"JJC Electric handled the full electrical for our garage conversion — new sub panel, outlets, lighting, and a dedicated circuit for the mini split. Solid work. Only minor issue was a scheduling delay but the actual work was excellent."
"JJC Electric installed recessed lights in our basement and wired a new sub panel for the finished space. They worked around our schedule, kept the workspace clean, and the finished product looks professional. Would hire again."
"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."
