"Was professional and efficient. Handled a walk-in closet fixture that was flickering. Offered lifetime warranty. Light working well now. Would use again."
"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."
