10000 ft . Older louvred style. 2010 model year I believe. Works fine. Needs TLC but puts out the cold air. No remote. But easy to set and keep temp steady. Shuts off when reaching desired temp. On when room becomes hot again. Two hose ducts rather than new style of one. Needs window slat opening. Can buy on Burnside and remote. Drawback. I would not say this is energy efficient but we had the room (s) colder. Also heavy but has casters. Twin paired water tanks at back. As these models do not evaporate the water collected from air. 40 bucks take it away.
