Austin’s Local HVAC Company & Plumber Since 1977

I previously gave a good review to McCullough. Unfortunately I have to reverse that review. AFTER spending close to $3000, the repair didn't even last a month. We are back to square one with a new estimate of $6000 plus to fix my home AC. At first the technician who worked on the AC unit said it was hard to find the spot where the refrigerant was leaking. After supposedly fixing that leak, another leak was discovered by a 3rd McCullough technician when called to check the AC unit less than 5 weeks later. Now the price is $6000 plus with no mention of the poor workmanship done previously or the money that I paid. There isn't even any warranty for their service. I have no intention of employing the services of this company anymore.

We had a fantastic experience with Thomas from McCullough Heating and Air Conditioning! We were in a real bind with our AC, and he came through for us. He was honest about what actually needed to be fixed and didn’t try to upsell us on anything we didn’t need, which is hard to find with home repairs. He communicated clearly the whole time and explained everything so we actually understood what was going on. We’re really grateful we found someone this trustworthy. Highly recommend McCullough Heating and Air Conditioning and Thomas!

We can’t say enough good things about McCullough Heating & Air. We purchased two new HVAC units from them last year, and from the initial consultation and installation to their outstanding follow-up service, they have exceeded our expectations every step of the way.

After weeks of 100+ degree temperatures here in Austin, one of our units developed an issue due to a manufacturing defect. One quick call to McCullough was all it took and they responded immediately. When the first repair didn’t completely solve the problem, they had another crew out the very next day. They continued sending experienced technicians until they identified the exact cause and made sure it was fixed correctly.

What impressed us most was the level of customer service. We truly felt like we were their only customers. The communication, follow-up, and commitment to getting it right were exceptional. They stood behind both their work and the manufacturer’s warranty without hesitation.

If you’re looking for a company that genuinely cares about its customers, we highly recommend Al, the owner, and his incredible team. Whether you need a new HVAC system, routine service, repairs, or warranty work, McCullough Heating & Air delivers top-notch service with professionalism and integrity. They have earned our trust, and they’ll be our HVAC company for years to come!
