However, during the late fall, through the winter, and into early spring, these units are usually unnecessary and also compromise trapping heat inside a home. If your home has an old unit which no longer works, it should be taken out and disposed of properly. If it is in good working condition, then it should be properly insulated in order to keep cold air out of the home.
How to Uninstall a Wall/Window Air ConditionerPlace a large, thick towel on the floor directly under the unit and then unplug the power cord. This will protect the floor from any dripping moisture puddled inside the appliance. Wrap the power cord up and cinch it with string to keep it from dangling and becoming a tripping hazard.

If the unit is simply installed with a wood or metal base and vinyl accordion side panels, removing it will be easy. However, if it’s been installed permanently, it will a bit more work. With the power cord unplugged and wound-up and the towel over the floor, pop-off the front cover and set it to the side. Then, do the following:
- Pull the vinyl accordion side panels out of the window. This might require using a screw drive or power driver to unfasten any retaining screws holding the panels in place.
- Gently pull the unit out from the window. This is where an extra set of helping hands will be needed.
- Unfasten the appliance’s base. It might be supported by a wooden base, metal base, or even propped-up by supports affixed to the exterior.
Now, you can simply close the window or reinsert the pane of glass and store the unit somewhere until it’s needed again.
