This is some fancy method that isnt' ready yet.

Another page says "A wall cooling system is a sleeve air conditioner.
This is much like a window air conditioner, but it is set in the wall.
This wall unit is only a few years old. "

I don't think a 250K house built in 2007 on a half-acre lot would have a
room AC through the wall, but the other method isn't ready.

Maybe a motel style wall unit?
