Winter is coming, so it’s time to put away your in-window A.C. unit
How to clean your air conditioner before storing it
Once your air conditioner is removed from your window, the next step is to clean it before putting it away. There are a few reasons this is a key step. “Dust and debris left on your air conditioner can reduce its efficiency when you go to restart it in the summer,” says Green. “Plus, if you put your A.C. away with water in it, mold could grow and nobody wants to inhale that when you turn it back on.”
The good news: Cleaning your air conditioner before tucking it away is relatively easy. “Simply wipe down the outside of it well and remember to clean or change the air filter,” says Green. “To do this, you can vacuum or clean the coils lightly if you see dirt on them.” You can also use a mild, soapy solution (just mix a bit of soap and water) to clean the filter, says Mitchell. Then, ensure that it is completely dry before packaging it away. If it’s not dry, wipe down anywhere you see moisture and let it sit in a cool, dry spot until you are sure no water is left anywhere.
How to store your air conditioner
Your A.C. has been removed and you’ve cleaned it, you’re finally ready to tuck it away until that warmer weather reappears. If you still have the box it came in, that’s a great place to store it, says Green. Another option? Wrap it in plastic. Either of these options helps to keep out dampness, dust and critters, Green adds. Either way, situate it in the box or plastic like it sits in a window. “This is crucial because any residual fluids from tipping it could damage interior compartments,” says Green.
In terms of where to store your air conditioning unit, you’ll want to be thoughtful about picking the perfect spot. “Select a location that is dry and away from very hot or cold temperatures,” says Mitchell. “A garage, cellar, or even a closet are the ideal spaces. Just stay away from sheds and attics that could get extremely damp or cold in the winter. The worst thing for your unit is moisture, as it can cause rust and electrical damage.”
