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

"An excellent, fast and highly professional service. I highly recommend!"

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"No invoice transparency at Sila Heating, Cooling, Plumbing, and Electrical. I had an appointment on February 16, 2026, to troubleshoot a no-heat issue on the second floor of my home. I was told the repair would be $1,500. Although hesitant, I agreed to proceed because I needed heat. The repair was completed, I paid $1,524.90, and the technician left. I later realized I had not been provided with an invoice, so I called the company directly at 781 438 4114. The person who answered the phone emailed me an invoice. The invoice listed an HVAC diagnostic fee of $69.00, followed by ?HYD 170,? with no price or itemized breakdown provided. I understand that professional services and parts can incur significant costs, it is unreasonable that the part alone could account for the entire charge without any supporting documentation. I respectfully requested a detailed breakdown of the invoice through multiple phone calls and emails; however, the responses I received were dismissive and failed "

"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. "

"great service "

"What I thought would be a simple snaking turned out to be a month long adventure working alongside James (owner) and John at Mac Home Services. Mac Home was excellent. Immediately addressed any issues, worked steadily (even through the holidays!) to resolve pressing plumbing issues, kept me well up to date, were very reasonably priced all things considered. I would absolutely use them again for any plumbing issues. I can't say enough good things about the experience overall. My house was built in the late 1800s and ad-hoc added on to over the years with varying degrees of professional work and Mac work well to fix it all. I never felt like they were having me on (as a young-ish woman owner) or upselling me on anything."

"John “Johnny Rocket” & his associate did an amazing job servicing my home in Winchester. From the moment they walked through the door, they exuded a friendly, knowledgeable and professional manner. They were quick to diagnose the issue in my heating system & worked efficiently to fix the issue on the spot. The entire job was complete in under an hour. I needed a new thermostat & John installed one on the spot as well! I highly recommend hiring these two gentleman for any of your plumbing & heating needs. After the job was complete, they even took the time to talk my son & I about how they enjoyed helping residents in the local Winchester Community. (They are both former Winchester High School graduates.) I would give Johnny Rocket 10 stars ⭐️ if I could. Look No Further! -Emily (Long time Winchester Resident)"
