New England winters are both beautiful and unpredictable. Here at Key Heating & Air Conditioning Inc. we have over 25 years of experience installing, repairing, servicing and maintaining residential heating systems to keep you warm.


Having trouble with your furnace, boiler, geothermal or heat pump? Our heating system technicians are factory trained to handle all problems big and small. 


We also install brand new heating systems or replace your aging one with a new energy efficient system. We are committed to recommending and helping you choose the best home heating system based on your specific needs. Our home comfort advisors can provide you with a free home analysis and custom proposal, as well as educate you along the way. We also offer great financing options with credit approval to help you get the job done.


We don’t sell fuel here at Key, so we are unbiased in our recommendations, and we are truly able to focus on the ideal home heating equipment for you.
