Verified record
McMahon Plumbing & Heating is a Hyde Park, Massachusetts-based plumbing, heating, and HVAC company self-reporting service to the Greater Boston area since 1952, part of the Paradigm Energy Services family of companies. When the work gets done, it is consistently well reviewed. Recent 2026 reviews describe a technician diagnosing a multi-cause HVAC problem (a dirty coil, a hidden filter, and a misinstalled part), mini-split installations in an older Victorian home, an AC repair during a heat wave, and boiler and furnace installations, with technicians Ledi, Patrick, and Jack named repeatedly for professionalism and thorough cleanup. Worth asking about before booking: alongside that praise, the written record includes a recurring pattern across 2023-2026 of scheduling and dispatch problems — missed confirmation calls, technicians not showing after a promised time, and being told a job is fully booked during an emergency. A 2025 review describes a water heater failing within its 10-year warranty period, with the company declining to inspect it without a separate fee, and a 2021 review and a 2025 review each describe a job left incomplete with the company becoming unresponsive. For Greater Boston homeowners needing plumbing or HVAC work, the technical reviews are strong, but it's worth confirming scheduling commitments and warranty terms clearly before booking, given the recurring dispatch and follow-through complaints. Massachusetts lists its plumber license, 3622-PL-C, as expired, held by Mcmahon Plumbing & Heating LLC.
“McMahon Plumbing and Heating out of Hyde Park. Mine is just a hot water heater.”
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. 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. 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.
Our air conditioning unit broke down during a very hot stretch of weather …Patrick the technician from McMahon Plumbing came to the rescue and was extremely knowledgeable and professional….the problem was immediately diagnosed and fixed within a timely manner…Patrick explained every step of the process leaving us with a better understanding of the issue….thank you McMahon for having such a knowledgeable professional on your team ….
