I was only told "pay the service fee" The person didn't know how to communicate and only say "pay the service fee" I tried to call and schedule the repairs but they don't awnser or return phone call. I only went with this company because it is through my warranty. I would NOT reccomment this company to anyone. Don't waste your time.

Hopefully I won't need his services in the future but if I do he'll be my first call. Thanks again.

Our AC stopped working during the start of a heatwave, and Kyle was able to get out to us quickly. He was absolutely fantastic--friendly, professional, and incredibly knowledgeable. What really stood out was the honesty. Kyle diagnosed the issue fast, explained everything clearly, and made the repair without trying to upsell us on anything we didn't need. That kind of transparency and integrity is rare these days, and it's exactly why I'll be calling them again for any future HVAC needs. Thanks again to Kyle for the excellent service from start to finish!

He showed up with his partner to access our situation and took his time to troubleshoot. The work required extra work and he personally took that on to work with the manufacturer. He communicated effectively with every step of that process and when we ran into issues, he suggested alternatives. He was able to source and install a new unit for us at a good price and even better timing. He was available to answer any and every question we had. Him and his partner were respectful of our property and situation. In this time of being weary of contractors, he quieted our fears. We plan on using Chris for our next project. I cannot recommend him enough and thankful for making our home warm and comfortable again.

6/2026 UPDATE: After writing my original review a couple of…read moreyears as the time service was excellent and timely, it has drastically gone way down. I called their office 5 times from December 2024 until early the following year to get a proposal for a mini split, never received a return call to either schedule an appointment or provide a proposal as they know my house well. Miscommunication with a contract which took several months to correct when billing an additional amount. However, during the spring service call the billing had not yet been fixed and the technician Angel was instructed to remove my water ordered for my whole house filtration system without telling me. I only discovered it when Angel as to access the boiler room. (This same technician left my hallway walls dirty after I had just had them painted. Fortunately, I was able to clean them.) I knew no servicing was to be done until Winter so I asked why which he responded he was taking the filters that belonged to GMG. I advised that I ordered them and they belonged to me with an adjusted invoice only for the filters and not install. When I had the winter service performed in November 2025, I addressed the duplicity with Joe and the lack of a quote for a mini split. He stated that Andrew was bad at communicating and would share my concerns. I waited to hear from Andrew, nothing so I reached out. An appointment was scheduled and the understanding that the contract would be amended one time only to include the service for water filtration unit which had not been done under the previous contract. No revised contract received and appointment not kept. Since November, I reached repeatedly via text, voicemail and email to receive the corrected contract and then to schedule the spring service, NO RESPONSE! I'm attaching screenshots of the text messages and emails. I then asked to provide me the type of filters so I can get another company to do the work, STILL NO ANSWER with no attempt to address the matter. IT'S A TOTAL LACK OF PROFESSIONALISM; JUST CHILDISH BEHAVIOR! On top of all this, I receive on a regular basis emails to provide a review on a link to them only, not on Google. Well you got your review to your company directly and not on Google. I NO LONGER RECOMMEND THIS COMPANY!!!!

On July 27, 2026 a technician from Flynn-Aire arrived at our home to conduct a yearly maintenance…read moreon our central air conditioning system. We were concerned as we watched the technician and asked him how long he'd been with Flynn-Aire. He answered 8 months. ( for this level of expertise we paid $350) After a cursory check on our system the technician said everything was fine, and he left. Two hours later we went upstairs where to our horror water was dripping from the unit in our attic along the ceiling, onto our carpeting and into our chandelier. After two phone calls Flynn-Aire dispatched a second technician who glued the pipe that had been damaged by technician #1 and told us we would be contacted by Flynn since they had "a Sheetrock Guy" who could repair the damage. And then - crickets. No call from Flynn-Aire. Today is August 7, we have repeatedly called to speak to the owner, Bob Von Hagen, but he obviously has "Colleen" running interference and we have not heard from him. We have pictures to support our statement. We leave the decision on whether or not to use Flynn-Aire for your air conditioning needs to you. Count us as a former client.
