Trusted Heating & Cooling Services in Austin, TX Since 1977

Fantastic service. The tech that showed up (Joey), was on time, professional, and personable. He fixed our problem and presented options concerning our system. He was very knowledgeable and shared that knowledge with me. Great tech! Install team arrived on Friday for replacement of A coil in unit in the attic. Ricardo and Adrian did great job. Another problem arose with compressor. It had gone out. Joey came back and replaced the outside unit, making sure my wife and I had cool air for the weekend. He stayed until he was sure everything was operating correctly. We were pleased with the great service! 9/18, Joey came back to check levels from work done last week and recommend added fixes to get the system to peak performance. He provided estimate of costs and what these improvements would actually do. As always, it was a pleasure dealing with him. Henry came by to perform spring service on Thursday 5/1/25. Very courteous and thorough. He advised of issues with A/C system, and made arrangements to return to install another intake and clean motor. Very good technician, listed all performance checks and was a pleasure to deal with. 5/8/25 Henry & Dylan returned to perform work. They were efficient, on time, performed the job in an excellent manner. Great job! 11/20/25. Eric Suarez came by to check out our heater. He was very efficient and explained what he was doing. Great Tech! Thanks.

Very professional and efficient.

We have been in our house for 40 years and McCullough Heating & Air Conditioning is the only company we have ever used. Always great customer service.

Eric was friendly, only time, explained everything and walked me through everything. I highly recommend this company as every person I interact with is nice, helpful and take their time to listen.

Friendly and knowledgeable. Will use to replace both systems.
