Service tech was very competent, and kept me informed. He did not try to upsell me on a service plan, but I asked for one myself.

They perform Fantastic work. McCullough is the hvac installation, service and repair team in austin you can trust. The people from the office personnel, to customer facing serviceman , to sales force, to the company involment in austin area is all ...first class. Better than their white glove treatment is their focus on their customer needs. McCullough customer relations makes for a home relationship where your hvac is in good hands. McCullough for the full life of your hvac system. Its folks like mitchell reeves in service and in alex stevens in customer supprt and sales a great company.Read More...

Buyer beware. I went with McCullough because they were local and their ads and personnel sold me. Paid 15k for a new system and these hacks couldn’t even install it correctly (see photo), they choked the system and won’t bother fixing it. They also ...broke my faucet and I had to pay for a plumber to fix. I can’t get my house to 72 degrees and after a year I can’t get them to come out for the one year maintenance that’s included with a new install. Once they have your money they cut and run. I suggest going elsewhere.Read More...

Our HVAC was on its last legs. . .and luckily waited until after the end of summer to show its unhappiness. We obtained 3 quotes and McCullough was extremely competitive and highly recommended in our neighborhood groups. They replaced our HVAC system ...within the week. But what impressed me, and earned the review, is they sent someone to inspect the work, noted a few issues, and immediately sent someone back out to fix the issues their inspector noticed (which was nothing we would have ever known was an issue). AND THEN they sent us Thank You cookies. Yumm. Would definitely recommend.Read More...

Had a service call to inspect a/c system that was put in last year, part of their warranty program. Technician was very courteous and professional. It was raining outside and he put covers over his shoes to keep my house clean. My little dog harassed him ...the whole time he was there, but he just kept doing his work. That was it. Inspection was completed, he said to call if we needed anything, and he was out the door. It was a quick and unobtrusive visit, and I was very happy with the service.Read More...
