Today I arrived on site and performed a summer tune-up. Here's a summary of the work completed: **Indoor Unit (Air Handler in Attic):** * Verified the unit is servicing the whole home. * Confirmed the filter size is 20x20x1. * Checked the pleated 1" filter; the customer will replace it with their own spare filters. * Observed the indoor coil is clean and in fair condition. **Outdoor Unit (Heat Pump in Back Yard):** * Observed the outdoor coil is in good condition. **Electrical Components:** * Tested and confirmed the blower motor, compressor, blower run capacitor, compressor run capacitor, fan run capacitor, contactor, and electrical wiring are working within manufacturer specifications. **System Components:** * Inspected and confirmed the blower wheel, heat exchanger, secondary drain pan, primary drain pan, secured electrical wires, and ductwork are in good working condition. **System Testing & Adjustments:** * Measured a return air temperature of 72.0°F and
