In reality, there are hundreds of parts that make up your air conditioning unit. Today, we'll focus on the most important parts of your air conditioner unit that will also be the most likely to need an AC repair.



Most people know by the name that the refrigerant in your AC unit cools. This fluid is an amazing piece of technology that takes heat from the interior and releases it outside. It is in constant motion as it undergoes a perpetual cycle of changing from a liquid to a vapor in order to accomplish this all important task. Every time you hear your air conditioning unit hum to life, this cycle is repeated. It's really cool to think about, isn't it?



The job of the compressor in this amazing heating and cooling process is to compress the refrigerant, thereby initiating the process of increasing its temperature. Once the temperature of the refrigerant is higher than the outdoor temperature, the heat will be able to be released outside.


Condenser Coil

These condenser coils are what you see in your outside AC unit. The heated refrigerant from the compressor flows here, releases its heat as the condenser fan blows air over it, and is then turned into a liquid phase again.


Expansion Valve

Next, our refrigerant meets the expansion valve where it is cooled down before it heads to the evaporator coils. The pressure of the refrigerant decreases, which is what cools it. This valve also controls how much new refrigerant comes and goes into the system.


Evaporator Coils

The evaporator on your air conditioning unit is where the hot air from your home goes to be cooled. These are connected to the expansion valve. The cooled refrigerant flows from the expansion valve to the evaporator coils. As your home's air meets the cold coils, the heat is absorbed from the air. Air is blown over the coils by the air handler fan. The heat will cause the liquid to turn into a gas, and this amazing process happens all over again.

This is a general overview of the process. Other small processes happen that work together to cool your home or office.
