Easy Steps to Protect Your Window Air Conditioner During the Cold Winter Months

Inflicting winter weather can inflict significant damage on your window AC unit and make it difficult for you to use once summertime comes around. Fortunately, you can take several simple, precautionary steps to protect your unit for winter. For example, you can switch off the power to your unit and then make a winter cover to protect it from wet, cold weather. Covering your air conditioner window can prevent cold air from entering your home and save you money on your electric bill.

To cover your window air conditioner for winter, begin by switching off the power to the unit and then to the outside condensing unit. Then, remove any debris around the unit, such as leaves and weeds, and clean your AC with a water hose and soapy water. Vacuum the interior and the exterior of the unit to remove dust, hair, and lint. Once it’s completely dry, use a foam or rubber pipe insulation to protect exposed exterior pipes from the cold, wet weather.

To make a winter cover, you can use a tarp, cardboard, or both. Attach the cover to the window using rope or bungee cords, if necessary. If you use cardboard, make sure it has a few drain holes to prevent any water collection. Sealing the window around your AC unit may also help to keep the cold air out and save you money on your electric bill.

You can also use crumpled-up newspaper to insulate the window. Place the crumpled paper around the window to act as a buffer to both cold air and heat. Secure the newspaper in place using adhesive tape or tape loops. Newspaper also works great for insulation around the interior and exterior components of your AC unit.

Before the colder months arrive, double-check and see if your window AC unit is clean and protected from the cold winter. Make sure to inspect the window, seals, and connections for any gaps or cracks. Applying caulk or weather-stripping to these areas may assist in keeping the cold air out and the hot air in.

Finally, protect your air conditioner from the freezing temperatures of winter by making a custom-made indoor or outdoor cover. Clean out any debris, attach insulation around exposed components, and ensure your window is properly covered. By taking these few steps in preparing your window AC unit for winter, you can make sure your AC will be working hard in the summer blooms!
