Trusted Heating & Cooling Services in Austin, TX Since 1977

Great service from Dylan at McCullough Heating and AC. They were able to quickly schedule something for me. Dylan quickly diagnosed the problem and cleared a deeply clogged drainage hose. Amiable and professional service. Would recommend.

Great job fixing my air conditioner. Vladimir was a super technician! Being a Comfort Club member sure paid off! Fast service at a great price.

Dillon Revells is the BEST and I would give six (6) stars if I could! My drain line was clogged and it snapped at the attic unit. The threads to the fitting snapped in the attic unit. The sensor turned the system off and I needed help. McCullough sent Dillon to help me get the air going. The problem looked really bad. Dillon explained the situation and the possible costs to repair. It was a difficult looking situation to both he and I. Then, Dillon said he was going to try something radical. He went to his truck, got the tools he needed, and in less than 10 minutes was able to extract the broken threads and fix my broken line issue at minimal cost. Dillon then went outside and dug up my buried drain line and cleared it of the roots that clogged it. My weekend problem was fixed by Dillon in less than a half hour. If you want the best, please ask for Dillon. I am completely satisfied with the knowledge, work, workmanship, and professionalism of Dillon. McCullough is my choice service company and Dillon my choice technician.

Technician Naser Berenji worked diligently to fix a major problem with my A/C system which cause the Ecobee thermostat to reboot repeatedly, thus not cooling my house enough. After several attempts, using various methods, he finally cleared the water drain line which had been clogging and causing the problem. I was very pleased with his work.

Thomas did a great job on our mini-split. He knew what we needed, brought the part, installed it, and made another change that we suggested to prevent water releases from the unit. We are very happy with his work and his professionalism.
