An AC window unit is a convenient, compact solution for cooling small spaces. But like any AC, it requires regular servicing and maintenance to continue functioning efficiently. Here is a quick guide to maintaining your AC window unit.

How to Care for Your AC Window Unit

1. Check the Filter

Inspect your air conditioner’s mesh filter at least one a month. If it’s full of dirt, dust, and other debris, wash it with warm, soapy water to remove the buildup and prevent the debris from circulating into your home and impeding your indoor air quality.

Filters could also accumulate mold, mildew, and bacteria, creating health risks. Additionally, it could harbor pollen, dander, and dust, which can exacerbate allergy and asthma symptoms. In general, buildups can impede the unit’s efficiency, increasing energy costs and the risk of a system breakdown, so clean out the filters frequently. 

2. Inspect & Clean the Coils

You should clean your window unit’s condenser coils at least twice a year. Every two months, inspect the coils underneath and behind the unit. If they appear dusty or grimy, vacuum up the grime with a brush attachment and then wipe down the coils with a scrub brush. Removing grime from the coils improves system efficiency and helps combat mold.

3. Clean the Water Pan

To clean the water pan, use warm water, mild soap, and a microfiber cloth to remove the grime and dirt. This will help prevent mold and mildew growth, which can cause musty smells and serious health hazards. For safety, always power down your air conditioner before cleaning the pan.
