The big question “Is there any ventless air conditioner that does not require hose or need to be vented to the outside of the room?” Well, unfortunately there is not available for this specification! As well we know, almost air conditioners use compressor to cool down the room. And the working principle of compressor always requires the air circulation to extract and remove the heat. Therefore, there is always water condensation (one of byproducts of the cooling process). But if you are looking for a unit that can work with almost ventless design then portable air conditioning is one of the best answers! “Yes” it also must be vented in order to make sure the unit will keep working properly. But the venting procedure is much easier and more practical than the venting mechanism of central AC system or window units. That’s why we can call portable air conditioners are almost ventless.

Why all air conditioning must be vented?

Like mentioned before, all of them need to be vented because they always extract hot air when they are cooling the room. Furthermore, this mechanism will make the system be powerful to cool the room! Therefore you have to let the hot air of your unit to the outside. And if you choose to buy and use the almost ventless portable air conditioners, the venting kit usually will be included to the one package with the unit! We can choose ceiling, door, wall or window to vent them properly (depending the design of your room). If we choose the casement windows for the installation, we can use Plexiglas that can be cut as well as the size of the windows of the room. Plexiglas is also helpful to allow the light from the outside through your window and enters into the room.
