What is a through-the-wall air conditioner?

A through-the-wall AC mounts in a permanent sleeve in an exterior wall instead of a window, so it seals tighter, stays secure and keeps the window free. Sizes run from about 8,000 to 14,000 BTU, often with heat. Replacement units must fit the existing sleeve size.
