Most air conditioners can be installed in narrower windows with out the side panels that come with the air conditioner. Refer to the model specific Installation & Assembly instructions in the user manual for the minimum window dimensions.
If installing in a window larger than the included hardware supports consult with an a/c window installer for instructions. Most hardware stores do carry generic window installation kits for larger size windows.
