Best Tankless Water Heater Replacement in Boston MA

As a real estate agent it is important to be able to recommend vendors of all types that I can count on to do the job for my client. This company has not only exceeded all my expectations for my clients, but done so in a timely and professional way. Cannot recommend them highly enough!

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!

We have used McMahon Plumbing & Heating for years. They always do a great job never had a problem with them. The workers who come to the house always do a great job they are knowledgeable and personable.

I can’t say enough great things about Frank. He does excellent work for excellent prices. I am a homeowner and landlord, I could not do what I do without his help. He always answers the phone and solves my problem ASAP. He has helped me out so much over the years I run even non plumbing issues by him for his guidance and he helps me there too. I highly recommend him for all your plumbing needs.

Rich replaced my hot water heater. I was very impressed. He did an excellent job, was very personable, and stood by the quote he gave me. I could tell he loves what he does and wants to make sure it’s done the right way. He even helped me over the phone when I first called to make sure my old hot water heater was properly turned off. I would call him for any plumbing needs!

I recommend these guys 100%. When I call Joe the owner or the secretary that’s the beginning of my plumbing problems being resolved….every time!

As a property owner I appreciate and need that responsiveness.

Matthew D. provided excellent service installing a new dishwasher, gas range and kitchen faucet. He was on time, gave each projected the attention and expertise it required, treated each project individually and gave it A+ service. Each installation was done very well and worked beautifully. Matthew was polite, pleasant, neat and communicated well throughout the process. I can't recommend Matthew more highly!

We used True Blue Plumbing and Heating for a new central air conditioning unit over the summer. They were extremely responsive throughout the whole process and did excellent work.

The repair that was required, was done so with great swiftness, and the plumber who did so was awesome. He was honest, and I would not hesitate to call him back, and would recommend him to anyone. Thank you

Tom saved the day by quickly replacing a failing toilet. He was fast and responsive and did a high quality job!

Best Commercial Plumbing/HVAC System Installation Company in Boston MA Operating With Maximum Efficiency! I'll trust them as sub-contractors for any major commercial/industrial construction project I have in the future!

We were not getting heat in a back bedroom. Tom came out and found out the previous folks must have had kid(s) who threw down all sorts of stuff down the ductwork. He cleaned our furnace and fixed our problem with a very reasonable price. Highly recommend!

Rich is a lifesaver! I called early on a Sunday morning with a leaking water heater. He came by within an hour to check that we’d contained the leak temporarily, and came back to fully replace the tank early the next day. He performed quality work and was very kind and easygoing. Will continue to recommend Boston Water Heaters to friends and family!

Two other plumbers had no idea what was causing my heating system to fail. After wasting money on service calls, GPH had it figured out within an hour of inspection and fixed within a day. These guys are experienced and reasonably priced. My go-to from this point forward.
