"JJC Electric has reasonable pricing, is responsive, and quick on getting the project completed. They handled our panel upgrade smoothly and kept us informed throughout the entire process. Highly recommend for any electrical work."
"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."
"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."
