We got a Halcyon Fujitsu mini-split room air conditioner wall mounted type/heat and cool. Our room faces West with a whole wall of windows. It would get over 100 degrees in the summer. I found the company on the internet and started looking for a local dealer. It mounts on the interior wall and a 3" hole is drilled for the air-conditioner that stays outside on the ground. It is the best thing we could of done for that hot room. Look it up on the internet. It is pricey, but the cool room is worth the cost.
