How Does an Air Conditioner Work?

Air conditioning has been part of modern society ever since 1902 when a skilled engineer named Willis Haviland Carrier built the first air conditioner. [1] Ever since, air conditioners have been part of family homes to provide cooling and ventilation throughout. However, you might have wondered how exactly an AC unit blows hot and cold air. Whether you own a Goodman AC unit, a York air conditioner, or you’re about to purchase your very first AC unit, it doesn’t hurt to know the inner workings of your AC system. Our AC/HVAC team at All Brands Corp. is happy to discuss how an air conditioner works to give you a proper understanding of its mechanics.

The Process of Cooling Your Home

Central air systems include two connected coils where the refrigerant is continuously flowing inside them. The evaporator coil absorbs the heat in a room while the condenser coil is outside the room, usually hotter than its surroundings.

A compressor connects the condenser and the evaporator coils, increasing the pressure of the refrigerant so it can easily release its heat in the condenser before it returns to the evaporator. After releasing the heat it absorbed, however, the refridgerant still needs to cool a little more before it can continue. That’s where the expansion valve comes in. An expansion valve restricts the flow of the refrigerant in order to reduce the pressure and lower the temperature as is passes into the evaporator coil, where it will absorb more heat and continue the process.

The cool, low-pressured refrigerant flows from the evaporator into the compressor, churning out hot, high-pressured refrigerant to the condenser. A fan within the condenser pushes out the hot gas from the compressor as the gas gets condensed into a liquid and it cycles through the whole process again. This is how refrigerant functions in your home’s central AC system, oscillating between its gaseous and and liquid states throughout the heat absorption process, thus keeping the house cool.
