Mass Mechanical installed our original system, then an upgrade 20+ years later and did a great job! Last night, we lost heat - I emailed them sometime after 6pm. At 6am this morning, I recd an email from Rick saying someone would be there this morning - the technician called at 7:30am to tell us he was on his way and would be here by 8am - and then fixed our system. I wish every contractor was this professional, responsive, and performed the level of quality work!

We needed to replace an 18+year old HVAC system. Went out for 3 bids here locally in Wellesley (The L company, the R company, and Mass Mechanical). Not only was the bid from Mass Mech less than the others, he proposed higher end (more energy efficient) Trane units vs. the other bids and they listened to our needs (vs one of the others who tried to sell us a system that was 2x our target budget, even after I explained to them I wasnt interested). Our home has a half basement, so the work was not fun. The team worked hard, was very communicative and friendly, did an outstanding job, and worked with us to have the system operating the way we wanted. Couldnt be more satisfied and highly recommend them.
