I can recommend you to buy a Goplus Evaporative Portable Air Conditioner, it's about 100 dollars and works well. There are a lot of cheap A/Cs which you can buy, but you must be ready that they won't work as good as the more expensive ones. It's more important who will install it because it's a little bit hard to install it by yourself at home. I know a good company that will be able to install it and it also can make an
aircon steam cleaning for you if you need it.
