Vlad was very knowledgeable and helpful and explained what needed to be done. He recommended that we get CO detectors and where to get them, After the repair, he helped us with another unrelated problem.

McCullough air conditioning has been our provider for years. We’re moving, and the inspector discovered an issue with one of the Plenum’s. McCulloch came right out and inspected it and then replaced it within a week. Harry was knowledgeable, professional, and very pleasant to work with.

We're incredibly happy with our new HVAC. I would not trust any other to sort out my HVAC system. Their experience and abilities by far exceed the rest out there... Also, they are one of the last 'local' major HVAC outfits in ATX (bonus)

Was referred to McCullough by a friend who has used them for years. We just had a new system installed by another firm and our new rep found quite a few things that he adjusted that have made a difference already. Our old firm got bought by a PE firm and service was more about speed than quality. We have found our new preferred HVAC provider.
