Real reviews from real customers — see why property owners trust our electricians.
"Our 1970s fuse box was long overdue for an upgrade. JJC Electric replaced it with a modern 200-amp breaker panel. They labeled every circuit, replaced the meter base, and passed inspection on the first try. Should have done this years ago."
"Replaced an old light fixture with a ceiling fan in our master bedroom. JJC Electric reinforced the junction box, ran a new switch leg for the fan control, and had it done in about two hours. Looks great and works perfectly."
"One of my circuit breakers started arcing. I turned that line off and called JJC Electric on Yelp. Jamie sent me a message at 11 that same night, we set up a time the next morning. He fixed the issue quickly and professionally. Great service."
