"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 "

"Excellent. I called Ferris Plumbing on a Thursday afternoon and left a message. Matt returned my call the next morning. After I explained the problem, Matt said he would try to get to me that day (Friday), but he may not be able to. Meanwhile, he suggested not using that toilet. He called later that day and said he couldn't make it, but would be able to on Monday. He called me on Monday morning to confirm that he would be coming and gave me a estimated time of arrival. Matt wasn't able to come himself, but two of his plumbers arrived mid-morning. I explain all of this because Matt's communication was OUTSTANDING. I always knew the status and I knew he would be arriving as soon as he could. His two plumbers were also excellent and efficient. They replaced the toilet flange and gasket, and remounted the toilet without needing to disturb the downstairs ceiling. I should mention that the toilet is the original installation of 48 years ago. The original gasket was completely disintegrated to the point that only few small fragments of it were left. They were also very careful to protect the carpet just outside the bathroom by placing a drop cloth to protect it. Their service and work was EXCELLENT. We are considering remodeling that bathroom and Ferris Plumbing will certainly be our first choice to do the work. I highly recommend (Matt) Ferris Plumbing."

"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. "

"Yes , Mike showed up within a couple hours and completed job quickly."
