Get matched with top tankless water heater repair pros in Cohasset, MA

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"Can't say enough good things about Whalen Plumbing and Heating. Our tankless water heater was giving us inconsistent temperatures and error codes, and they made the fix painless. They showed up on time, asked what we'd noticed before touching anything, and clearly know these units inside and out. They flushed and descaled the heat exchanger, cleaned the inlet filter, and checked the venting and connections, explaining everything in plain English with no pressure to upsell. They were respectful of our home and left the area cleaner than they found it. Pricing was fair and matched the quote exactly. Since the visit, our hot water has been steady and the unit runs quieter than it has in a long time."

"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."

"Outstanding customer service from start to finish. The plumber was knowledgeable, respectful, and left everything clean after the repair."

"I moved into my 30+ year old townhouse and wanted to replace the furnace before it quit on me. I called a few places and chose Boston Standard because they were the most responsive, explained my options in the clearest manner, and offered to take care of all rebates and credits for me. I was not disappointed! They team was incredibly polite, they showed up when they said they would, and the pricing was exactly as quoted. The guys even wore shoe covers in my house - an extra step I have never seen another contractor of any sort do. Given the experience I also used them for a water heater replacement and dishwasher install, and they service the furnace for me. Their reliability is fantastic and I appreciate how straightforward the pricing is."

"I was very satisfied with NETR. The salesman was knowledgeable and was careful to check for possible obstacles to the use of a heat pump for my application. The installer was very enthusiastic and kept me informed about each step in the installation process. I would recommend NETR for work of this kind."
