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 20x25 pleated 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, blower run capacitor, fan run capacitor, contactor, defrost control board, 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 drain pans. Tested the safety switch. Measured a return air temperature of 75.0°F and a supply air temperature of 53.0°F. Additional Actions: Dusted the return grills and thermostat. Checked the thermostat batteries. Restored power to the units. Recommendatio
