I try to avoid using the air conditioner, but I do turn it on a few times each summer. I recently acquired a new unit from a friend, only to find that even with the sides pulled out, it was about 8" shorter than my window. When I went to my local hardware store, the sales associate had a great solution…

He suggested I fill the space with cardboard wrapped in aluminum foil, and seal it with duct tape. Besides filling the gap, the foil also acts as a reflector, reflecting the heat back outside. I took it a step further, and used some reflective insulation I had left over from another project.
