and that they sold you a service contract for. Cornerstone has been nothing but a VERY EXPENSIVE, time consuming, home damaging headache for me. I HIGHLY suggest not engaging in business with them. read more

Had my water heater installed and guys were awesome !!! We had some set backs due to my HOA but Josh and Robert were great they did amazing job !!! Very nice and professional . read more

I contacted Cornerstone Air because I saw the positive ratings from other sites. the gentleman who came out was punctial and extremely nice. However, this company is extremely overpriced. He let me know I had a bad freon leak coming from my coils and that i would require purchaisng a new unit. The prices for a 2 ton unit were from $4K-$11K, which is extremely ridiculously expensive. So instead of purchasing a unit from them I chose to get a second opinion and that individual told me that the coils just needed to be replaced not the unit, which would only cost me about $500. BIG difference. I'm glad I didn't go with Cornerstone, or I would've been out $5400 dollars. I would not recommend based on pricing. read more

Nice work replacing a leaking coil in our air handler; efficient and very effective. Top notch professional job performed by Scott and a day or so earlier Matt. Cornerstone is a great company to do business with in my opinion. read more

I am very happy with the work Cornerstone performed in replacing my heat pump. We replaced a 14 year old unit that was making a lot of noise. The new unit works great! They were on time and were very neat. The county inspector also told me they did a nice job. read more

The only reason I use Cornerstone Air is because of Donald Smith the Technician, If Donald leaves I will take my business wherever he goes. I have been using them for years, they send out these young inexperienced techs who do the basics and try to upsell you to death. Donald came in and noticed that I did not have the proper shut off switch that should have been installed by the builder 5 years ago when my house was built. It should have never passed the county inspection. Anyways, I filed a warranty claim with my builder and it was installed, how their techs could have been servicing my house for all these years and not noticed?! Donald is old school and knows his stuff! People in the office are useless.... read more

We came home from work to find our house at 88 degrees and the air conditioner blowing out hot air. It turns out the fan motor stopped working, so we called around right away to find someone to come out that night. Luckily, Cornerstone sent Matt out an hour later at 8pm to replace our motor and get cool air flowing again. He was very nice and helpful and we thought the price was reasonable for the repair. Other places said we had to wait until the next morning, but the fact that they came out that night earns them 5 stars! read more

Purchased the $49 Angie's List Deal for A/C Maintenance, Cleaning, and Tune-Up, including a Duct Fogging sanitation with One Pound of refrigerant. They reasonably charged an additional $29.95 for second A/C unit. Super communication with company. Answered each email promptly. A technician named Matt arrived and immediately put booties on his shoes to protect my floors. He introduced himself and explained everything he was going to do in great detail. He was meticulous and thorough....he took his time -- was not rushed. I was super impressed with the overall experience with this company from beginning to end. If you are a Angie's List member check out their specials. They also offer competitively priced warranty packages. read more

Had Cornerstone come out to The Villages to check our furnace for the winter. Discovered the aged furnace was quite old. Was quoted a price to bring it up to par but decided that because of its age we would be better to purchase a new one instead of putting more money into an OLD unit (17 yrs ). Pricing VERY fair. Best decision we made. Very happy with price/service. Punctual/professional and courteous. HAPPY...HAPPY....HAPPY read more

Showed up in time! Great start! With little delay the tech asked me what the issue was. The tech started messing with my a/c looking for the issue. (Even made a joke at a previous companies attempt at fixing my a/c). The tech found mold in my system -which I had suspicion of but other companies had shrugged it off- and got to work cleaning the lines and getting rid of the mold. Installed a uv light to prevent mold growth too. I paid more than I wanted too, but I also wanted to have a working a/c in my house. Let's see how it works, if all is good in a few days I may sign up for the maintenance package. read more

Chris came out and looked at our old water conditioner tank almost 10 years old and was very honest and fair with his assessment and recommendations. He even tried to fixed a disconnected hose causing water to spill out and rust on our garage floor again showing us clearly why we will need a new unit. Very professional, knowledgeable and reasonable quote. Will definitely call him back out in near future! We live in Lutz and see a lot of Cornerstone trucks which is why we decided to call and glad to give a reputable local business our business! Thanks for great service Chris!

