"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 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."
