"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."

"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"

"Joe was very respectful, personable and patient and explained what he would do and why to ensure our central air would finally work. It took ALL DAY but he installed an exhaust fan in the ceiling with attic ducts to draw out hot air, performed a chemical wash of the condenser, installed a wifi thermostat that required a new transformer and taught me how to use it. I LOVE being able to monitor indoor and outdoor temps on the app and I can see that our summer tenants are using it and that the AC is working great when needed."
