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

"This was a relatively small water heater repair, and Ryan did an outstanding job. He responded immediately to my request, provided a reasonable quote, was polite, professional, knowledgable, and friendly to deal with. Will definitely hire again if needed."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"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 gas water heater failed on a Friday night. Waking up Saturday a.m. to water in our basement wasn't a pleasant experience. We placed several calls and Quarry Hills was the only company to return our call. Michelle was very helpful with locating the same water heater within a short time frame as the gas heater that failed was still under warranty, to our surprise. She promptly scheduled a tech to our house by 1 p.m. the same day with the new water heater in tow. Seth was very knowledgeable and worked efficiently to get us back up and running. They were straight up with the cost and didn't exceed it when finished with the job. Rebecca followed up with a call to check in on our experience with Quarry and confirmed that they'd forward any warranty information upon receipt. Very professional from start to finish! We won't hesitate using them again for any future issues we may have."

"Boston Plumbing and Heating Solutions responded immediately and was able to come to my house within an hour and fixed the leak. They were courteous and cleaned up after they were done. I would hire again."

"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."

"Same day installation. Called at 10am, 20 year old hot water heater replaced by 3:30 pm."

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