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

"We had a great experience the guys know exactly how to take care of any plumbing heating system you might have. I would highly recommend them to anyone that needs there expertise. They do awesome work."

"He called us early morning and by early afternoon we had a new hot water heater. Very professional. I would recommend to all."

"Guy did a great job of diagnosing and repairing our State Hybrid Electric water heater. I would definitely recommend his work."

"was able to complete the job on budget and in the time frame given. took the time to explain to me how to operate the new water heater."

"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."

"Excellent work! Beautiful job mounting the water heater and hooking up all the connections as well as installing a new electrical outlet. Bill came prior to the job in order to create exit piping due to our new siding job that was in process- much appreciated! He spent quite a bit of time explaining the systems we might choose and answering our questions. Very professional and a pleasure to work with. Everything was immaculate when he finished the job. Highly recommend!"

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

"Chris and his team were a pleasure to work with on our hot water tank and boiler replacement project. We are very happy with the results and look forward to working with them again on future projects."
