Keeping Your A/C Clean on the Outside Can Improve the System's CapacityIf you want to avoid expensive repairs to your air conditioning unit or even a complete replacement, it’s worth investing a little time into keeping the a/c clean. When it’s not maintained in a clean state, those nasty things are possible, and even if it doesn’t get to that point, you are almost certain to lose cooling performance and capacity with a dirty unit. The ‘keep-it-clean’ strategy can apply to both room conditioners and central air conditioners.

Cleaning the Indoor Unit of a Central Air Conditioner

  • Unplug the indoor unit and clean the existing air filter
  • Vacuum up dust and debris from the blower compartment
  • Check for algae in the plastic condensation tube
  • Use a pipe cleaner to clean the drain tube
  • Hook everything up again and restore power

Cleaning the Indoor Unit of a Central Air Conditioner

  • Shut off power to the unit.
  • Vacuum the condenser fins and remove grass, weeds, leaves, and other debris.
  • Unscrew the grill top and wipe the exposed fan clean.
  • If the fan has lubrication ports, add a few drops of oil to them.
  • Using a water hose, spray the fins from the inside of the unit.
  • Return fan and grill to their original positions and screw everything back in place.
  • Allow unit to sit idle for a day, then restore power.

Cleaning a Room Air Conditioner

  • Unplug the air conditioner, remove the rear exhaust panel and clean the fins and coils.
  • Clean out the drain channels with a pipe cleaner or small brush.
  • Remove the front grill and clean the air filter with soapy water. Make sure it has dried before replacing it.
  • Dust off the grill and vents, and after you have made your a/c clean as possible, you can restore power to it.
