Do portable air conditioners require outside venting?
Yes, all portable air conditioners need to vent the hot air they remove from the room. These units commonly come with hoses to vent the exhaust and window filler kits to allow you to properly vent out of most windows. However, you do not need to vent the hot air out a window. The window venting kits also fit most sliding glass doors, or you may make a custom modification and vent the exhaust through a wall or into a drop ceiling. For these applications, you may have to extend the vent hose.
