If you are refering to a window unit, they are very tough to size properly. Almost anything you get is going to cool the room in which you put it (maybe too much depending on size) but air distribution leaves a lot to be desired. Most people end up with a couple of smaller units for better temerature uniformity.

It kinda depends upon the space you are cooling/ type of unit you are buying/air distribution system/insulation in ceiling walls and floor/windows etc all have to be taken into consideration to properly size a unit, but other than that just get about a ton of AC for every 500 sg ft as a loose rule of thumb so a 1 1/2 ton should make you fairly cool. Note: 12,000 btus = 1 ton
