Room Air Conditioners

Room or window air conditioners cool rooms rather than the entire home or business. Since they cool a smaller space, room air conditioners are less expensive to operate than central units, even though their efficiency is generally lower.Room air conditioner means any electrical appliance that has a compressor, a condenser, an evaporator and a fan to cool and dehumidify the surrounding air and that is capable in ordinary usage of being mounted in a window or through a wall.
