HVAC reviews in Houston, Texas

These Folks are awesome! I have been doing business with them for 15 years, our AC wuit cooling on Tuesday evening, I called Michael the owner at 9:00 a.m. on Wednesday and had a technician out here repairing my AC by 10:30. Quality, reliability, professionalism, and on time service. You cannot go wrong using Cornerstone!

I called Mike in the morning on a Sunday to come check our AC unit that had gone out late that night. Within an hour he was at our house and was able to replace a part and fix the problem. We had to keep the AC shut off for a few hours to allow the unit to cool down, and when we turned it on it was still over heated. I called him and he quickly returned and was able to cool it down and get it started up. We are very grateful for his quick and attentive service on a hot summer day in Houston, and to be so prompt on the weekend was something we are very thankful for. We will be calling him in the future if we ever have any other problems!

I dealt with Mike, the owner, while going thru repairs after flooding. He was very polite, adjusting and friendly and made two trips for diagnostics. He waived all the diagnostic fees and charged me very fair price for the remaining work. He explained me all the repair work very well and professionally. He is very smart and knowledgeable in this field and does his work with passion. He may come across little too strong to some people, but he knows what he is talking about. I will definitely use him again.

Mike at Cornerstone has been servicing our a/c's for over 15 years. I totally trust his recommendations and advice. Mike is always there when he says he will be there. He is extremely knowledgeable in his field. Mike's prices are very fair; he only fixes what's wrong, unlike so many other service people. One of Mike's attributes that I find phenomenal, is his ability to remember names, addresses and work history...no matter if it was a month ago or five years ago!! He is amazing. I just cannot say enough good things about Mike and Cornerstone. Give Mike a call when you need a/c or heating service!! You won't regret it!!

I've had such great experiences with Cornerstone. They have installed all new a/c and furnace systems for me, brought my energy cost down by more than half. My neighbors got jealous and called Cornerstone and he did the same for both of them. We are all big fans of Mike and his excellent crew at Cornerstone.

Just completed another positive visit with Mike of Cornerstone Air Conditioning and Heating. As with the past 12 years of Mike servicing our air conditioners and heaters he was very prompt, polite, informative, and fair in price. We have never had any disagreement with any of his services and we have referred him to many friends and neighbors. Our own children use him regularly for check -ups as well as maintenance for their home units. 5 stars isn't enough of a rating for this trustworthy A/C Heating serviceman.

Rude

Great service, quick and fast response!

They improved my a.c. after others failed to do so.

George saved us from a summer of hell with this heat. Could not have asked for better!

The contractors where very polite and clean. I would recommend this company to anyone and everyone.

Does a great job and warranty their work. Highly recommend them for any ac work

Just had George come out and dude, he got my ac running fast. Totally awesome

Quinn is the rudest person I've ever seen. She also refused to give me the manager or supervisor phone number.

Cris(technician) was very nice and knowledgeable of the ac unit. Great customer service and I would definitely recommend this company.

I am very satisfied with services that were provided by this company! Chris was my technician and he is awesome! Very professional and friendly! I would definitely refer this place anyone! 😊 Thank you!

I want to thank Gutberto and Manny for coming to my rescue. They were timely, professional and took the time to explain the process. Will definitely be using them again.

Spoke to Jay came over and did a fantastic job. Was very professional and he knew his job very well!!

Never had them do any service, but this morning I had one of their drivers zoom up on me, get upset for no reason, and get out his car to threaten me. Not a company I would do business with.

Sold my home and they where hired by the buyers and I could tell you tech was very nice and knew his stuff. I was so impressed I said any ac problem they will get my business.

Houston's AC were able to come to my home on time and delivery good professional service, I had a new system installed at my home and i was offered a year warranty of labor plus 10 year warranty on my equipment, i am more than satisfied with the work completed and the good customer service provided by Mrs. Quenna. Thank you!
