MRW Mechanical is a Marblehead HVAC contractor run by Matt (Matthew R. Waldman), holding an active Massachusetts HVAC license and a Carrier Factory Authorized Dealer designation. The company says it handles residential and commercial heating, air conditioning, ductless systems, boilers, and indoor air quality work across a long list of North Shore towns. Its BBB profile and its own website disagree on how long it's been operating — the BBB lists 28 years in business under Matthew R. Waldman, while the company's site claims 15 years. The five reviews on file split sharply by what kind of call it was. When Matt shows up for an emergency, reviewers are enthusiastic: in a February 2023 review, a customer described him responding within an hour on a frigid weekend to fix a dead furnace and clearly explaining what he did, and in a November 2025 review, another described him catching filters a previous technician had left unreplaced for a decade during routine maintenance. Follow-through on installed equipment is a different story. A 2023 review describes a months-long wait to get a company-installed AC serviced, after which the replaced pump kept making noise and the unit began leaking and causing water damage. A 2024 review describes buying two full HVAC units from the company and then waiting more than a year — with repeated "maybe next week" responses — for service on one that stopped working, eventually giving up and hiring someone else. The company's BBB file, which shows it as not accredited and not rated, separately flags a negative customer review specifically about slow response times. For a homeowner weighing MRW Mechanical, the emergency-repair reviews are genuinely good, but the pattern around post-install service and follow-up calls is worth asking about directly — get a clear commitment on response times for warranty or service work before signing a purchase or installation contract.
Excellent HVAC Service and Preparedness! Matt from this HVAC company arrived right on time for our appointment. What started as regular maintenance quickly became a more involved job when he discovered hidden system filters that hadn't been replaced in a decade by the previous Heat Company. Fortunately, Matt was prepared and had the necessary parts on his truck! He seamlessly pivoted and took the extra time needed to complete the replacement on the spot. Highly professional and efficient service!
We have purchased 2 full units and within one year he kept on saying maybe next week I will make it out when we requested service for one of the non functioning units. A year later still has not made it out. We had to find a new company to service and order part which still isn't in. He could have helped us last fall and now still without air becuase of his passive communication and complete lack of ethical service to us.
Poor customer service , quality of service and timely service . It took several months to service out AC that was installed by them . After the service, although the AC worked the pump that was replaced continued to make a loud noise. Noticed the AC was leaking water and damaged our wood floor , had to call another company to fix . The pump was so poorly installed it had come apart therefore allowing water to leak into to our floor . In summary , Matt never took responsibility for his late and poor quality of service .
We called Matt over the recent frigid weekend when our furnace stopped working. He promptly responded to our call and was at our house within an hour, on a Sat no less! Matt fixed the problem in an expeditious manner and clearly explained details on the issue and how to rectify in the future. In a day and age where customer service is virtually non existent, MRW came through in a big way.
Matt is a good guy and knows his stuff.
