From duct-free split systems and heat pumps to thermostats and humidifier installations, you can expect only the best HVAC installations to keep you and your family comfortable in your home.

No matter how well an HVAC system was installed, there might be times where you will need a professional HVAC contractor to repair a faulty thermostat, wiring issues, leaking ducts, or any number of other problems you may encounter.

Maintenance Services

One of the essential, yet most neglected, HVAC services is system maintenance. Your AC and heating units are responsible for conditioning the air and filtering out allergens and pollutants to help keep you and your family comfortable and healthy, so proper care and servicing of the equipment is a mandatory practice. Bringing in the trusted local HVAC contractors at Gagne is an excellent way to identify problems, perform quick-fixes, and deter costly repairs.

“Gagne installed new HVAC units for me in the Spring. They did an awesome job and the units are great. If I had known they would make such a difference in the comfort of our home I would have done it year ago. I have recommended Gagne several times and everyone has been equally happy.”

"The lady I talk on the phone to schedule the technician was brilliant. She promptly understood my issue with the furnace at the basement and scheduled the technician to come and troubleshoot it right away. The technician was courteous and knowledgeable. He identified the issue and we are now waiting for parts to complete the repair. Great service. Thank you"

-Juan P.

“I had a great experience with our Gagne technician. He was on time, very knowledgeable and even went back up into my attic to help me label some vents when he was done and about to walk out the door which was really helpful! I’ve been using Gagne for years…always a good experience.”
