"Michael Mabry is extremely thorough, helpful and professional. He walked me through all the work I needed done and explained it very well so I could understand and is genuinely a nice guy! We will be working with him for many years to come."

"Michael of M.A.S.S. Heating & Air is very professional, organized and thorough. Worth every dime spent! I highly recommend this organization for your H-Vac needs and more!"

"He is a scammer. He rigged my system to break down and when he came back out he blamed it on how well he cleaned my system. I will never call him again or recommend him to anyone."

"Michael is a pro’s pro and I can’t recommend him enough. He’s knowledgeable, a strong communicator, and overall just a really good guy. I found Michael by happenstance (via Google) when I needed an after hours service call for furnace issues we were having on a very cold evening. He arrived promptly, diagnosed the issue quickly, and provided me with a detailed explanation as to next steps to get everything running properly. I’m excited to have finally found a “go-to” person and company for our HVAC needs and will be enrolling in MASS Hearing & Air’s routine HVAC service program to keep our system running properly."
