Garrison & Garrison is the only business I call for the two HVAC systems in my home. I’ve been burned by others after my original guy retired. I’ve been lied to and ripped off. I’ve had rodents chewing signaling wires, another wire physically pinched by a housing reinstalled 90 degrees off position, spiders building webs in condensation drip pipes (blocking flow), fuses installed in an improper sequence and a failed motherboard controlling electrostatic filters (thankfully covered under warranty).If my husband and I had hired G&G to replace our two units a decade ago, I suspect that we would have had fewer problems, but we didn’t know what we know now, and new products often have issues that only become apparent over time. No installation can be perfect but I can point to two different specific errors in my upstairs unit. One error can’t be addressed without replacing the entire system, and the other error was fixed by G&G years later. We kept trying to work with the original installers, but they refused to admit that they had installed systems that were too large. I was told that high indoor humidity levels were to be expected because “This is Alabama”… like I hadn’t already lived here for ten years and had never had 95% humidity issues when my old units were functioning. At this point, I have to install a whole house dehumidifier to avoid sealing my crawl spare and put one there (the other option to address the oversized units). Stupid, right? A/C is supposed to dehumidify! You’re probably guessing by now how infuriating I found it to be treated like I can’t understand basic physics.In contrast, the techs G&G sends out don’t treat me like I’m a fool.😅 I like it that they send only one guy instead of two. IMO, a second guy only increases labor costs, and usually accomplishes little because they are “being trained”. They admit when they are stumped (proof of professionalism!), call for support and do their best to solve my issues. It’s not easy to go up and down (what is in effect) four stories to check continuity between the paired units which cool my upstairs. I appreciate the tech checking for warranty coverage and explaining how I could bypass a faulty filter system feature if I wanted to save money and still have filtration.This is all on top of the fact that G&G techs are just nice guys, period. I think I’ve met them all by now! I’m looking forward to getting my HVAC units finally functional this summer.read more

Highly recommended and extremely satisfied. Beau and Brent did an outstanding job installing the new system answering all of the questions l had. They explained everything and cleaned up afterwards to my satisfaction. I have to admit this entire venture from David Johnson,who deserves 5 stars himself, to the completed job was very professional. They let you know that they really care about you being satisfied. Keep up the good work it’s a rarity during these times.read more

I very highly recommend Garrison & Garrison for any HVAC needs. We were having issues with our heating system which were quickly and very professionally resolved by Ronnie Head. Ronnie’s extensive knowledge of the industry answered my questions and set my mind at ease. This is a great example of how a customer service business should be run. I’ll look no further if I ever have another heating or a/c problem!! 🙂read more

Above and beyond! The crew just left my house. My unit went out Thursday before the sleet storm. They haven’t been able to get on the roads until today.They arrived and installed it just as the rain started for the next storm. Thank you Garrison and Garrison, so much, for getting us heat for the next round of winter weather!Update: still AWESOME service.My old thermostat caused an issue. In the process, they came to my house 4 times making sure that we heat and it was fixed. In the end, we finally changed the thermostat and all is well.The custom service is real. They never put me off a day or two… I called, and they came. Mrs. Jones we are going to make sure and make this right.Wonderful company!read more

Garrison and Garrison came to our house to give us a second opinion about our HVAC unit. Not only did they not charge us for coming out to inspect it, they fixed the problem the next day for over $500 less than the other company quoted the job! The other company told us it would take two weeks for them to get the part in and do the work. We were so pleased with the work Garrison and Garrison did and with the personality of the technician who came to our house. We will definitely call them first the next time we need help.read more

My furnace had to be replaced as temperatures dropped and the streets iced. The technician had to walk up and icy hill to get to my house. My furnace was replaced as quickly as possible during the winter storm and they provided excellent service.

I had no heat with a forecast of sub-freezing temps. Garrison and Garrison got a tech out right away to diagnose the problem. He was great – courteous and knowledgeable – and although they didn’t have the part for an immediate fix, he was able to get it the following day and get it installed. My heat came on instantly!Kudos to Antonio for correctly diagnosing what was needed and working to get the part asap. I definitely would call on this company again.read more
