EFR Mechanical

Four Google ratings. That is the whole public verdict so far on EFR Mechanical, a Waltham shop whose own site describes plumbing service alongside commercial HVAC-R maintenance, repair and installation. The Better Business Bureau puts the company's start at 2019, its headcount at six, and has accredited it since November 2021 with an A+ grade — a mark tied to the bureau's own standards rather than to anyone's finished job. That profile carries no customer reviews and no complaints. Procore's unclaimed listing files the same company at 102 Clematis Ave as a plumbing specialty contractor working both commercial and residential sectors. What written attention exists comes from the trade press, not from homeowners. A June 2021 MassPlumbers profile introduced Ricardo Souza as the owner of what it called a growing plumbing and heating contractor, and reported that Local 12's business manager had told him the union would back him if he started a shop. In May 2025, High-Profile Monthly counted EFR Mechanical volunteers among those at the Charles River Earth Day cleanup. Two things worth settling before you call. The BBB lists two Massachusetts Board of State Examiners of Plumbers and Gas Fitters numbers for the company, 4464 and 16771 — a directory's entries, not something confirmed against the state board, so ask which covers your job and who holds it. And the BBB profile describes plumbing and HVAC services to commercial customers, so confirm they take residential work of your size. This is a shortlist candidate on the strength of its standing in the trade rather than on what past customers have written, because almost none of it has been written down yet.
