Will winterizing an window air conditioner improve insulation? Will winterizing an window air conditioner improve insulation?
The window air conditioner is popular with those who only need to cool one or two rooms, rather than the whole house. As the weather gets cooler, these units are used less and less as people want the heat to stay in the room. Winterizing the window air conditioner will improve insulation because even if the unit is not turned on, air will still slip through. Something as simple as placing a cover over the indoor vent will improve the heat retention, and for added insulation, you can cover up the vent from the outside, too.
