How do you
make an air conditioner fit into a window that's just too small?
Samuel: Beckley, WV.
Delete the old window, put it away for safe keeping. Build up the empty
space layer by layer. Most folks will mount their unit in the middle in
an attempt to be symmetrical. I did this last year and missed out on
not having a window I could open.
The picture shows an alternate method of tucking it into the corner,
which provides more stability and just enough room for a small
window/door on the side. Building up the space in layers allows you to
use up pieces of scrap material, which keeps the price of this project
under the cost of a cup of coffee.
