This was a quick visit as it turned out my system was okay. Desmond came out to double check my heat pump after the power outage. I was concerned it was more than flipped breakers. He was here within the timeframe after his call. He was polite, ...professional, tolerant of my dogs and respectful of my property. I’ll keep using McCullough.Read More...

I’ve been through 3 ac companies and didn’t feel satisfied until I tried this company , Mcullough. Their prices are the best in town and my service guy, James was so professional and trustworthy. So many of these companies are salesy and try to sell ...you things you don’t need. This guy was honest and gained my trust. I highly recommend this company with any needs for your AC and heater .Read More...

The service I received from McCullough Heating and Air Conditioning was amazing! Their customer service was prompt at calling me with any updates and ETAs. Then my service tech Joel was fantastic! He was able to safely make it to my place when Austin was ...having a weather emergency. He fixed my heat when we were having freezing temperatures and answered all my questions. I cannot recommend McCullough, and Joel specifically, enough for all of their incredible service.Read More...

I was very happy with every aspect of my recent HVAC system overhaul with McCullough. The comfort specialist, Chris Freeman, was incredibly helpful and continues to be responsive over email regarding follow up questions. The installation team arrived ...exactly when they said they would. They made sure to clean up any drywall or other construction mess before leaving. For anyone wondering, I did a LOT of shopping around on pricing and the different equipment available. After getting five different quotes, McCullough had the best price, the best warranty, the best financing, and the most efficient equipment. Highly recommend them if you need any heating or cooling work. They work extremely well with Austin Energy and they make sure you get all the incentives and financing that may be available through various utility programs. My new heat pump system works great and it's insanely quiet!Read More...
