Many people buy an air conditioner that is too large for the space, thinking it will cool better. An oversized air conditioner is actually less effective than a correctly sized unit, and wastes energy at the same time. Air conditioners remove heat AND humidity from the air. If the unit is too large, it will cool the room quickly, but only remove a portion of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools. Running a smaller unit for a longer time will use less energy to completely condition a room than running a larger unit for a shorter time.
