"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 "

"He was very professional, he did a great job."

"Fast and friendly. Reasonable price."

"Cody and his crew were amazing-- we had a complicated issue that required multiple visits and coordination with the city's engineers. Cody was professional, knowledgeable, and as dedicated to getting the job done right as if it had been his own home. His quotes were accurate and competitive, he and his crew were on time (and often stayed late!) and kept the work area clean and safe. We will never call anyone else!"

"Excellent! they actually arrive early, they found the tank without me being there and they did the work and the person is very friendly, they explained everything they've done, the person is cooperative and the price was good!"

"They arrived early. That’s usually a good thing. But I had to go out quickly before they arrived. They didn’t call 30 minutes before arriving like they’d promised. So it was hectic off the bat. Not a big deal. But later, when it was determined that I needed some repair work on the system, they were difficult to reach. They took my number down wrong at first. But even after calling several additional times with my correct number, they still took several weeks to get back to me. I hired them because they market themselves as a full-service septic maintenance/repair/engineering company. I got the sense that they didn’t want to deal with me."

"They were excellent. I had a septic pipe leak into my basement and garage. They came out immediately. They were professional and kind and fixed the issue and the price was very reasonable."
