Why do air conditioners need outside air?

To do that, air conditioning units use a cooling agent called refrigerant that absorbs the heat from the air, using a fan to redistribute that cool air. With no outside ventilation, you’ll end up feeding your unit recycled hot air. That’s why you need to use a hose to vent that warm air from a portable AC unit outside.

Do all air conditioners need to be vented outside?

The short answer is yes. Much like any air conditioning system, all portable air conditioners need to be vented in some form or fashion.
