Customers say: True professional

"Michael is hands down the best I’ve ever worked with. He’s exactly who you wish the folks working on your home are like. He has an amazing attention to detail, meticulous, and puts safety above all else. When he realized my boiler couldn’t be put in just yet because of further water damage, he had a water remediation company come in TWO hours to instantly start the process. When he realized my hoses needed updating, he made sure to call it to my attention and had them switched out. For work outside of his scope, he still makes sure to let you know what’s the best for future proofing your home. Above all, he’s communicative, on time, honest, and always there when I have a question. Plus, you can tell he really cares about his craft, and that translates to the job. He chooses the best solution for your situation. My only complaint is I wish he did literally everything else outside of plumbing! I’d want a Michael version of a carpenter, electrician, every day handyman. He‘s that good! "

"Power came back on after the blizzard of '26. But the heat did not come on, and I saw evidence of leaking in the area above the oil heater. Jordan (of Jordan's Plumbing and Heating) called within minutes of my call for help. Jordan and his 1-man crew came over and got things fixed up quickly, despite less-than-ideal conditions. These guys are great."

"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 "

"Two plumbers came out within an hour of calling, fixed several different plumbing and heating issues for a reasonable price, and advised me on necessary maintenance and future work. They were friendly, professional, and efficient, and I will definitely be using them for my plumbing and heating needs in the future."

"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."

"Ryan was very prompt. He took the extra step of checking with our town water supplier when another contractor told us our town water would be damaging to a tankless water heater. He also adjusted his estimate when we received a lower quote for part of the work we needed done. Thank you, Ryan!"
