I have an air conditioning unit hooked into a door on full blast, but it is still hot in the room I am in. I also have a floor fan (~3 ft diameter). I am wondering if it is better to have the fan on (back against the wall) blowing the cold air coming from the AC farther into the room, sitting inside another doorway (blowing the hot air out of the room) or turned off.
