Performed preventative maintenance on AC system. Customer will change the filter. I inspected the blower assembly, electrical components, wiring, evaporator coil, drain and overall condition of equipment in garage closet. I washed condenser coil thoroughly. Checked and tested thermostat operation, wiring, capacitor, contactor, compressor, fan motor, amps, temperatures and pressures of condenser. Capacitor is leaking, and slightly out of 10% tolerance. Discussed with customer about repair needed. Customer wants to wait on repair. System is cooling properly at this time.
