We're Built To A Higher Standard

Winner of American Standard’s Building a Higher Standard Award in 2022

Garrison and Garrison believes in always doing the right thing, whether it’s installing a new HVAC system in your home, repairing an existing one, or just being of assistance in any way we can with honesty, courtesy and hometown service.

In 2022, we were awarded American Standard Heating and Air Conditioning’s highest honor, the Building a Higher Standard Award. This award is given annually to only four dealers nationwide, and we’re proud to be the one of the recipients of this year’s award.

We owe our thanks to American Standard for selecting us but just as importantly, the great people of Madison County and North Alabama for trusting us to help keep them comfortable for more than 50 years.
