"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."

"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 "

"Workman was excellent. Did not take advantage of me. Told me to try WD 40 on my lock before purchasing a new lock and it works fine now. Fixed my oven door, and my freezer was working when he arrived. He told me not to over crowned or block circulation and to call if it stopped working again. I was very satisfied with this company, would recommend them highly and would hire them again."

"Ryan is a great plumber. Very happy to hire him for my plumbing job, including changing all the hardware for the tub shower and vanity sink. He was professional and his quote was fair. He provided his plumbing license and insurance information quickly. It’s helpful that he also guarantees his work for one year. I will definitely use his service again for future plumbing needs and would highly recommend him to others. "

"We had Minutemen do extensive work at our home, including both HVAC and plumbing, and the experience was outstanding from start to finish. They handled multiple projects for us and every part of the process was professional, organized, and high quality. The team was knowledgeable, responsive, and took the time to explain the work and our options clearly. What really stood out was their attention to detail and the pride they took in their work. Everything was completed carefully and neatly, and they made sure the systems were working perfectly before finishing. They were reliable, respectful of our home, and communicated well throughout the entire process. It’s hard to find contractors you can fully trust with large projects, but this team absolutely delivered. We’re very happy with the results and would highly recommend them for both HVAC and plumbing work."

"These guys are a horrible private equity roll up... go by 3 different names to disperse the terrible customer reviews. They promised to be out first thing in the morning after we had a full day without heat (and three small children in the home). One hour into the eta window I got calls from two different dispatchers who clearly are not in a centralized location, telling me the roads are not clear. The roads are clear. These guys suck. Do not engage with them. "

FAQs for water heater repair or service projects in Cohasset, MA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
