How to seal off a window unit.

Most window air conditioners come with an accordion style flap attached to the sides to fill the open. However it is important to properly seal them to avoid energy loss. Window air conditioners sit on the windowsill and typically have accordion style fins on either side of the unit that act to seal off the window. The multi pane glass develops condensation or fogginess that can t be wiped off from either side of the window.

Gaps around an unsealed air conditioning unit will allow. The cause is a failure in the edge seal that secures the individual panes of glass. Then lift the window and place the seal under the lip of the window. Unfortunately these are rarely anything close to air tight and the air conditioner itself has to allow air in from the outside by virtue of its construction.

If you don t feel like removing a whole ac unit and sealing off the window the other good option is to seal a window air conditioner for the winter. To fix this purchase some air conditioner foam seal at your local hardware store if there isn t any with your unit. Window air conditioners are an affordable option for home cooling. Re close the window tightly.

The symptoms of failed window seals are easy to spot. Stick the plastic to the tape taking care to seal off the window at every corner and side.
