"Called for an emergency after a burning smell from our outlet. JJC Electric arrived within two hours, found a melted wire behind the wall, replaced the damaged section, and installed a new AFCI outlet. Could have been a fire. Very grateful for their fast response."
"Had a whole-house Generac generator installed by JJC Electric. The crew handled everything — concrete pad, gas line coordination, transfer switch, and the final hookup. We lost power twice since then and the generator kicked on instantly both times."
"Had our electrical panel upgraded to support the new addition we built. JJC Electric coordinated with the general contractor and the city inspector. Good communication and the work was done right. Fair pricing too."
