"We wanted under-cabinet lighting in our kitchen remodel. JJC Electric installed LED strips with a dimmer switch and it looks amazing. They also added two pendant lights over the island. Very detail-oriented work."
"Had a whole-house surge protector installed after lightning took out our refrigerator and TV. JJC Electric put in a panel-mount unit and tested every circuit. Affordable protection and the install took less than an hour."
