How Do Central Air Conditioners Work?

Central Air Conditioning System

Many homeowners know they need a heating and air conditioning system to keep their home comfortable year-round, but most don’t know exactly how their systems work. Today, we’re giving you a little peek inside how your central air conditioner operates.

What Is Central Air Conditioning?

In this context, “central” means you have one system piped throughout the whole house, and a single pump controlling the cooling process. This is different than wall-mounted or window air conditioners, whose temperature controls are unique to each unit.

How Does My Central Air Conditioner Cool the Air Inside My House?

When a liquid is converted into its gaseous form, this gas absorbs heat. Air conditioners use a chemical refrigerant (like Freon) that turns from liquid to gas at very low temperatures. It’s pumped through an evaporator coil, where the refrigerant absorbs the heat from your house, causing it to take on the form of gas.

This gas is cycled through the system by the compressor, increasing the temperature, and pushing it back to the outside. Then the gas is cooled back down to liquid form by the condenser, and the heat is vented from the system. Back in its liquid form, the refrigerant flows through the expansion valve and back into the evaporator coil, starting the process all over again.
