— Cynthia Castillo · Mar 3, 2026 · Google Reviews"JUST GO WITH MCCULLOUGH!! They were $2k+ less than Austin Air Conditioning and Radiant for a 2 ton 2-stage system. Evan is great, doesn't try to give you the hard sell. He provided a lot of information to make me feel good about my decision. Brian and Justin did the install and worked super hard all day to get it done. 2-stage system is awesome!! So much better than our previous 2.5 ton single stage Goodman. Very ha…"
— David Westwood · Mar 6, 2026 · Google Reviews"Evan was absolutely the best helping my older parents decide on an HVAC solution to fit their budget and needs. He showed genuine concern as he patiently explained the options, helped with the financing call, and followed-up as the install crew was working and after. Its hard to find sales people that can be trusted to be fully transparent, but Evan is a rare one. The whole crew worked quickly, were respectful of…"
— Raven Rubottom · Mar 5, 2026 · Google Reviews"Had McCullough install a new unit in December. Initial techs were friendly, people recommended them McCullough provided great guidance on options.

— Neil Wylie · Mar 7, 2026 · Google Reviews"I had my HVAC blower go out and need a blower replacement. I searched and found McCullough as a preferred company through the carrier hvac site and got connected with Craig. Craig was very knowledgable and very helpful. He answered all my questions and in the end I ended up getting a maintenance plan with the company. Heat works great now! Thanks Craig"

— Verified reviewer · Yelp"We had to replace our HVAC system and after receiving a few quotes went with McCullough."
— Verified reviewer · Yelp"We decided on McCullough primarily because of the level of care and detail that Alex took in troubleshooting our issues."
— Verified reviewer · Yelp"They sold me a comfort package for $28 per month for a year which included biannual inspections. I sold my house and they would not transfer the package to the new owner, they would not let me transfer the package to my new house and they would not let me cancel."
— Verified reviewer · BBB"I've had experience with several A/C & Heating companies in the area that didn't meet the expectations I thought I should have experienced. But Heating and A/C with the Georgetown location has met and exceeded my expectations."
