When your home doesn’t have centralized air conditioning, window AC units are a great alternative. However, these units are not maintenance-free. To get them to work most optimally, you’ll need to clean them on a consistent basis.

Start With the Filter

One crucial component of your window AC unit that needs to be cleaned frequently is its filter. You should be washing your filter on a monthly basis. After unplugging your air conditioner, you’ll need to remove the front panel and take out the filter. Use a vacuum to clear away any solid debris like dust and hair. You can wash the filter with warm soapy water to get rid of all the remaining debris. You must let your air filter completely dry before you reinstall it. Reinstalling the filter while it’s wet can create the perfect environment for mold and mildew growth when you turn your air conditioner back on.

Clean the Internal Components

Next, you’ll want to clean out the internal components of your air conditioning unit. One of the best ways to do this is to purchase a can of condensed air that will allow you to use pressurized force to remove debris stuck on the aluminum fence inside of your unit. While you’re cleaning, it’s a good idea to softly bend any fins back into place.

Inside your window air conditioning unit, there’s going to be a drip tray. You want to remove the water from this tray and any debris that is stuck in it. Additionally, you want to ensure that the drain is clear and not stuck full of debris or hard water scaling.


Do an External Wash

With a mixture of water and a mild detergent, you’ll want to wipe down the exterior of your AC unit. This includes the grill as well as the top and sides of the unit. Make sure that you dry off your unit with a cloth, paying special attention to small corners where the water can pool. You’ll want to give it a good hour or so before you turn the unit back on to ensure that it is completely dry.
