However, it is not recommended that you do this because the vent system is what removes the hot air from your home.

I considered drilling exhaust ports into the walls to evacuate the hot air, but utlimately went for installed split systems which are in a different league by every measure. Now that your Plexiglass is installed and weatherproofed, all that’s left is to attach the exhaust hose to your Plexiglass and enjoy the cool air. It’s a very simple process that should only take an hour or so once the glass has been cut and prepared for you. Next, use three screws at the top of the Plexiglass to secure it in the window frame to prevent it from falling out.

This is a DIY sizing exercise that gives a good looking effect that can hardly be recognised as vent system.

Before we start, it should be noted that when you hear reference to casement window air conditioner, it’s the same thing as a push-out window. The advantage of using a window kit is to stop heat from outside the room from coming into the space to be cooled.Although most portable air conditioner units come with a traditional window kit, you can absolutely fabricate an insert to fit into a pop-out window allowing you to vent your Portable Air Conditioner effectively. Some portable air conditioner units come with a panel for non-casement windows that has an exhaust hole.
