I called these guys for a second opinion and they quoted me thousands less than the first guy! They are the only company I call when needing help.

They maintain my boiler which is very old and just last year replaced my water heater for me. They do excellent work with fair pricing, and the guys are very knowledgeable. I would highly recommend!

Humidifiers and dehumidifiers help you maintain the optimal humidity in your home to protect your home and health. A humidifier adds moisture to the air to boost humidity back to comfortable levels, while a dehumidifier extracts moisture from the air to reduce the humidity level. Both can help in eliminating respiratory ailments like asthma and chest congestion.
Living in Central New York, and especially Oswego County means that you're facing harsh winters! Having a Generac Generator gives you peace of mind that you'll never lose power.

Thank you for your technical assistance with my Gibson gas furnace giving a "False flame or gas relay shorted" code and no heat. Problem was isolated to a faulty resistor on the control board. Replaced the circuit board and furnace is now heating. Your worker can now be deployed sooner to someone else that has no heat! I enthusiastically recommend your company to anyone.

I had our furnace replaced. Start to finish, everyone was courteous, concerned for my schedule, flexible, the price was right and they cleaned up after themselves.
Highly recommend them

Chuck, Dan, Jesse, and John were amazing! They were super professional and willing to answer any questions we had during the process. The quote matched the completed price and was very reasonable. Everything turned out better than expected and I would recommend anyone do business with them.

Tyler showed up on time. He was very respectful and professional. He didn't have the part available but he came back at the end of the day. He replaced the part and thanks to his diligence...we have heat again. We would highly recommend him. Hard working young man with great work ethic. Chiasson heating are lucky to have him. Thank you Tyler!!

We can’t speak highly enough on the service provided by your business. Your quick response to our heating needs after hours and the quality of work on our furnace repairs and the installation of our new furnace is second to none. Thank you Chuck for your explanation on options and your knowledge. You and your crew were professional and courteous and went above and beyond while you installed our new furnace.
