Been using negative/positive air pressure effect with the AC in the media room. One adjacent window open in a room with no other doors or window open. At night time, it gets scary cold.

I'm getting cold air from the AC and cold air rushing in from outside via open window. Firefighters use this to get rid of smoke trapped in rooms. Fan at one window is all it takes.

It's like recirc in a car, I guess. All I know is it works like a damn in my situation. I guess size of room/size of AC/size of window combo is just right.

Dirty look from MG1 can melt steel beams.
