"I have been looking for someone to come in and service my standby generator for quite some time. I finally decide to check with Angi's for recommendations. Premier Energy Solutions responded to my query within minutes of my posting. After discussing my system, they informed me that they had a technician who was currently in my area and could come in the same afternoon. Nate showed up early in the afternoon and was able to get my generator functioning within a few hours. He took the time to keep me informed during the process and we discussed my options for going forward with a maintenance schedule."

"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 "
