There are two main reasons you shouldn't leave your air conditioner (AC) window units on the windows during the winter season, especially if your area experiences freezing temperatures. First, the unit risks getting damaged because it isn't designed to operate under such conditions. Secondly, they can also increase your heating energy consumption by allowing heated air to escape. This is why you need to store your window AC during the winter. Here are three tips for the storage:
Detach & Clean the AC
Removing the unit from the window isn't too complicated, but it is relatively heavy and it's best to have a helping hand. Remember to turn off the unit and unplug it before detaching it from the window. Don't forget that it will probably leak some fluids so you shouldn't place it on anything you value (like your bare carpet).
Next, you need to clean the AC so that is it ready for winter storage. For the outside surface of the unit, this is as easy as wiping it with a soft cloth. The air filters also have to be cleaned, especially if they have been in use for some time without cleaning or replacement. However, this part of the job is best left to the professionals.
Cover it Up
Once the AC unit is clean, prepare it for storage by covering it up. Otherwise, the resources you spend on cleaning the unit will go to waste when it is attacked by debris and insects during storage. Suitable cover materials include things like heavy duty trash bags and tarps. However, it is best to pack the AC unit in its original box if it is still lying around.
Place it in a Cool, Dry Place
Once the AC unit is wrapped up or boxed, it is time to find a suitable storage place for it. Make sure the storage place is cool and dry; you don't want mold and mildew to infect your beloved unit. Therefore, don't take it to the basement, unless you are sure your basement will remain cool and dry throughout the winter. Remember to keep the unit upright during storage; storing it in any other way may damage the compressor.
Keep these tips in mind the next time you want to keep your window AC safe for the winter. This is also a good time to service your HVAC system; consult services such as Hospitality Heating and Air Conditioning Inc to help you with the service.
