"Panel upgrade from 100-amp to 200-amp. The old panel was a Federal Pacific which our home inspector flagged as a fire hazard. JJC Electric swapped it out in one day and everything is up to code now. Very professional crew."
"Inquired about installing an electric car charger and JJC Electric responded right away and was able to fit me in the next day. The price was reasonable and the installation was done professionally. Very happy with the work."
