Getting to Know Your Air Conditioning System: 3 Basic Components

It is important that homeowners contact a licensed, qualified professional for any Northern Virginia air conditioning services they may need. However, it is also a good idea to get to know the way in which your AC operates a little better. You should never attempt to service your system on your own, but having a basic understanding of the components that make up this system is a great way to ensure that you are able to recognize any problems with its performance. Here are a few components of your air conditioning system that you may not be familiar with, but which are absolutely necessary for its successful operation. Contact Polar Bear today with any questions you may still have.


The compressor is located in the outer unit of your air conditioning system, generally speaking. It is the compressor’s job to squeeze the refrigerant when it arrives in order to pack the molecules closer together, increasing its energy and temperature. From here the refrigerant makes its way to the condenser.


The condenser, also housed in the outside unit of your air conditioner, is the part that has metal fins. These fins allow heat to dissipate fairly quickly, which in turn allows the refrigerant to reach a much cooler temperature. When the refrigerant leaves the condenser it is no longer a gas but a high-pressure liquid. From here, through a very tiny opening, this liquid enters the evaporator.


The evaporator in your AC system is where the pressure of the refrigerant drops, turning it into a gas. Heat is extracted from the air surrounding it as it evaporates, and a fan is used to circulate the air in your home blows air across the evaporator fins.  When refrigerant leaves the evaporator it heads back to the compressor to repeat the whole process.
