Our 2 year old heat pump quit cooling this summer and we called Garrison and Garrison who installed it. They diagnosed the problem quickly and gave us a fair estimate. My wife and I thought we had bought the extended warranty but could not immediately find the paperwork. When Mr. Sherrill returned Monday to do the work he let us know that he found the records and we would be covered. Mr. Sherrill took it upon himself to dig through the records for us, he completed the work with his teammate quickly, and he left a note in the system for the future that we did have the warranty. Very happy we went with Garrison and more

I called Garrison & Garrison for a free second opinion on a cracked heat exchanger. Bob came out and diagnosed the problem, answered all my questions, and even showed me the cracks in the heat exchanger when I asked to see them. David from sales came out right away and explained my options to me and walked me through the paperwork to purchase a new unit. I was given a flat price including a 10 year parts and labor warranty, and duct repair even though the extent was unknown at the time. Two days later, Bill and his installation showed up exactly on time to install the new unit and repair my duct work. They were courteous, friendly, and professional. They even cleaned up some old lattice fencing that had fallen down around my old unit. I highly recommend Garrison & Garrison and will be using them for all my HVAC needs in the future.Update: I called for a check up in Oct 2020 because my heat wasn’t working. Terrell arrived that same day, gave me a call 30 minutes in advance, and was extremely polite and friendly. He took care of everything and there was no charge thanks to my warranty. Very satisfied customer!read more

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
