Our Story

Since Max and Mike Garrison opened their heating and cooling company in 1972, Garrison & Garrison has been a family business. Back then, we were one of only five companies in Madison County offering service for HVAC systems, and with our four employees, we kept the air circulating in Madison County. The Garrison brothers built our business on the ethics that defined them personally: hard work, honesty, and integrity.A lot has changed in the 47 years Garrison & Garrison has served Madison County, but the principles we operate by have not.

Our Team

Building a Championship Caliber team is nothing new in Alabama, and experience counts. Our team has almost 250 years of combined HVAC experience. Six of our employees, including owner David Garrison, have worked for more than 20 years at Garrison and Garrison. At least two team members have more than 30 years experience with our company.
We invest in quality over quantity, and always strive, through ongoing training, to be the best HVAC team anywhere. A lot has changed in the 47 years Garrison & Garrison has served Madison County, but the principles we operate by have not.
