Through-the-Wall Air Conditioners
A through the wall air conditioner installs in a sleeve built into an exterior wall, so it cools a room without blocking a window and stays in place year-round. Many purchases replace an existing wall AC unit, which makes the sleeve size the first thing to check: the new unit has to fit the sleeve you have, or the sleeve has to be replaced along with it. Some models also heat, with electric heat or a heat pump. Compare the BTU rating for the room size, the voltage (many need a 230-volt outlet), the sleeve dimensions, and whether the chassis also works in a window.
