I’ve been using Garrison & Garrison since we built this house 25 years ago. They installed the systems then and have maintained them since. Much has changed in Huntsville in 25 years, but not Garrison & Garrison’s quality work & customer service. That’s why I still use them for all my HVAC more

Terrell Turner the service technician was outstanding! We called Garrison & Garrison to obtain a second opinion because another company, our previous service provider, stated our unit had to be replaced due to damage. Terrell reviewed the entire system, took pieces apart to ensure there were not issues, and conduct a very thorough inspection. He provided expert advice – was professional and engaging – and was clear he was not going to recommend additional services or replacement if it was not necessary. I was deeply impressed and because of Terrell, immediately signed up with Garrison & Garrison to be our service provider. He should be recognized for his superior more

Your service tech was just here to perform a semiannual system inspection. The tech’s name is Ronnie, and he has performed inspections for us in the past. We could not be more pleased with his service. Ronnie is professional, technically knowledgeable, courteous, and caring. On the inspection today he noted, then confirmed that we had a gas leak. Something we would not have been aware of, had he not told us. Employees like Ronnie speak well for company; he is one of the reasons we have remained a Garrison & Garrison customer over the more

Dexter came to fix our thermostat, located in the front part of the house. He detected a faint gas odor and located the source at our gas heater at the back of the house. It had been improperly installed (8 months prior). He was also able to fix that. Extremely skilled with exceptional customer service. We couldn’t be more pleased!read more
