Have you ever wondered how your central air in your Dallas, TX home works? Central air works in the same way as a refrigerator does. Instead of conditioning cool air in a small, insulated space like in the inside of a refrigerator, central cooling will cool a room, whole house or an entire business. Central air uses chemicals that are easily converted from a gas-state to a liquid-state and back again. This chemical is used to transfer heat from the warm air inside of a house to the outside air.

The central air unit has three main parts. These three main parts are the compressor, condenser and the evaporator. The compressor and condenser are typically located on the outside unit of the central cooling unit. The evaporator will be located on the inside of the home, sometimes as part of a furnace.  The fluid, known as Freon or refrigerant, arrives at the compressor as a cool, low-pressure gas. The compressor then squeezes the fluid. This compresses the molecules of the fluid closer together. The closer the molecules are in relation to each other, the higher the energy and temperature output.

The refrigerant leaves the compressor as a hot, high pressure gas and then it will flow into the condenser. If you have ever looked at the central cooling outside unit, you will have noticed a part that has metal fins all around it. These fins act just like a radiator in an automobile and helps dissipate heat more quickly. When the refrigerant leaves the condenser, its temperature is much cooler and it will have converted from a gaseous state to a liquid due to the high pressure. The liquid state will then flow into the evaporator through a very small, narrow hole. Once inside the evaporator the pressure will begin to drop.  Once again, the refrigerant will convert from a liquid state to a gas state.

As the liquid transforms, it extracts heat from the air around it. The heat in the surrounding air is needed in order for the molecules of the fluid to separate which is what assists in converting it from its liquid state to a gaseous state. The evaporator, like the condenser also has metal fins that assist in the exchange of thermal energy within the surrounding air. By the time the refrigerant leaves the evaporator, it has become a cooled, low-pressure gas. The process then repeats itself.

A fan is connected to the evaporator; this fan circulates the air within the home which is blown across the evaporator fins.  Warm air is lighter than cold air, so this heated air will rise to the top of a room quicker than cooled air will.  There will be a vent where air is distributed into the central cooling and will go through ducts. The warm air that is drawn in is used to help cool the gas that is within the evaporator.  As the warm air is removed from the area, cool air is brought in. This cool air is brought in through ducts that are usually located on the floor.

This process will continue over and over until the desired temperature is reached within the area. This is monitored by a thermostat that will sense when the temperature reaches the desired setting and then the central cooling will shut itself off until temperature levels reach a point where it needs to turn itself back on to bring the areas desired temperature levels back down.
