How To Seal A Window Air Conditioner For The Winter

If not winterized, your air conditioner can be a great source of discomfort come wintertime. This is because the spaces between the air conditioner and the wall can let in cool air, which can beat the purpose of using the air conditioner to heat your house. Not to forget that the cold air may damage the wall once it condenses.

For these reasons, you should insulate and seal your window air conditioner to make them airtight. Winterizing window air conditioners is necessary as there may be a space between the window and the air conditioner. And seeing as windows are already a significant heat loss source, not sealing the window AC may lead to an even colder winter.

The best way to insulate window air conditioners is by using foam sealing strips to close off the crack between the window and the air conditioner.

You can also use a cover spread on the face of the air conditioner to prevent heat from escaping through the air conditioner.

Clean your air conditioner thoroughly before you cover it. This will prevent the particles in the air conditioner, and the warm air from growing mold and mildew. You should also use an air conditioner weather seal or plastic to cover the exterior of the AC to prevent heat loss and cold air entering the house through it.
