"The guys at MassAir made having to get new central AC units installed, repairs on older units, new vents and ductwork, etc., actually a pleasurable experience! It is a family owned business, and I found Joe and his son Michael to be a real pleasure to work with. They are an extremely professional, proficient, knowledgeable, honest and hardworking team, and I trust them with any HVAC related projects that I have in the future. I 100% recommend giving these guys a call for your HVAC needs! -Mike Vedder"

"My a/c circuit breaker kept tripping upon start-up of the unit. I read the positive reviews about KN, so I requested a quote and Kevin responded with a text within an hour. He was even able to come the same day and spent 2 hours to thoroughly inspect and test the various components of the system (including the connector in my attic), and replace the hard start. Kevin was very professional and thoroughly explained how the system functions and what he was doing each step of the way, which I really appreciated. I would highly recommend Kevin for your HVAC needs!"

"Eric showed up for the estimate on time and called back a few days later to check in. Eric and his crew replaced my central air today. They showed up on time and got right to work. The install went quick and it looks professional and neat. Will recommend him to anyone needs HVAC."
