How to Clean Air Handler Filters on Air Conditioning Units

An air conditioner's air handler is the fan that blows the air over the cooling coils inside the air conditioning unit and throughout the house. The air that the air handler blows also goes through the air conditioning unit's air filter, removing impurities from the air before it enters your home. However, if your filter is dirty, the air handler cannot work effectively. Cleaning the filter two to three times a season will keep it working well, according to Energy Savers. Usually, only room air conditioner units contain an air handler and filter.

Things You'll Need

• 2 tsp. dish soap
• Cloth

Instructions

1. Open the top of the air conditioner where the vents are located and pull out the dirty air filter.

2. Pull off any dust and dirt clumped on the air filter. If the filter is not reusable, then replace it with a new one.

3. Run a sink half-full of warm water and add 2 tsp. of dish soap. Place the air filter into the sink and scrub the filter with the cloth to remove any dust, dirt and debris.

4. Rinse the air filter off with warm water until it runs clear.

5. Allow the air filter to air dry and place it back into the air conditioner unit in front of the air handler inside.
