Air Conditioner in a Casement Window 3 Ways to Install a Portable Air Conditioner in a Casement Window

Our upstairs rooms have casement windows (also known as crank out windows), making a traditional in-window air conditioner impossible to install. But I've found three simple ways to set up a casement window air conditioner, to keep our upstairs cool all summer long!Instead of mounting a heavy unit in the window, a portable air conditioner rests on the floor and uses a vent pointed outside. All portable air conditioners need a window, or exit point, this allows the unit to exhaust the hot air from the room.

HOOMEE 400CM Universal Window Seal for Portable Air

All you need to do is put the exhaust hose and window slider in place and then the unit is ready to provide cool room temperatures. Prevent warm air dispensed from your air conditioner hose coming back into your cooled room with the new Airlock. Includes two fabric side covers, capable of covering up to 100% of window gaps* to reduce warm air re-entering the room from the sides, top or bottom openings when the kits is installed.

This is a DIY sizing exercise that gives a good looking effect that can hardly be recognised as vent system. This method uses the window vent insert that comes with the portable air conditioner, coupled with a piece of rigid foam or plywood to block the rest of the window. I was debating screwing the Plexiglass directly to the window frame, but this video shows how one homeowner replaced his window screen with a custom made Plexiglass insert instead.
