What homeowners and business owners say about working with our licensed electricians.
"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."
"JJC Electric wired our new hot tub with a dedicated 50-amp GFCI circuit and installed the disconnect switch exactly where the inspector wanted it. Passed inspection first try. Professional and by the book."
"Excellent service, fixed issue and advised on other issues that I decided to address on the spot. Very helpful."
