Trusted Heating & Cooling Services in Austin, TX Since 1977

I would highly recommend using McCullough, specifically Jeff. I recently used them for an AC/heat inspection and they inspected my whole system and did a fantastic job. Jeff located an issue in my system and was able to repair it on the spot for a great price. He likely saved me thousands had the issue gone unchecked. Thanks Jeff! Update March 2026: My AC was taking a long time to cool my home, so I called McCullough again. Kyle came out and diagnosed the issue, laid out my options and prices. He did a great job fixing my problem. Glad I called them again. Thanks Kyle!

Today I had my bi-annual appointment with McCullough Heating and Air to make sure everything is working properly and ready for the summer. The technician that came out was Chris Miko. It was my first time working with him and I hope not the last. He was so kind, professional, and extremely knowledgeable about HVAC. He explained everything to me so well and made it very easy to understand because I don’t know much about HVAC. He went above and beyond for me by fixing something that was making my drip pan rust. I would have never known about it because I physically cannot get into my attic. He recommended a hard start kit to elongate the life of my compressor and possibly reduce my electric bill by a little bit. I agreed to it and had him install it before he left. It was very affordable because I’m a member. They give you great discounts when you’re a member. Chris also left my house spotless. He cleaned up after himself really well and was extremely respectful to both my wife and I. My dogs loved him too! I’m hoping that he can be my technician moving forward. I would highly recommend McCullough Heating and Air to all of my family and friends, in fact, I’ve had a few neighbors sign up because of my experience with them. I’d also suggest asking for Chris Miko because he’s the BEST technician I’ve had so far come out and inspect my equipment. His attention to detail was just impeccable and I really appreciated it.

Kyle from McCullough was great. Super attentive and figure out our issue quickly and then had multiple options to remedy.
