"After a couple quotes, I decided to go with socal republic. Since day one, these guys made a great impression on me. They were very knowledgeable, had an answer to every one of my questions. Not once did they ever make me feel uncertain or ever question myself with the choice I made. I had the system installed a few months back, and everything is working perfectly fine. Hands down 10 out of 10 service will definitely be calling back for all my future maintenance."
