"After the last ice storm knocked our power out for three days, we called JJC Electric about a standby generator. They walked us through the options, helped us pick the right size, and had it installed within a week. Best investment we have made."
"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 installed recessed lights in our basement and wired a new sub panel for the finished space. They worked around our schedule, kept the workspace clean, and the finished product looks professional. Would hire again."
