Best Boiler Service in Boston MA

Trustworthy, honest and knowledgeable.

Incredibly grateful for Frank, who quickly came to my house on a Sunday when I accidentally dropped my ring down the sink. He and a coworker found my ring in no time and he was incredibly friendly and reasonable. I will definitely be calling him again!

Paul is the best plumber in Boston. Very friendly and professionally

Used this firm for many, many years. Great staff.

Next time we have a major repair to any of our plumbing, heating or air conditioning I won’t hesitate and call McMahon plumbing & heating.
They are very professional, knowledgeable and perform repairs that are not only done right but at reasonable price’s. Even during this incredibly hard time they maintained the same quality service while keeping us safe. The tech wore a mask, gloves and kept a safe distance while completing his work. If you are looking for quality service and repair for your home this is the company to call.

Great response and quick service, I had to replaced water boiler ,the company provide 3 replacement rinnai water heaters on demand, installed right away, great price ,quality job, work perfectly, I will recommend 781 plumbing to everybody.

Solid dude, took care of our urgent situation in the middle of a long weekend. We had reached out to several other contractors but Frank was the only one who responded right away to my text message. Would recommend.

Had a leak coming from the upstairs into the basement in Jamaica Plain, ON A SUNDAY!, texted Tony and he responded immediately. When he showed up, he diagnosed the problem, a cracked cast iron drain pipe buried in a wall from our kitchen and cut out the old pipe and replaced it, two hours later all was good. We have used Tony a number of times and we're never disappointed with his work or the price. Thanks!

Rich did a great job helping me out with my broken water heater. He, out of many companies I called, was the fastest, cheapest, and ended up the highest job quality. He’s very friendly and supportive. Highly recommended service!!

I was pleasantly surprised with my experience with Advantage III. I called on a Monday morning, they picked up right away and were very friendly. I was able to get an appointment the next day to look at a water leak I was having in the basement. The plumbers came and identified and fixed the issue within an hour and a half and they were very nice and seemed to be very knowledgeable. Would recommend!

This company has done a great job in everything I have hired them to do over the last several years. You are in good hands if you use them.

No heat fixed no problem Hard worker Very professional

Extremely professional and outstanding courtesy! Not to mention very good plumbing but the former are more important than just knowing how to do the job.
