Is There A Portable Air Conditioner That Doesn't Need Venting?
People often ask us if there is a portable air conditioner that doesn't need venting. The short answer is, "no". All portable air conditioners require some sort of venting to remove the hot air from a room.
However, you can pick up an evaporative cooler and these require not venting. But they don't work well in humidity. You can really only use an evaporative cooler in dry heat - like the desert.
