AC FAQ: What Are the Coils?

If you use a whole-home air conditioning system, you probably are aware of the fact that you have both an indoor unit and an outdoor unit in the system. Chances are, though, that you don’t know much more than this. That’s okay. Most homeowners are perfectly happy so long as their ACs are blowing cool air.

We believe that it’s beneficial to have a basic understanding of your air conditioner in Everett, WA, even if you should never attempt to service it on your own. Read on to learn a bit more about the coils in your home cooling system. When you need any air conditioning services, be sure to dial our number. 

The Evaporator Coil

The indoor coil in your air conditioning system is called the evaporator coil. It is within this coil, appropriately enough, that refrigerant is evaporated. Why must this happen? Well, refrigerant is the heat transfer fluid in an air conditioning system, and it absorbs heat from the air surrounding the coil when it evaporates. It’s important to remember that your AC does not generate cool air, but rather removes heat from the air that is already in your home. The refrigerant, and the evaporator coil itself, play a vital role in this operation.

The Condenser Coil

Once the refrigerant in your air conditioning system has absorbed enough heat, that heat has to go somewhere. It cannot just be released in the house, obviously, or the whole process would be pointless. Instead, the refrigerant makes its way out to the condenser coil. There, it is condensed and cooled, and its heat is shed into the air outside. The process will continue over and over again, until the air in your home is cooled down to the desired temperature.
