If your window slides from side to side, you’ll need a slider/casement air conditioner. This type of installation involves the following:
The air conditioner sits on the windowsill. The window to the side slides over and supports the air conditioner in place with a bar. Since slider window air conditioners vary in height, a filler panel is used to keep outside elements from entering your home. If you have a crank-out window, a slider window A/C is a great solution. The entire pane will be removed, a piece of plexiglass will fill the space, and a hole is cut for the A/C to be installed.
