I purchased an HVAC less than 2 years ago and have had a serious issue with it freezing up. The parts are still covered but not labor. So even though I spent over $12k on this unit I was going to have a hefty labor charge for an almost new system. Enter SHELTON the manager. And boom he takes care of everything and does not charge me labor. McCullough has been taking care of my home and rental for years now and they want to make their customers happy. I highly recommend MCCullough.

Thermostat would intermittently turn off and on. Needed a fix asap and Kyle showed up and got it resolved asap. Also performed a system check while at it. No fluff, true professionals.

The best AC repair experience I have ever had. Easy online scheduling, quick call back to see if I was interested in a quicker appointment, great communication via text throughout, and Zach was phenomenal

We decided to replace and upgrade our three air conditioning and heating systems and started the search and evaluation of the equipment and installers available in Austin. We selected McCullough and hoped it was the best choice., Now the units are installed and everything with McCullough was excellent. The sales contact, the best price quite, the technical recommendation, the installation team and promises made - promises kept have all resulted in 100% satisfaction with McCullough. Save yourself time, money and the the risk of selecting anyone but the best by including McCullough. Thank you McCullough for all you accomplished on time and for the excellent service.
Now in December 2024 I had my first check up and service was as promised, Professional, very thorough, on time and courtesy. So glad we selected and used McCullough.
