How To Clean A Window Air Conditioner

Since the back of your window air conditioner is exposed to the elements at all times, it should come as no surprise that occasional cleaning is required to keep it running at full capacity. Here are some simple tips for cleaning your window air conditioner.

Clean the Filter and the Exterior

The two most basic tasks involved in maintaining a window air conditioner are cleaning the exterior and the filter. If the outside of your air conditioner is clean, less debris will fall through the vents to clog the internal components. Wiping down the air conditioner with a soapy rag to remove dirt and plant debris is all that is necessary for cleaning the exterior.

Your air conditioner filter can be found just behind the front panel. This filter is responsible for removing pollen, dust, and other allergens from the air that is blown into your home. When the filter gets dirty, indoor air quality will be reduced, and the air conditioner will have to work harder to circulate air, reducing its efficiency. To clean the filter, remove it from the air conditioner and use a vacuum hose to suck out dust and dirt. A low-pressure garden hose can be used for deep cleaning if necessary, but be sure to let the filter dry before reinstalling it.

Clean the Evaporator Coils

The evaporator coils in a window air conditioner can be found just behind the front vents. When your air conditioner is running, refrigerant is circulated through these coils to cool the air that comes out of your air conditioner. If the coils get too dirty, it can prevent the temperature exchange between the coils and the air, causing the coils to freeze up.

You must remove the casing of your air conditioner to access the evaporator coils and clean them. Remove the bolts that hold the outer casing in place and lift it off of your air conditioner, and then use a vacuum hose to pull dirt and dust out of the coils. Follow this up with a foaming coil cleaner purchased from your local home improvement store. Spray the foaming cleaner onto the coils, allow it to set for the time specified on the can, and then use a cloth to wipe down the coils.

Window air conditioner cleaning is not difficult, and regular cleaning can significantly increase the lifespan of your air conditioner. Use these tips to keep your air conditioner running smoothly for as long as possible.
