"Panel upgrade from 100-amp to 200-amp. The old panel was a Federal Pacific which our home inspector flagged as a fire hazard. JJC Electric swapped it out in one day and everything is up to code now. Very professional crew."
"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."
