CARJON was started over 25 years ago with one idea in mind: Customer Satisfaction. Over the years we have built our foundation on this idea, providing a quality service that ensures the fulfillment of all of our customers.
This still remains our number one priority at CARJON. In everything we do, from spotless installations to timely service, we go that extra step to make sure you're happy. You can expect the highest level of service from CARJON--nothing short of exceptional. In fact, we've been awarded Highest Level of Customer Satisfaction in New England 4 years in a row and have received the Angie's List Super Service Award the past three years!


We don't need to tell you how much we care about our customers; hear it from them:

CARJON Air Conditioning & Heating, Inc.



Dan, our Carjon service engineer, came to the house as scheduled for our annual gas boiler heating system in March for which we pay only a small monthly fee. The service has been performed since Carjon installed the system sometime in 2012. We have had no issues with our system except for a failure of one of twoTaco Zone Valves needing replacement late in 2023 for which there is a separate fee. A discount was also given since we are on a plan. We are very happy with Carjon’s service and plan.







I have several of heat pump units in my home installed by CARJON around 4 yrs ago. This past week a young man names Seth came to my home to clean them and was very polite.This was his first time coming to do the work here at my home. Very professional, neat and very courteous . When he was done, he thanked me for allowing him to be here and wished his best to us.
