— Wendell Taylor · Jun 10, 2026 · Google Reviews"McCullough has been a fabulous service partner of ours for many years now, but really stepped up when we were having some very challenging issues with our system. They were able to diagnose and repair the cause with amazing tenacity. I strongly recommend them for great service, and for when the time comes for replacement."

— Haley Townsend Trujillo · May 15, 2026 · Google Reviews"As usual, they were prompt, professional, courteous, and supremely competent. Ryan was neat, well equipped, and on time.

— 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."
