Sleeve air conditioners solve a very specific spatial problem: you need serious cooling power in a room that cannot accommodate a window unit, and a central system is either too expensive or structurally impractical. These units mount through a dedicated wall sleeve, pushing the compressor and condenser outdoors while keeping the operating interface inside. The…
