Performed preventative maintenance on AC system. Customer changed the filters this month, so I left him some filters to use. Inspected the blower assembly, motor, electrical components, evaporator coil, drain and overall condition of equipment in utility room. Drain had a small condensation leak that I wiped up and then reapplied glue to. Washed condenser coil thoroughly. Inspected the condenser coil, compressor, capacitor, contactor, fan motor and operation. Checked thermostat operation, wiring, amps, temperatures and pressures of condenser. System is cooling properly within manufactured specifications at this time.
