Cornerstone Pros

Came back from a 7 day cruise to find out that our upstairs AC unit had stopped working. I was very nervous about how things might turn out as the unit is around 7-8 years old. I tried some basic troubleshooting but no luck. Rob W. was the tech that came out to our home and within 15 minutes he had diagnosed the problem; a frog had crawled into our drain line and plugged up the works. Cornerstone could have easily told me the unit was DOA and I would need a replacement but instead, Rob W was very honest and charged us only for the work performed to get the pipe cleaned out. Could not be happier with their work, will definitely use again in the future. Thanks!

A/C Tech Rob W. was very knowledgeable and professional and answered all questions without hesitation. Their scheduling staff and employees answering the phone were very courteous. They behave as if they truly want your business and want to do a good job. Overall, excellent experience.

My upstairs toilet stopped filling water after flushing. This happened a few days ago and I could not use the toilet unless I filled water in the tank manually each time I used the bathroom. Uggh I used yelp to find a local plumber and based on reviews, I called Cornerstone. The customer service associate, Caleb was very helpful in setting up an appointment for today. Gary C. was the plumber who arrived. He was very cautious about not getting dirt in the house. He diagnosed the problem as a broken fill valve and recommended changing the fill line from the plastic one we had to a metallic coil with brass ends. He said that type was better since it could be bent and still work well. He did the repair in less than 30 minutes and was able to knock of $20 off the initial service call. He was able to send an invoice to my email for my records instantly which was appreciated. Gary was very amenable to my asking lots of technical questions and was very friendly. While I hate repair, Cornerstone made it a very painless experience. Thanks!

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!

Customer service is huge for me, and I was really impressed by this company. Both of my AC units went out on the same day (when a different company was performing maintenance). I was scrambling to get quotes and get the install done. Everyone I talked to was friendly and helped me as best they could. I felt like everyone really cared. Matt did the quote and was so knowledgeable and friendly. T.J and John R. were the installers and they were considerate and kind, and ensured everything worked properly. The brand was not one I was familiar with, but I came to learn that was just in the US, and that they were huge globally. I was able to get better functionality than if I had gone with another provider's Trane units. We have now had the units for a month and they are so quiet, and are definitely cooling just fine. The one suggestion I would make to you, if you need a loaner unit, ask them to give/put in the ventilation duct. The person who delivered it may have just forgotten this. Overall, excellent experience, and I plan to use them for my future AC needs.

I have been relying on Cornerstone Pros for a year now and have never had a problem with them. They have installed a new A/C system last year and have addressed a plumbing and electrical issue recently. There is a pond in my back yard with a fountain that quit working. I thought it was an outside switch to the fountain but they determined there wasn't. The two service men were going to walk out into the water to try to determine the problem but I advised them not to. Despite telling me it would be another charge to come back later if they obtain a boat to check the fountain I told them to get the boat and come back rather than walk out into a muddy silt filled pond. Most recently I had an estimate on a stand by generator. Michael took time to explain everything and answered any questions I had. I recommend them for HVAC, electrical and plumbing problems.

Where to start? These ladies and gentlemen at Cornerstone have never let me down. I first came to them several years ago after one of their competitors wouldn't make right on a problem that never seemed to end. They fixed my system then and they have just done it again. Scott came out first and spent 5 hours running down the probable cause and when he needed a fresh pair of eyes, he made the call to the office and got Brandon and, their newest technician, William out on the same day even though they all had full schedules. They finally found the problem tucked away deep in the duct work where a bunch of wires were melted together (their best guess was from actual construction, which I would have to agree with that assessment, as we've had weird problems since we bought the house. After they finally found the problem, they fixed it in about 30 minutes. Courteous and professional all the way! I would also like to give commendations to Matt and James for services in the past that I've never done a review for! I know that no company can be all things to all people, but give Cornerstone a chance to earn your business, I don't regret it for a second!

I have done business with Cornerstone a few times in the past once for an AC repair, which they had to come back because it was wired improperly and for a new unit install. I was never too impressed, however the were able to come out fast so I gave them my business. This most recent time I called them out to check the AC on a rental unit. They scheduled with the tenant. Checked the unit and left. The technician called me from his truck to tell me he was writing up an estimate for repair and would email it to me. What good is an emailed estimate. I called to get the Air working. I was upset because they made no effort to actually fix the issue. I knew at that moment I would have to call someone else. I waited 3 days and still no email. I called the office, they said ooops, we have the wrong email address. The written quote was over $1200.00 A tech from another company came out, fixed the issue. Charged me $125 and it has been ice cold ever since. When I called I asked them to waive the service call fee. They refused. Not that they would care that someone is without AIR from the time it takes them to get back to me. They did have a working phone number to text or call, and in the mean time people are suffering in the Florida summer heat without air. I will never call them for anything ever again. In addition to paying top dollar that comes from a big company, they have lost my trust forever.

These guys came out to the house, did their inspection, an recommended a way ahead when one of my 3 units failed. The install was professional and painless on my end. They were professional and they cleaned up behind them. They took care in removing molding around the attic access and re-installed it when complete. The new unit working great. Only ding was that they did not schedule me for the county inspection once complete. They are my new AC service company for the future. Thanks.

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!
