  13. Check compressor terminals.
  14. Check compressor amps both start and running.
  15. Check condenser fan motor amps and volts.
  16. Check condenser fan motor capacitor.
  17. Check compressor run capacitor and start kit (if applicable).
  18. Inspect accesses for leaks and all piping for damage and proper insulation.
  19. Inspect insulation on the refrigerant lines and integrity of the vapor barrier.
  20. Inspect line penetration into the home for rodent intrusion.
  21. Overflow protection pan and drain lines (horizontal applications).
  22. Check fan blade for balance.

17-Point Performance Heat Pump Tune-Up

  1. Wash the outdoor coil.
  2. Check the outdoor fan motor bearings and oil if applicable.
  3. Check fan blade for balance.
  4. Check all electrical wiring and connections at the fused disconnect.
  5. Check all the electrical wiring and connections in the outdoor unit itself.
  6. Inspect the coil and tubing for refrigerant leaks or corrosion.
  7. Check compressor amps on start up and run.
  8. Check charge of the system.
  9. Test defrost operations.
  10. Test all capacitors both motors and compressors.
  11. Check drain lines and clear.
