My AC fan went out late Tuesday night. They sent Josh out by Wednesday night. He had it up and running quickly. His truck was thankfully equipped with all the needed parts. He explained everything to me in layman’s terms so I could understand. He was very professional and courteous. He gets a definite 5 stars from me.

Henry was great! As always, McCullough provides the best service for home maintenance services that I’ve found in Austin. It’s not even close to other companies.

Consistent, friendly, but communication lacked a bit from home office. I had been bumped to my second appt. Guy showed up after hours, which was fine, Just expect them to arrive between scheduled allotted time
