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

"Given the fact that having a water heater fail is never a fun experience, Joe and his team did such a fantastic job of making the situation so much better for us. Honest, hard working, fair pricing, and quality work. They were honestly a lifesaver given my wife was recently pregnant and being without hot water is not an option. They came out quickly for the estimate and there the next day for the install. Professional and courtesy and all around great team. Highly recommend!!!"

"Had mike and zach out to replace my gas water heater. They were on time, professional, and courteous of my home. They even wear shoe covers and use drop mats to make sure the floors dont get dirty! Excellent customer service at a reasonable price"

"I had a heating issue and contacted Scott, he was there quickly and had me up and running in no time. He was very detailed oriented and I wouldn’t hesitate to hire him for a job again. "

"Brian and his crew were great. Brian came out and gave a great estimate for everything I needed. He was very responsive via email as we worked to schedule a time for his crew to come do the work, which was mainly water tank and heating system maintenance. Brian brought Jim promptly and explained the work. They then pointed out a couple of things that they recommended replacing, one they just included in the original cost estimate and another they added on due to additional parts being purchased. Jim was very thorough and professional and, by all accounts, did great work. I’ll be using Heavy Doody for all of my future plumbing and heating needs!"

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"They were very prompt and made sure my HVAC unit, tankless hot water heater and fireplace were all in order prior to the sale of my condo unit. Although it was much more than $99 I had expected to spend, the maintenance work was needed."

"The repairs were professionally completed; however, I thought the cost was a bit excessive for the amount of time and materials required."
