Portable Air Conditioners
A portable air conditioner rolls on casters and vents hot air through a hose to a window kit, so it cools a room where a window unit won't fit or isn't allowed — a casement or slider window, a rental, or a room you only need to cool now and then. A portable AC is easier to set up than a window unit but less efficient for the same BTU rating, and it takes up floor space. Dual-hose models generally cool faster than single-hose ones. Size it with some headroom for the room, and check the window kit, the noise level, and whether it also heats or dehumidifies.
