Today I arrived on site and performed a summer tune-up on your system. Here's a summary of the work completed: Indoor Unit (Air Handler in Attic): Replaced the pleated 20x25 filter. Confirmed the indoor coil is clean and in good condition. Outdoor Unit (Heat Pump on Side of House): Verified the outdoor coil is clean and in good condition. Tested and confirmed proper operation of the blower motor, condenser fan motor, compressor, compressor run capacitor, fan run capacitor, contactor, and electrical wiring. System Components: Inspected and confirmed the blower wheel, secondary drain pan, primary drain pan, electrical wires, and ductwork. Cleared the condensate drain line. Cleaned out the primary and secondary pans. Tested the safety switch. Noted ductwork is in poor condition. System Performance: Measured a return air temperature of 78.0°F and a supply air temperature of 56.0°F. Additional Actions: Wore shoe covers. Restored power to the units. Recommendations: Recommend duct clea
