What homeowners and business owners say about working with our licensed electricians.
"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."
"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."
"Solid generator installation. They sized it correctly for our home, ran the gas line, and programmed the automatic transfer switch. Only four stars because scheduling took about ten days, but the work itself was flawless."
