Portable AC Exhaust and Venting
All portable AC units have an insulated exhaust hose to vent hot air out of the room. The exhaust is usually vented outside through a window but can sometimes be vented to an attic or crawl space. When pricing portable air conditioners, be sure to include the cost of the exhaust hose and window adapter kit, if not included.
Portable AC units also need a way to dispose of the moisture removed from the air. There are several options:
- Self-Evaporating: These portable AC units release moisture in the form of water vapor that’s mixed with the heat exhaust, so there’s only one exhaust hose and no buckets to empty. Only use a self-evaporative unit if you’re venting to the outdoors, never vent moist air into an attic or crawl space.
