By the end of fall, you will need to think about storing your window air conditioner so it will not get damaged from any dirt and debris that may accumulate during the winter. Here are four tips for storing your window air conditioner over the winter.
1. Remove the Air Conditioner Unit
If you do not want to keep the air conditioner outside, remove it and put it into storage in a shed or garage where it will be safe over the winter.
2. Clean the Exterior of the Air Conditioner Unit
This may seem like an obvious thing to do, but you will be surprised how many people do not clean their air conditioning unit. In fact, even if you live in an environment that does not have winter (like anywhere along the equator), you will need to clean your air conditioning unit once in a while.
To clean the outside of the unit, use a sponge or a cloth to wipe the outside of the air conditioning unit and the windowsill it is attached to.
3. Clean the Inside of the Air Conditioner Unit
Cleaning the inside of the unit involves a bit more work, and may require a professional air conditioning service professional to go over and clean it. However, if you want to have a go at cleaning the insides of the unit, start by removing the air filter and lightly spray it with a hose to remove any dirt from the filter housing. Wash the filter in warm and soapy water before letting it dry. After this, lightly hose down the unit and scrub down the dirt where required. Using a vinegar-and-water solution can assist in cleaning the dirt and stains. Use a vacuum's brush attachment and an old toothbrush to clean the fins.
4. Use a Winterizing Cover
A winterizing cover is important to help keep your air conditioner in good condition during the winter months. A thermal winterizing cover can be bought at any home improvement store in several different sizes, so you will need to measure the dimensions of your air conditioning unit before you buy it. This winterizing cover is important because it helps protect the air conditioner's exterior from dirt, debris and insects that were blown by the wind.
5. Cover it with Foam and Plastic
To completely seal the air conditioner from anything that may get inside the unit, use insulating foam. Think of it as a project to try and extend your storm window. Use the insulating foam between all openings, and cover those sections with pieces from a corrugated box before covering it with a winterizing cover. You will also want to put insulating foam on the top and bottom of the inside of your window sash. After this, you will want to cover the inside of the window with a plastic sheeting kit. However, this last step cannot be done if you have old and cracking paint on the window frame.
