How Long Should Cooling System Components Last?

The following are rough guidelines:

  • A quality air conditioner that is maintained annually will last 15 to 18 years. Excessive noise and vibration can alert you to possible pending replacement.
  • Refrigerant might need to be periodically added, depending on your system. If you find you’ve added refrigerant year after year, you might be looking at a bigger problem.
  • 1″ air filters must be changed monthly.  Thick media air filters must be changed twice per year.
  • Thermostats go out of calibration and periodically need to be replaced.
  • UV lights should be replaced every one to three years, depending on the manufacturer.