A/C stopped working and called Conerstone after reading other reviews. I am pleased to say their service was outstanding. Donald was our technician and he was professional and explained everything to us. Very impressed and will recommend to friends and family. read more

I purchased a top of the line Lennox A/C System through Cornerstone in November, 2013. There were a few issues that arose immediately, including a service person who claimed that "You can't get humidity in Florida below 50% or you'll get nose bleeds", but ownership stepped up and made everything okay. I was pleased with the system and looking forward to having a good, local AC contractor lined up for future service on what I believed would be my last AC purchase ever. Fast forward to July 4, 2015, when the unit stopped working. A service call the next day ($89, high, but not out of line for a Sunday) identified the culprit as the condenser fan motor, which was covered under the warranty. The labor, however, was not. The service man stated he would order the motor first thing Monday, with plans to do the job the next day.. The repair required disconnecting 5 wires, removing 4 screws to lift off the top grille, removing 4 nuts to release the motor/fan assembly, then loosening a single bolt to remove the fan blade from the motor shaft. Reverse the process with the new motor and the job is done. Cornerstone's quote for this service? $439. When I asked how much time was required for the work I was told that Cornerstone does not use hourly rate pricing, and has flat rate charges for every job. The tech also tried to sell me a "club membership" that would get me a 10% discount on that fee. I objected to that price, which I considered exorbitant, to say the least. I then received a polite call from the service manager attempting to justify the price by delineating all his costs associated with acquiring a new part under warranty. When I responded that I understood, but simply could not afford such a high labor charge and asked him to call me when the motor arrived so that I could pick it up and do the work myself, he informed me that Cornerstone would not release the part to me. His best offer was to apply the $89 service call fee I had already paid against the $439 fee. I called a local competitor, Ierna A/C. The Ierna rep suggested I have a service call for a second opinion, and said the fee would automatically be applied against any repairs. Since I already had a diagnosis, I declined. The part was ordered and the job was slotted for between 8 and 10 on Thursday . However, I was pleasantly surprised to receive a phone call on Wednesday afternoon informing me that the part was in and that a tech could be on-site in 15 minutes. Long story short, Ierna did the job, quick and simple. Better still, the $140 quote was reduced even more with a $25 coupon my wife found in the paper that morning. Cornerstone AC will never work for me again. I urge anyone considering hiring them to seek out a second quote and save serious money. read more

Once again this company has proven themselves to be honest, trustworthy and professional. Making an appointment was easy and the operator was professional. The technician showed up on time, was very professional and was able to fix the problem in under an hour. He didn't try to sell us anything expensive or exaggerate the problem. Fortunately for us it was a small issue which was resolved quickly. This company may be a little expensive but it is worth it for the piece of mind knowing that they did things right. read more

After some issues with the 3 ton unit originally installed, Cornerstone swapped it out for a 4 ton unit at no charge. The new unit has been operating without issue! Yay!! Thanks Cornerstone! read more

Start by saying they are very nice people! But... I couldn't get even a ballpark price for the work I needed. Even after I called several times. I had a kitchen sink, faucet, and garbage disposal to be installed. I had to pay them to come give me an estimate. If I would have got an idea of the price, it would have saved them time and me money. Their quote was very very high and I could not use them. But again, everyone was friendly and they did show up, so that means something! I wish it just didn't cost me $60 bucks just to meet them! read more

I had a coupon with tune up for $39 value (1 lbs freon free included if freon was low). When he comes up, freon was low and there was chance of leak. So he made it service call as it was low in freon and AC was not working well according to him, and further the leak detection was chargeable to $198 + freon (chargeable for all)+ fixing it (unknown price). Now coupn says "if low on freon" in AC tune up and technician says "service call" if low in freon and then makes it a leak detection. So 3 star. As it seems complicated to me. Tune up means clean up drain lines, check for any leak and that all parts of AC are working fine. But only got freon checked in service call/ tune up but paid for all as coupn was waste. We just got freon added and AC is running well. I m not prepared to pay for leak detection and fixing as AC was checked 6 months back by AAA airwaves and 2 lbs freon was added too (Sept.) when they came to see AC stopped (coz of ice). So 99% chances last company cheated on us. I have had experience with 3 companies so far and just end paying much more everytime and worst part is AC is 2014 built. I need recommendation on right AC company. read more

I cannot say enough wonderful things about cornerstone. My husband and I bought our first home recently and had 3 inspections prior to closing only to find out that the house was a disaster and no one actually inspected anything! Their electrician Chris came out to meet with us and inspect the house and unfortunately we had to rewire everything. Chris worked with us through the entire process. He and Wiz did all of our rewiring and then some. I cannot say enough about their work ethic, they did everything they could to make this a comfortable and easy process for us. They were also a lot of fun to have in the house, both of them are characters which made it less stressful for us. We've also had cornerstone do some plumbing for us as well. I'd refer them to anyone. read more
