"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."
"Jamie and his coworker were very skilled, efficient, and friendly. His company installed 5 lights, including a chandelier, and fixed a loose socket on a ceiling fan. Highly recommend."
"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."
