How to Clean the Coils

Window air conditioners typically work by circulating indoor air through metal coils located on the outside of the unit. These coils are either in direct contact with the window or mounted on a bracket that rests against it. Over time, dust, dirt, and other particles can accumulate on these coils, which can lead to poor cooling performance and even AC unit failure. Here are four tips for cleaning your window AC coils:

1. Remove the unit from the window: Before beginning any coil cleaning, you first have to remove the AC unit from the window. This may require removing screws or hinges that secure it to the frame. Once removed, you can use a vacuum cleaner and/or a hose attachment to remove all debris and dirt from the coils.

2. Use a degreaser: If degreasing is not an option because of surface damage (e.g., rust), then you can use a commercial coil-cleaning solution such as Guaranteed No-Fault AC Coil Cleaner. Simply spray a small amount of cleaner onto a cloth and wipe down each coil until clean. Be sure to rinse off all product residue before reinserting the AC unit into its bracket or back into your window.

3. Use a brush: If degreasing is not an option due to surface damage, then you can try using a brush instead. Wet one end of the brush in water and apply pressure while scrubbing across each coil until clean. Again, be sure to

Tips for Cleaning the Coils

Window air conditioners have coils that get dirty over time. Here are some tips for cleaning them:

-Before cleaning, turn off the AC and disconnect the power cord from the unit.
-Wash the exterior of the coil in a bucket of water using a nonabrasive brush. Make sure to get into all the nooks and crannies.
-Rinse well with clean water and dry off completely.
-If there is grime or dried sweat on the inside surface of the coil, use a hose to spray water onto the coil from several directions. Agitate and rinse thoroughly with clean water.
-Apply a thin layer of CRC anti-static spray to one side of a clean, lint free cloth and wipe the coil clean. Apply more spray if needed to avoid sticking. Be careful not to remove any dirt or debris from around the edges of the grill.
