Had a great experience with this company. They were fast to come help, reasonably priced and honest. There were a few minor issues after the job was done in which they came right back out in a timely manner to repair.

Our AC was not cooling well, so we called McCullough Heating & Air Conditioning. Scheduling service was quick and easy. Nick arrived on time, identified the issue promptly, and fixed it efficiently. He also explained the problem and gave us useful tips ...for maintaining our AC. Very happy with the service and highly recommend them!Read More...

After a few hiccups regarding the time with the coordinators, it was refreshing to see Alonzo Olivia's go through the equipment and point out a replacement of part.

Outstanding in every way a customer could want or need! The Big 3 for me: Thrifty-Friendly & Quality. am a retired attorney. I research everything, big and small. I knew the issues with my HVAC would be big, so I chose 3 local contractors to diagnose ...and give me bids. One no longer was locally owned. McCullough was not only the best bid, they didn’t try to oversell what I needed to make my system run efficiently. I also liked the representative who came out, and every single individual I interacted with during the process. I was signing a document that needed two witness signatures and the installers even, happily did this for this for me! I started to have noise issues, they were prompt in sending a qualified technician, and flexible about scheduling around me, not themselves. It was discovered that the blower motor was out of line, (a lemon) they ordered the parts, had them the next day and got the job done-right-around my schedule. Telling me what to look for if I had any future concerns or problems. I paid 50% less than the other better known (by heavy advertising) local firm, got 100% customer service, from skilled and friendly technicians, and an exceptional labor and products warranty, without any additional cost. I got the peace of mind knowing that they would be here for as long as I or a subsequent owner needed me. Also, the guys in the photos are actually the guys who come out!Read More...

De’andre came to service our unit on a holiday and made sure that we did not suffer in the Texas heat. It was after hours and they made sure to take care of us. He performed great service and we will use McCullough again and again.
