Why does an air conditioner have to be put in a window?

They expel warm air and water as byproducts of the cooling process, and there is no way to redirect these things if you attempt to run the unit anywhere other than a window.

Why is air conditioner placed in a window and not on the floor?

Since cold air is emitted from the A/C unit blowers, the unit has to be placed at the top of a room to allow a convection current to form. If the unit were to be placed near the floor, the cool air would be “stuck” at the bottom and the room would not be cooled effectively.

Why do air conditioners need outside air?

The outside portion of your air conditioner is most often referred to as the “condenser unit.” Whereas the inside part of your air conditioner is responsible for absorbing heat from your home’s air, your outside unit’s job is to release that heat to the air outside.

Why are air conditioners installed near the ceiling of rooms?
