When you go to a store or online retailer to browse different mini air conditioner models, you will have quite a bit of selection. The first, and most basic choice that you have will be which style you want: Split unit mini air conditioners have two separate parts (hence “split”): one that is mounted inside on your wall to pump out the air, and the other, on the outside of the house, that does the cooling. They are connected by a hose, usually that goes through a hole in the wall.
