Performed preventative maintenance on Package Unit. Cleaned reusable filter for customer. Inspected blower assembly, motor, electrical components, evaporator coil, drain and overall condition of equipment. Washed condenser coil thoroughly. Also inspected the capacitor, contactor, compressor, fan motor, and condenser coil. Checked thermostat operation, amps, temperatures and pressures of condenser. System is cooling properly within manufactured specifications at this time. Package unit is aging, and I do recommend customer plan for replacement in the next few years.
