"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."
"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."
"Had three ceiling fans installed in the bedrooms. JJC Electric mounted them securely on new fan-rated boxes, wired the wall switches for separate fan and light control, and balanced every blade. All three run perfectly silent."
