They went above and beyond to get a new outdoor unit installed within a day as Texas heat is no joke. Must call for any HVAC work!

 Trustindex verifies that the original source of the review is Google. Huy said the day! We just bought our house and went to go do some deep cleaning before we moved in and noticed the AC was not going below 78F. Turned out the filter needed to be replaced and the AC needed maintenance. Huy was very professional and explained everything to how often he recommended changing our filter to the brand he recommends. We will be scheduling our yearly maintenance with them from here on out. Thank you so much again!

 Trustindex verifies that the original source of the review is Google. Most professional AC company that I have ever done Business with, I had my whole house done a few years ago now by this company and any questions of a mechanical issue a phone call is made or text no matter the time and you will always get an answer. The care that comes is amazing, you are walked through every step of the way with no secrets and you are actually shown the problem instead of just being told. I have recommended this same company to the people I work with the Firestation.

 Trustindex verifies that the original source of the review is Google. Quality fast service. Problem resolved in one day. Thought I needed a whole new system. Turns out it was just a control board that needed to be replaced. Well done troubleshooting and resolving the problem in a timely manner.

 Trustindex verifies that the original source of the review is Google. We had a problem with our AC only cooling the upstairs of our home. Huy was quick to respond and set a time to come by. He quickly diagnosed the issue and had it repaired within minutes. He was honest and knowledgeable. He only tried to get our home cool again for a reasonable price. He did not try to sell us a new unit by lying about the problem, or overcharging us for the repair. So many of the big companies are just sending salesmen to your home rather than a repairman. I would recommend AMS ColdPro.
