Trusted Heating & Cooling Services in Austin, TX Since 1977

The service was professional and thorough. The service representative, Makayla exceeded my expectations for great service. Thank you.

I have a service plan with McCullough HAC, and it is the best investment I have made for my HAC system. The AC stopped working, and with just one call, I got a next-day appointment. Matt, the technician, arrived right on schedule, made a diagnosis, and fixed the unit; we were up and running in no time! Thanks, guys! UPDATE: Second visit, same as above. Every technician is professionally trained (It shows!) Talking with confidence on the subject gives me peace of mind. New UPDATE—Summer 2025: A same-day appointment is settled! One of the benefits of having a service plan is the ability to rely on professional technicians to resolve our issues. Call McCulloch HAC! Fall 2026: Charles came for the fall-winter check of the HAC system. As always, a detailed and accurate check of the system is conducted, anticipating potential issues that, if not addressed, may result in significant expenses. Highly recommended!

Brian came out and did a thorough and expeditious review of my heating system before the winter weather comes. Thank you Brian thank you McCullough.

Excellent, prompt response, thorough inspection. Repair & inspection technician, “Clayton” deserves recognition for his courteous & professional service.

Eric was super amazing, knowledgeable and extremely polite and professional!! He went above and beyond to sort out the issue that was occurring with our HVAC system! I will definitely recommendation him and McCullough to my friends and neighbors!
