Try looking around for something used/big you can mount in one window. I have a big one stuck in a window that I have to cycle on and off on all but the warmest (110+) days or else the room gets too cool, even on the low setting (250W). On high (500W) I'm pretty sure it could cool the entire house but I'd need a window on the opposite side since the exits would be in the rooms.

I would have thought it would increase the humidity, but, no change on my hydrometer. The inside of the apartment pretty much falls in line with whatever the humidity is right before I close the door/window in the morning, and doesn't rise, even if I use the evaporator. It's strange.
