Some air conditioner manufacturers claim to sell portable air conditioners that do not require venting. These units simply do not exist. All portable air conditioners need to vent the hot air they remove from the room they are cooling. It is important to note that the hot air does not need to be vented to the outside via a window. Another option is to use a room where high temperature is not an issue, like a storage room.

There are a few simple steps to take when venting your portable air conditioner. You should find a location for the vent first, whether it be window, wall or drop ceiling. Next, you should slide the exhaust connector over the discharge opening at the back of the portable air conditioner. Then, connect the exhaust hose to the exhaust connector. Connecting the venting window kit adaptor to the window kit is the next step. Finally, you should set the window venting kit into the window and shut the window.

The ideal length of an exhaust hose is 5-7 feet. It should be 5 inches in diameter. The length of the hose should not be extended. If you extend the hose and there is a backpressure or constriction to the airflow, the unit will not work and possibly be damaged as well. If it is absolutely necessary to extend the hose, you should make sure the diameter is increased along with the length. Be sure to note that the efficiency of the portable air conditioner will be decreased. You should read the warranty manual before making any alterations to the hose because some manufacturers do not allow it.If the dryer vent has external vents, you should not use that as a venting option. The compressor on your portable air conditioner is not strong enough to push the flaps open.
