A room air conditioner is a small cooling device which can be mounted in a window or through a wall for the expression and exchange of air. Recently, there has been an introduction of portable air conditioning units, which are contained in cases that sit on the floor near a window with a tube for expression. These portable units usually have casters mounted to the bottom of the case allowing them to move easily from one place to another as needed.

The purpose of the air conditioner in a room is to cool the air within a small confined area and is not intended to be used as air-conditioning system of "whole house". They are most often used in houses or apartments where people are reside, therefore, are not permanently installed and can be removed and taken to a new location if the residents move.

Typically, a room air conditioner will have a control panel mounted somewhere on the front or on top, to give the user easy access to controls. Generally, there are independent controls for setting the target temperature and to control the fan speed to circulate the conditioned air around the room.

Most people are not aware that air conditioning units do not cool "technical" quarter. It is more correct to say that the room air conditioners remove heat from the air and then the moves to another part where the unit has been placed.

A pressure refrigerant, R-22, crosses the air conditioner unit when turned. While the unit is on, the capacitor pulls the refrigerant gas in the air conditioning system and then pressurized, which raises the gas temperature. This heated, high pressure gas travels to the side of the condenser coils, which are located in the outdoor portion of the drive where fans distribute the heat it has collected.

The cooled gas then condenses into a liquid, which moves to the back room of room air conditioner with the evaporator coils. At this point, these coils can absorb heat that is in the room. The fan then moves air through the unit. The thermostat controls the cycle of this process to maintain the desired temperature in the room.

Some room air conditioners have mechanical controls such as knobs and buttons. The newer air conditioning units are controlled with electronic touch-pads that tend to provide more functions and can regulate how the units operate in, the set point temperature, a timer for automatic shutdown and power have on , and other conveniences, most of which are designed to make the unit as energy efficient as possible.

To help consumers choose the best unit of room air conditioner, small air conditioners are rated for their level of energy efficiency by EnergyStar.gov, a service of the U.S. Department energy. The degree of energy efficiency (EER) is the cooling capacity of the unit, in terms of BTUs divided by the watts of electricity used by the unit. To have a degree of star power, a unit must have an EER model that is similar to 10 percent higher.
