What homeowners and business owners say about working with our licensed electricians.
"Had three ceiling fans installed in the bedrooms. JJC Electric mounted them securely on new fan-rated boxes, wired the wall switches for separate fan and light control, and balanced every blade. All three run perfectly silent."
"JJC Electric is professional, responds quickly, and pricing is reasonable. They installed a new outlet and light switch for us and the work was done right the first time. Would definitely hire again."
"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."
