Trusted Heating & Cooling Services in Austin, TX Since 1977

We greatly appreciated the fast and efficient work that Thomas Ischy did at 10 PM to clear our clogged condensation line. He also installed a properly placed clean out port to help us avoid that problem in the future. His thoughtful and appropriate handling of the situation was also much appreciated.

We would definitely recommend McCullough heating and air to everyone. From the dispatchers (Mikayla was great! )to the technicians everyone was professional-caring and on time! Jim and Renee

Makayla was amazing! They were very knowledgeable, professional and fast! 10/10

Tech was very thorough and restored A/C quickly and alway a pleasure doing business with a locally based one.

I recently had Alex come out for a home visit, and I was really impressed. He was professional, personable, and very knowledgeable. He took the time to explain everything clearly and shared valuable insights that helped me better understand my options. It’s rare to meet someone who combines expertise with such a down-to-earth approach — highly recommend working with him.
