Air conditioning systems use a gas that is easily transferred into a liquid called R410A. This chemical transfers heat from the inside air to the outside.

The three main parts to an air conditioner are the compressor, condenser and an evaporator coil. The compressor and condenser are usually outside while the evaporator coil is usually inside.

When R410A meets the compressor, it is a cool, low-pressure gas. The compressor causes the gas to become hotter with higher energy by packing the molecules closer together. From there, the gas travels to the condenser as a hot, high pressure gas. The condensers job is to cool off the gas and turn it into a liquid. After it has cooled, it goes into a tiny hole which leads to the evaporator coil. The evaporator coil then causes the gas to evaporate into a liquid.While that happens, it removes the heat from the air around it. This heat separates the fluid molecules from a liquid to a gas. Once the fluid leaves the evaporator coil, it is a low pressure, cold gas. From there it returns to the compressor to begin the process over again.

A fan works along side the evaporator coil. The fan circulates the air through your home by pushing the cool air through your ducts. This process repeats till your thermostat detects that the air within your home has reached set temperature.
