Real reviews from real customers — see why property owners trust our electricians.
"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."
"Needed a 240-volt outlet for our EV charger. JJC Electric came out, assessed the panel capacity, ran the wire through the attic to the garage, and had it done in half a day. Clean work, fair price, no mess."
"Our 1970s fuse box was long overdue for an upgrade. JJC Electric replaced it with a modern 200-amp breaker panel. They labeled every circuit, replaced the meter base, and passed inspection on the first try. Should have done this years ago."
