I will soon be moving into a townhouse apartment w/o central air. The downstairs is mostly one large room, so I stick a unit in a window at one end or the other, and I'm good. Upstairs is a different story. The two bedroom doors are on opposite "ends" of the landing (a distance of maybe 7-8 feet), and do not face each other. This is to say that they are perpendicular to each other, so there will not be a direct flow of air from one to the other. To further complicate matters, the stairs to the first floor lie between them. One of the rooms will be occupied only half the time, but when it IS occupied, it will need cooling/dehumidification. I don't want to purchase an entire additional unit if I can avoid it, as money is pretty tight. Does this sound like a setup where a fan placed in the door of Room #1 would be sufficient to circulate the cooled air over to Room #2?

Thanks!
