Need to Repair Your A/C or Heating System?

Upfront pricing. No hidden fees or sneaky upgrades.

When the weather turns in Austin, there's nothing like a well-functioning system to keep your family comfortable. Our goal is to help you stay cool in the summer and warm in the winter.

When your HVAC system slows down or malfunctions, you need a professional to restore your system to working order right away. Not only to keep your home comfy but to extend the life of your HVAC system and manage your electricity bills.

An inefficient system is often a symptom of failing components. Get your AC system checked and fixed now before the problems cascade into larger, more expensive ones.

Common Heating repairs we address for Greater Austin homes include:

  • Strange noises coming from the air conditioner or heater
  • AC struggling to keep your home at a comfortable temperature
  • Utility bills are increasing every month
  • House not cooling or warming up when the system is on
  • Your AC system is frozen with visible ice
  • Uneven temperatures; some rooms are too cold, other rooms are too warm
  • The system comes on and off too frequently
  • Indoor air temperature doesn’t match thermostat setting
  • Blower does not turn off – always running
  • AC or Heater over 10 years old

All of these problems are fixable.

We moved into our new home, tried to update our thermostat to a smart one and the AC stopped working. I called McCullough and they were not only out within 3 hours of me calling, they fixed the problem within an hour and had us up and running in a cool house again.

I definitely recommend calling these guys up if you need HVAC service!

I am very impressed with the quick professional service I received from Tony and Oscar. They answered all my questions and even cleaned up before they left. The financing they offer made buying a new system really affordable. Another bonus... My electric bill is less than a third of what it used to be, I'm so pleased to have the lower bills. Y'all do great work...Thanks!
