Room air conditioners are small-sized units that are completely self-contained and are intended for use in just a single room. Most frequently, you will see these small air conditioners mounted in window openings and occasionally they are seen installed through an opening in an exterior wall. They must have the back portion of the unit installed so that it has clear access to the out-of-doors for airflow, in order to work correctly.

For small spaces, a room air conditioner can be just the right type of cooling system to bring relief from the summer heat. The most common type of room air conditioners are rather small and are designed to be installed either into an external wall or into a window so that the unit has good ventilation and airflow. In recent years, portable air conditioning units have also been introduced, which feature a flexible hose for venting and casters for ease of movement to different rooms.
