What homeowners and business owners say about working with our licensed electricians.
"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."
"Jamie and his coworker were very skilled, efficient, and friendly. His company installed 5 lights, including a chandelier, and fixed a loose socket on a ceiling fan. Highly recommend."
"JJC Electric did a complete commercial lighting retrofit for our warehouse. Replaced all the old fluorescent fixtures with LED high bays. The space is brighter, our electric bill dropped, and the installation was done over a weekend so we had zero downtime."
