What does the Outside Coil do for the AC System?Your AC system has refrigerant moving through it from the inside components to the outside ones over and over again when it is on. Along the journey, the refrigerant will run through the two coils. The coil that is outside of your home assists with heat exchange. While the indoor coil will allow the refrigerant to evaporate and then absorb heat, the exterior coil is where the refrigerant condenses and releases heat. Essentially, the way that your air conditioner will cool down your home is not by making cold air, but by removing the heat. The warm air that is blowing over the evaporator coil will lose its heat to the refrigerant, which is in the coil, the coil then cools the air down that keeps moving over it and the refrigerant takes the absorbed heat outside.
Problems with Dirty CoilsAll of the heat that is absorbed has to go somewhere. If the coil has become dirty, then the heat is going to struggle to get out of the AC system. This can lead to a number of issues with the AC system, including:
- Higher energy costs: The air conditioner is going to keep running until the temperature inside the home is right. This results in higher energy bills for you.
- Insufficient cooling: The air is not going to be cool enough if the AC isn’t doing a good job of heat exchange.
- Indoor coils that become frozen: This issue often causes your inside evaporator coil to become frozen. Also, other parts of the AC unit may begin to breakdown because they are being overworked.
