"We had an issue with our HVAC system, not getting good heating or cooling out of it. McMahon were able to figure it out, it turned out to be several things all limiting the HVAC - a dirty coil, a filter we didn’t know existed, a part installed that shouldn’t have been there - until it got fixed. Their people are nice and able to explain what happened for us normal folks. Highly recommend."

About Us

About McMahon Plumbing & Heating

McMahon Plumbing & Heating has spent generations earning the trust of Hyde Park and the surrounding communities, one respectfully handled job at a time. Our technicians show up on time, protect your floors and furniture before they touch a wrench, and walk you through exactly what's happening in your home — no jargon, no upselling, just straight answers from people who genuinely care about getting it right the first time.

Boston's housing stock throws challenges that out-of-town plumbers simply aren't prepared for, but it's our everyday reality. We've repiped more failing cast-iron sewer stacks in triple-decker basements than we can count, replaced brittle galvanized supply lines before they burst inside finished walls, and serviced hydronic boiler systems through brutal New England winters to keep radiators running and pipes from freezing. That hands-on experience with the specific quirks of Hyde Park's older housing means fewer surprises and faster, more accurate diagnoses.

With a 4.6-star rating backed by over 540 reviews, our reputation is built on reliability: technicians like Patrick, Ledi, and Rodney who treat your home like their own, explain every step, and don't leave until the job is done right. Whether it's a burst pipe at 2 a.m. or a full heat pump installation, we're available around the clock because plumbing and heating emergencies don't wait for business hours — and neither do we.
