Every compressor-based portable AC needs somewhere to reject the heat it pulls out of the room, normally through an exhaust hose vented outside. Some models can vent through a wall port, a dryer vent, or a drop ceiling instead of a window, but none of the mainstream single-hose or dual-hose units can run with the exhaust hose fully sealed indoors. Evaporative coolers, which do not use a compressor, can run without any venting but only lower the temperature a few degrees and add humidity, which is not a true substitute in humid climates.

Most portable AC kits ship with an adjustable slider panel designed for standard double-hung windows and often include a second bracket for casement or sliding windows. For sliding glass doors, a dedicated slider door venting kit (sold separately for some brands) seals the hose through a vertical track instead of a horizontal one. Check the specific model's included kit before buying if your window type is anything other than a standard double-hung.
