McMahon Plumbing & Heating has run out of Hyde Park since 1952, and the plumbing license on the wall — #16840 — still checks out active with the state. The company's BBB file shows a change of ownership in April 2023, so "family-owned since 1952," the line that shows up across several directories, may not tell the whole current story. What the reviews actually describe, again and again, is heating equipment. On Google, 541 ratings average 4.6, and the recent ones read less like generic praise and more like case notes: in late June, one customer described a stubborn HVAC problem that turned out to be three separate issues — a dirty coil, a filter nobody knew was there, and a part that shouldn't have been installed in the first place. Earlier that same month, a homeowner in an old Victorian said mini-splits finally fixed a comfort problem that a house full of window units never could, and a broken air conditioner during a heat wave got diagnosed and running again the same visit. In late April, a heat pump installation elsewhere was finished start to finish in three days. By February, a technician checking out a reported heating problem told the customer there wasn't actually anything wrong with it — no upsell, no invented repair. On the plumbing side, a January visit for a new shower head and bidet toilet seat ended with the installers checking their work and leaving the bathroom clean. That same February stretch also shows the one recurring soft spot: a four-star review praised the technician's actual repair but said the front office's updates were cluttered — a complaint that resurfaces in June, when a customer described a confirmed appointment that was skipped entirely, then rebooked more than a week out, with no record on McMahon's end of the earlier calls. Older reviews raise two more things worth asking about before booking: one customer said a water heater warranty wasn't honored the way it was sold, and another said a repair quote came in far above what a past job had cost, with no cheaper option offered. None of that erodes the core of the record — 233 reviews since 2021 across five sources, an A+ BBB grade, and a license that's active — but it points to where the friction lives: not the technicians' hands-on work, which reviewers single out again and again, but the scheduling and office side of the business. McMahon is a reasonable call for heat pump, furnace, and boiler work especially, and for standard plumbing fixture jobs; before booking, get the appointment window and any warranty terms in writing rather than taking them verbally.

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.

The organization of their telephone center leaves a lot to be desired. I had an appointment two weeks in advance. They called the day before to confirm and I missed it. I called back the day of the appointment and they said that the technician is coming but never did. When I called back they claimed that they called me ( they didn’t) and they canceled the appointment. They could rebook me the day after or three days after that. Then the called me back the next day to tell me that their next appointment is two weeks later and have no record of my previous calls. They only have records of the imaginary calls the made but none when I actually talked twice with their representative. And they blamed me for not remembering who I spoke to . So one start for the bad customer service

Ledi was great working around my house. He and his crew would come early and do their job efficiently and in a very outstanding manner. I’m happy to have had Ledi servicing my house. 100%

We recently had mini splits installed in our big-ass Victorian by McMahon. Our house was always freezing in the winter and boiling in the summer. And because of the layout of our place (lots of rooms/no real open areas) we had to have so many window units that it never really cooled anything down. But that's not the case anymore. And we couldn't be happier.<br><br>From the start, everyone at McMahon was just awesome to work with. Our first contact was Steven, who explained everything to us and helped us problem solve for what would be the best solution. After we decided that, Ledi did most of the installation (always with a helper). Ledi does more work in a day than I do in 3 months. He was just great (even our pets loved him). The electricians were awesome. Everyone involved was stellar. McMahon even helped us with the MassSave info we wanted to fill out for an interest-free loan that was available.<br><br>I can not say enough about them. If you are looking to get any heating or cooling units installed, use them. You will not be disappointed.
