Today I arrived on site and performed a summer tune-up. The system is currently working properly. **Indoor Unit (Package Unit):** * Observed the indoor coil to be in fair condition. * Noted the filter size as 8x30. * Checked the pleated 1" filter; the customer has spare filters and will replace them. **Outdoor Unit:** * Observed the outdoor coil to be in fair condition. * Verified the drain line is strapped. **Electrical Components:** * Tested and inspected the blower motor, condenser fan motor, compressor, blower run capacitor, compressor run capacitor, fan run capacitor, compressor start capacitor, contactor, and electrical wiring; all are working properly within manufacturer's specifications. **System Components:** * Inspected the blower wheel, secondary drain pan, primary drain pan, and electrical wires; all are in good condition and working properly. **Measurements:** * Measured the return air temperature at 69.0°F and the supply air temperature at 108.0°
