1258 Air Return Outside Room - Air Conditioning - Duct System -

Image Text: When the air return is outside the bedroom (e.g., in the hallway) the door should be trimmed at the bottom to provide at least a 3/4 inch air circulation gap > if the air cannot circulate, the room becomes pressurized and will not cool down because it cannot accept any more cool air > trim here > supply register
