Window-mounted AC units can keep you comfortable without significantly increasing your energy bills. They come in many sizes ranging from 5,000 BTUs to 25,000 BTUs. Although repairs should be performed by an HVAC contractor, basic maintenance can be handled by homeowners. Here’s what you need to know.
How to Maintain a Window AC
1. Clean the Filter
Window AC units have washable foam, carbon, or mesh filters. They are easy to remove. However, check your AC manual for removal specifics. Inspect the filter for damage. If you find any, replace it right away. Damaged filters allow dust, insects, and allergens into your home. If it’s in good shape, clean it with mild dish detergent and warm water, and set it out to dry before placing it back into the unit.
2. Check for Insects & Animal Nests
Unplug the device and remove the outside cover. Next, look for signs of small animals or insect nests. For example, wasps and bees will often make their homes inside of AC units. Vacuum them out and place the outside cover back on the unit.
3. Clean the Condenser Coils
Generally, the coils are located in the front of the AC unit. Remove the front plate, un-mount the AC unit, and take it outside. Vacuum the condenser coils with a soft brush attachment. Check the coil fins, and if any are bent, use a fin comb to straighten them. When purchasing a comb, check the user manual for the coil fin teeth count. Coil fins can cut you, so either have an HVAC contractor do the job or use leather gloves when cleaning.
