"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."
"Excellent service, fixed issue and advised on other issues that I decided to address on the spot. Very helpful."
"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."
