lol, thanks for hitting both my AC related post.
If you see in the pic above, there is basically four rooms, and the open area in the basically the open area/stair way leading to the main floor. If I'm blowing the AC air from one end of the hallway to the other end, some of the AC air would probably sink to the lower floor right?
Lastly, if I needed just the south 2 rooms cooled, could I make something work with just one unit? Or would I still need both.
Unfortunately, portable is the only option right now
