"Had security cameras hardwired around our property. JJC Electric ran all the cables through the attic and walls so nothing is visible outside. Four cameras, one NVR, everything works perfectly on the app. Very satisfied."
"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 has reasonable pricing, is responsive, and quick on getting the project completed. They handled our panel upgrade smoothly and kept us informed throughout the entire process. Highly recommend for any electrical work."
