Air Conditioning Maintenance Checklist

  1. Condenser Coil - Clean as required.
  2. Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.

  3. Refrigerant Charge - Checked by superheat/subcooling method (Thermocharging).
  4. A low or high refrigerant charge can easily go unnoticed and increase operating costs up to 30%. An improper charge can cause compressor shutdown.

  5. Controls & Safeties – Inspected & tested
  6. Controls and safeties that do not function properly can increase operation cost and cause other components to fail.

  7. Relays & Contactors – Inspected & cleaned
  8. Worn contacts and loose wire connections can lead to motor or compressor failure

  9. Crankcase Heater – Operationally inspected
  10. Crankcase heaters that do not work can lead to a compressor failure.

  11. Unit Wiring – Inspected & loose connections tightened
  12. Loose connections can lead to a motor, control, or compressor failure.

  13. Temperature & Pressures – Taken & recorded
  14. An accurate record of your equipment’s vital data can indicate potential problems, which can be eliminated. A record will be kept with the unit which may reduce emergency service time.

  15. Capacitors – Tested
  16. Bad capacitors can lead to compressor and motor failure.

  17. Unit Disconnect – Tested
  18. A worn or over-heated disconnect blows fuses and is dangerous.

  19. Lubrication – Application to motors & bearings.
  20. Improperly lubricated rotating equipment will eventually fail.

  21. Belts & Pulleys – Inspected & adjusted
  22. Loose belts and worn pulleys decrease air flow, increase operating costs and shorten the compressor’s life. Belts crack and break with age.

  23. Condensate Drain – Checked to assure it is open
  24. Algae and dust can plug a condensate drain which can cause extensive water damage to your furnace.

  25. Air Filter – Replaced at customer’s option
  26. A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressor’s life.

  27. Voltage & Amp – Draw of the blower motor, compressor & condenser fan motors checked & recorded
  28. Improper voltage and amp draw increase operating costs and can shorten the life of any motor.

  29. Thermostat – Checked & calibrated
  30. Improperly calibrated thermostats cause the unit to run longer than necessary. Every degree your air conditioner operates below 78 degrees can add 5%-8% to the cost of cooling.

  31. Motors – Cleaned & inspected
  32. Dirty motors are less efficient and will fail sooner.
