A window air conditioner sits in an open window or a wall sleeve and cools one room. It is a common choice for apartments and bedrooms, and installation uses a bracket and side panels. The main points are the BTU figure, the room size the maker states, the window opening, the noise figure and the controls.
The six units below run from a 5,000 BTU mechanical model to a 12,000 BTU unit with a remote. Every figure comes from each product’s listing page and is the maker’s own, and some pages disagree with themselves, which we note. We have not used these air conditioners ourselves, and we make no promise about cooling results or running costs.
