"Maffei worked out great, they came first to provide a quote, and then returned a few days later once I was ready to complete the work. Both the front office and field technicians were ultra-professional to work with, and I will not hesitate to hire them again in the future."

"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 "

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

"Awful service, don't use them and don't even consider it!! They will charge you for every minute they are there. I was in traffic trying to get to the property and they charged me for the time they were "waiting". Then they charged me for the time, said they fixed the issue, took payment, and the issue came back hours later. Unacceptable for $500!! What a ripoff! You do not get what you paid for with this company. Look elsewhere and avoid this company propped up on fake reviews."
