"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 "

"Ray quoted a replacement natural gas steam boiler at a price well under what both Boston Standard and Sila quoted me. Well under meaning close to 20% less. Ray is very responsive by phone and he shows up when he says is going to. Ray had done maintenance on our old boiler prior to this complete replacement. He actually performed maintenance on our old steam boiler, unlike when Boston Standard and Sila did maintenance they would simply turn it on and made sure it fired up. When Ray came and did maintenance after the 4 years we had both Boston Standard and Sila maintain our boiler he disassembled and cleaned out the incoming piping, replaced the glass water tube level, added a skimming drain, skimmed the boiler, etc. The prior 2 companies never did that level of work and it was in bad shape. In addition, not many technicians have knowledge of steam boilers these days even though they are still quite common in New England homes. Back to the new replacement boiler that we just had completed. Ray did a fantastic job on the installation. I really couldn't ask for better service. He was timely and efficient (we had our heat back on the same day), explained everything thoroughly (usually multiple times for my benefit) and has called and come back to check on everything a couple times since the installation. He's really gone above and beyond. We have 1-pipe steam radiators and he understands the intricacy of steam quite well. Ray also did all the plumbing when we had our kitchen renovated. He was our contractor's choice for a plumber (which is how we found Ray) which gave him that extra credibility knowing other professionals use his services. I would not hesitate to use Ray again in the future and recommend him to everyone."
