Subject: RE: BS: Portable air conditioners with no-drip
"# The room that I want to use the portable air conditioner in has windows that do NOT open, does the unit need to be vented?

Both hoses need to be connected in order for the unit to work to its fullest capability. If you do not connect the intake hose the machine will use the room air that has been cooled by the unit to cool the compressor therefore decreasing the amount of air conditioned air in the room. This, in turn, will cause the compressor to work harder in an effort to replace that cool air. If you do not connect the exhaust hose, the machine will be exhausting the air that is used to cool the compressor into your room. This air is warm and will therefore counteract the effects of the air conditioner. This will also cause the compressor to work harder and shorten the life of the unit.
