My apartment has double hung windows, but they are quite narrow (~19.5 inches at the screen, 22 inches at the opening). I'm currently using a portable air conditioner, but I'd really like to use a standard window fit model.
There are a variety of compact AC units available whose physical dimensions are smaller than the opening, but state they require a minimum window size larger than I have (23 inches, for say a unit that measures 18.5 inches at its widest point). Can these units be made to fit, by say not installing the side panels? Anyone tried this and made it work?
