Excellent maintenance service. Very friendly and professional folks from McColough. Appreciate the thorough check on our carrier system.

We had three A/C wish list items resolved easily and correctly by Shawn and the team. First, we had a humidity issue in our home and had a whole home dehumidifier installed (we love it). Second, we had the air intake for our unit evaluated and upsized. And third, our original metal ducting had old, deteriorating insulation so we had all the attic ducts re-wrapped and sealed up. We were really impressed with Shawn and the team. They were thorough, professional and helpful. It is obvious that McCullough has a team of folks with plenty of experience to get any job done correctly.

They were great, Makayla is excellent. Very professional and knowledgeable about the systems, and made helpful recommendations for lowering my utility bills on a go forward basis. I will definitely continue to use the company and would like her to be the point of contact for a winter check up.

Sean with McCullough was amazing. He worked hard and showed up fast in this Texas heat. He was very patient in explaining what went wrong. They had the parts available on the truck to save time. Will definitely use McCullough again!

Dillon came on Sun. at about 6:30 pm. He was so nice and spent a lot of time diagnosing my problem. Im new with McCullough and have had a great experience with Henry and Dillon.
