Trusted Heating & Cooling Services in Austin, TX Since 1977

Mccullough always comes thru for me. Purchased new Carrier about 4yrs ago from them and they handled all the warranties Austin permit and rebate. Plus Electric company set up. Setting up a service call they give you an all day window but service will call a few minutes ahead to give you a heads up. I do wish they could at least say morning or afternoon tho when i schedule.

Mr Sanchez showed up timely and was most knowledgable about my HVAC system. He found problem with sensor almost immediately and was able to provide estimated cost of replacement. He gave me an outlined plan of action and later followed through. Very professional and helpful. Thanks, James!
