I needed someone to help me quickly resolve a condensation issue that was detected by our buyer's inspection. McCullough was able to come out the same morning and do an inspection. My technician Ryan was able to quickly find an unsealed joint between the duct and drywall at the moist register and sealed it for me. He completed this service and thoroughly inspected my HVAC equipment (per my request) while tidying and cleaning behind himself everywhere he went. I paid less than $150 for the entire service. I told him I was happy to pay more for the value of service I received but he politely declined. Ryan could not have been more professional and polite. A massive thank you to McCullough and Ryan!

Another company told me I had to replace my entire unit because they couldn’t figure out why my drain pan was holding water constantly…obviously it’s the main line…the other company cleared the lines (but didn’t) and said that the only solution was replacement of entire system quoting changes in refrigerant.
McCullough came in and saw that the drain line was blocked from inside unit because of faulty installation leaving materials in unit. So the cleaned the line correctly and opened the plenum to see the issue. They redid the lines and added floats that were faulty and ‘snaked’ the lines rather than some CO2 cartridge cleaning….completely comprehensive. They fixed it and saved me money…A LOT OF MONEY - didn’t need a replacement just someone who can diagnosis a problem. They charge a fair price and instantly earned a customer for life.
If you are looking for honesty….and a fair price - this is your people. Oh, and they took pictures and videos and explained everything as well as share it with me…professional, knowledgeable, and fair pricing. Highly recommend with absolutely no doubt….

Thanks to Mathew Santos and McCullough!
We had an excellent experience with McCullough heating and air. Our 7 year old Carrier Infinity AC system broke down and it was still in warranty. Another company whom I had been using quoted - 6 to 8 weeks for repair and we started considering replacing the system.
I called McCullough for estimate for new system and their representative Kelvin suggested checking for repair first and setup us for repair service call.
Mathew came for repair, he checked what parts (compressor, inverter board) had to be replaced, got them from Carrier the same day and installed them and fixed the system in the same day (and much less than the cost that other service was quoting).
Thank you so much - Kelvin (for honest suggestion)
Thank you so much - Mathew Santos (for fixing our AC in just one day)

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!

Understand that I am classified as elderly by age. My house is 75 years old. I have lived here 32 years. Within 5 years of moving in, I bought a new Goodman system which lasted > 20 years. I bought this new system last September. So when my HVAC unit was no longer functional at 2:30 PM on Saturday, I started making calls. First I called the company that installed the unit September of 2025. They only had a recording that said they'd be open on Monday. I had had a problem in April. That company did respond and cleared out the condensation conduit, a problem which I'd never had with the old system. The unit worked fine until Saturday. So I started calling HVAC repair companies. Another company responded that they could come between 8:00 PM and 12 midnight. They responded and indeed, discovered it was the clogged condensate conduit. However, he was unable to definitively locate the terminus of the line, which was understandable. Nor was he able to clear the conduit. He recommended the condensate pump. He, too, did satisfactory work. I lost track of all the calls I had made, so when Josh said he was on the way on Sunday ~6 PM, I thought I would get his opinion. He agreed that the problem was that the condensate wasn't draining. He was able to clear the conduit and get the HVAC system functional again. He, too, recommended the condensate pump. He, like the previous technician, explained how it works and what it does and what the installation would entail. I appreciate his willingness to answer all my questions. The system has been functioning ever since. But I check it frequently. I look forward to getting the pump installed.
