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.

We started using McCullough for our HVAC needs after another company installed our heat pump and made many mistakes. McCullough fixed the problems and has consistently given us superior service at our seasonal checkups. James, Brian, Alvin, Dereck and all of the technicians we have dealt with have been knowledgeable, efficient, and a delight to work with. We will never use anyone else for our HVAC needs.
