Understanding the inner workings of your air conditioning unit is imperative for proper maintenance. By learning the importance of each component in the ecosystem, the function it serves, and signs of problems with each, you’ll be better positioned to recognize when it may be time for a repair or replacement. Annual checkups ensure each component is in proper working order.

5 Critical Components of Air Conditioning Systems

1. Refrigerant

Refrigerant sometimes referred to a “Freon,” is a chemical blend responsible for absorbing heat from the air in your home and releasing it outside. This process is what helps keep the air coming from your air conditioning cool. If your refrigerant lines aren’t properly installed and connected, it hinders the system’s ability to properly cycle and transfer the heat in the cooling process.

2. Compressor

If your air conditioning system was a human body, the compressor would be the heart. Located in the outside condenser unit of your AC, the purpose of this component is to add pressure and heat to the refrigerant. The main function is to “compress” the refrigerant to increase energy and temperature from a cool, low-pressure gas to hot, high-pressure gas. If the compressor fails, an air conditioning replacement may be necessary, as it affects the entire system.

3. Condenser

After the condenser, the next place the refrigerant goes is the condenser coils, which are responsible for ventilating and expelling the heat from the refrigerant and away from the air conditioning unit. A common problem people experience with condensers is the buildup of dirt, dust, and debris, which can prevent proper airflow.

4. Evaporator Coils

Evaporator coils are in inside your air conditioning unit and pull heat from the air in your home. Once the refrigerant has been turned into a cool liquid from the compressor and condenser, the evaporator coils extract and lower the air temperature. This is where most of the cooling occurs, so if your air conditioning system isn’t producing cool air as it should, it may be a sign of faulty evaporator coils.

5. Fan

As the air circulates through the condenser coils, the AC fan blows air to cool the coils, which then flows cool air through the ducts and vents in your home. The fan also plays a role in absorbing warm air from inside the home to provide heat to the refrigerant. If your air filters are clogged, you may experience inadequate levels of cool airflow.
