"*AVOID THIS COMPANY: We had an extremely disappointing and concerning experience with H L Bowman and strongly caution others before using this company. In 2019, we hired them to replace an outdoor spigot/hose bib and copper plumbing, which cost $309. That installation ultimately failed within a few years due to what a technician on a recent visit confirmed was an improper initial installation. Fast forward to our recent service call: a technician came out, diagnosed the issue, and quoted us over $700 to replace a simple hose bib with no additional parts required. After questioning the price, they ?discounted? it to $600. Feeling uneasy about the pricing, we asked them to stop the work so we could get a second opinion.

"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.

"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 respectfully requested a detailed breakdown of the invoice through multiple phone calls and emails; however, the responses I received were dismissive and failed "

"Very knowledgeable and professional."

"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!"

"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."
