Nick Day with Garrison and Garrison came out as a call back on another techs previous regular maintenance call. There was an issue that was not discovered, Nick, with some investigation diagnosed our problem, which was a small leak in the air handler coil. Now that we know what the issue is and our options are we can make an informed decision. Nick was very thorough and professional. Thanksread more

I just got fantastic service on my 3 year old HVAC unit with a leaking suction line from a badly brazed joint. The original installer wanted over $2500 for the repair. Garrison & Garrison did the repair quickly for less than $500. Wow, what a difference! I have definitely switched to Garrison & Garrison for all my HVAC needs. Kody did a fantastic repair job and best of all he did a great job of explaining everthing he was doing.read more

Rudy was the technician who came out this morning to perform my semiannual maintenance. He was punctual, polite, and efficient. He explained all the actions that he performed, and even changed my filter for me (it’s in the ceiling so not the easiest thing for me to do). He also put on those little booties every time he came into the house, so he wouldn’t track anything in from the attic or outside.Great service, as usual, from Garrison and Garrison. I will continue to use them for my HVAC needs.read more

This was my first time using Garrison and Garrison for semi-annual HVAC maintenance, after having purchased a new system from them in 2025. The service work was performed well and the Technician, Roberto, answered all questions to my complete satisfaction. I paid for the annual maintenance service which will carry me to next March/April 2027.read more

Was recommended by a friend after a lightning strike when one thing after the other kept dying around the house including our AC. Alex was extremely professional, courteous and knowledgeable (but not above calling for assistance when needed). He and team members were in and out of my home for two weeks as new things went kaput but gave me very fair pricing (another company quoted me THREE TIMEs what they did), didn’t ding me for more house calls and always came before noon on the same day. Last team, Roberto and Collin were also of the same caliber. Thanks Garrison and Garrison – hope we don’t see you for a while!!read more

Terrell did the spring time maintenance on our two A/C systems today. I can’t be more pleased with his professionalism, attention to detail, and his thoroughness in every cleaning and system check he performed. He answered all of my questions in detail.. Arrived on time as scheduled & advised ahead of time his arrival on site. I truly received my moneys worth today. I have been using G&G for over 30 years – I highly recommend this company.read more

Yesterday, Beau Garrison & his crew came out and installed a new downstairs HVAC system. They did a great job in making sure the install was done right. The duct work and cabling was neatly installed & the old unit hauled off & the site cleaned up. Afterwards, Beau was very patient in showing my wife & me how to connect our phones to our new smart thermostat. Today, Ronny came out to check out my upstairs unit to verify that it was also in good working order. He showed great attention to detail in carefully going over the inside and outside components. Very impressed with him & his knowledge. He fixed some issues that another company’s HVAC person had messed up. I’d highly recommend Garrison & Garrison for their quality work and great customer service.read more

I’ve been a G & G customer for over 10 years now and have been extremely satisfied with them always.Today, February 24, Roberto came to do my regular maintenance which was fortuitous as my unit acted up through the night and was not blowing hot air.Roberto spend 2+ hours at my house troubleshooting the problem until he had it all figured out and then repaired. After getting that done he did the regular maintenance and went on his way.He was friendly, professional, explained what he was doing every step of the way, and voila! The house is warm again thanks to him. And at no cost to me. This was the second time my unit acted up and the last time I was charged the maintenance call which I did not have a problem paying, but the problem wasn’t fixed. It is now thanks to Roberto.I always recommend G & G whenever I know anyone needs their service. After Roberto being here today I hope I get him for the next service.Kudos to him!read more

My wife and I have used Garrison & Garrison for almost twenty years. They are always professional, reliable and their prices are reasonable. After many years we had a problem with the inside coil and they fixed it under warranty and did a great job! Their Technician Ronnie was at our home today to perform a semi annual inspection service to our HVAC unit and really went out of his way to answer my questions and like all the techs throughout the years was very friendly and informative. They are a great company to use.read more

Roberto, Juan and Jonathan did a great job installing our replacement heat pump. It was a very difficult installation because of space for the air handler and they took the time to do it right. They cleaned up everything, pointed out a problem we had with a shut off switch related to our generator so that we could get that fixed and we were very pleased with the service we got we have been a customer of Garrison and Garrison for 40 years.read more
