May 08, 2025
My low ratings are targeted for the management making decisions behind the scenes, not the service personnel that actually showed up to our home and did the work. The local technicians who installed and have serviced this new unit have been very knowledgeable and professional. My issue with management is due to a failure of the brand new unit within months of installation and their unreasonable position that the warranty did not cover THEIR failure. To rub salt in the wound, the local service manager quoted us a price to repair the issue that was twice the cost of what other local, licensed, HVAC dealers offered to do the work. If one of our other units ever needs to be replaced, it will not be Gagne that we reach out to.

They are all so respectful and courteous. They are very knowledgable. They were so quick to set and keep appointments. It is just so rare to find a company that operates this way in this day and age. The attitude and happiness of the employees is a direct reflection of how the business is run. The team works directly for Gagne and no sub\-contractors are used.

Absolute superb performance from the crew that came out! The two team leads (Attic and Downstairs) were professional, knowledgeable, and ran the team like a well\-oiled machine. Their work was impeccable. The team leads went beyond simply installing the units. Emphasis was made to ensure connections and pipe/cabling runs were neat and orderly, and trip sensors were placed for easy visible inspections. The team leads additionally provided me a detailed walk\-through of the work done as a final inspection. Both maintained a high standard for their own work, and that of their crew. Special kudos as well to the others in the working party. They demonstrated exceptional initiative and approached all their tasks with enthusiasm. They additionally had remarkable high morale and were highly cooperative, always lending each other a helping hand. Top\-notched execution and impressive results from all!
