What homeowners and business owners say about working with our licensed electricians.
"JJC Electric wired our new hot tub with a dedicated 50-amp GFCI circuit and installed the disconnect switch exactly where the inspector wanted it. Passed inspection first try. Professional and by the book."
"Had a whole-house Generac generator installed by JJC Electric. The crew handled everything — concrete pad, gas line coordination, transfer switch, and the final hookup. We lost power twice since then and the generator kicked on instantly both times."
"We needed our entire 1960s home rewired. JJC Electric replaced all the old cloth wiring with modern Romex, installed a new panel, and added GFCI outlets in every wet location. The inspectors were impressed with the quality of work."
