Fontana AC Repair: Control Board and Ductwork Service

Initial System Assessment

A Fontana homeowner requested AC and heating repair on existing equipment. Our technicians inspected the outdoor unit control board, exposed wiring, and interior circuit boards showing alarm codes. The alarm guide manual helped identify relay and connection faults without replacing the full system.
