"John called me to discuss my problem with my generator. After a few questions, John suggested a few quick easy things I could do to correct the problem. After completing the repairs he suggested, the generator operated perfectly. I asked him what I owed and he said no charge and he was just glad I was able to get it running. It's rare to find someone like John in today's business world. Believe me, any chance I get I will refer Farr Service for anyone looking for small engine repairs."

"Unstoppable Electric LLC just installed our Tesla Wall Connector, and wow—what an incredible experience. They were super responsive from the first message, easy to schedule, and showed up right on time. Max is very knowledgeable, professional, and genuinely nice to talk to. He took his time to do everything perfectly—clean, precise, top-quality work with no rush whatsoever. Explained everything clearly, made smart suggestions, and left the garage looking flawless. Pricing was fair and transparent—no surprises. Definitely now my go-to electrician in the area! 10/10 recommend! Thanks again for the stellar work! ⚡️🚗"
