Does your window air conditioner (AC) have water trickling down its grates? Does the air coming out of the unit seem less cold than earlier in the season?

If so, there could be a problem with your air conditioning filter.

The filters in your AC unit must be cleaned at least once a month to ensure unrestricted airflow.

How to clean it:

  • Turn off the air conditioning unit and use the manufacturers’ directions to assist you in removing the filter from the unit.
  • Inspect the filter for signs of wear and tear. If there are any rips or snags, throw out the filter and replace it.
  • If the filter is still in good condition, vacuum it with the soft brush attachment from your vacuum to remove any dirt and grime.
  • If the filter has an unpleasant odour, sprinkle it with a little bit of baking soda, let it sit for a few minutes, then gently vacuum it up.
  • If the filter is still dirty, use a mix of mild multi-purpose cleaner and water to gently wash the filter with a microfibre cloth.
  • Once the filter is clean, lay it on a towel to soak up the excess moisture. Let the filter dry completely before placing it back into the unit.
  • Never use the air conditioning unit without a filter.
