"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."
"JJC Electric is professional, responds quickly, and pricing is reasonable. They installed a new outlet and light switch for us and the work was done right the first time. Would definitely hire again."
