How Frozen Evaporator Coils Can Affect Airflow and Efficiency of Your HVAC System

Ac Coils Frozen

Did you know that frozen evaporator coils have a great effect on how your HVAC system works? Frost is known as the root cause of many HVAC problems, including restricted airflow and inefficiency. Continue reading to know how frozen evaporator coils create these issues in your HVAC system.

Signs That You Have a Frosted Evaporator Coil

  • If your evaporator coils are frozen, it means that something is wrong in your heating and cooling system. Ignoring this problem can cause your compressor to burn out. So, before the costly repair becomes necessary, make sure to know the signs of frozen evaporator coils as early as now.
  • Airflow is diminished when your unit is working a bit longer.
  • Your indoor space becomes less comfortable even if you set your thermostat at the right temperature.
  • Your unit works again even if you leave it off for certain hours for ice-melting.
  • Your energy bill dramatically increases.

If you experience these problems on your HVAC system, it is important that you address them right away. Take note that a frozen evaporator coil is never a good thing when you care that much about your comfort and money.

How Does Reduced Airflow Occur with Frozen Evaporator Coils?

When the temperature of your evaporator coil dropped below the dew point, the dew only builds up on your coil’s surface. This one cannot create a major issue on your HVAC system. But if the temperature of your evaporator coil drops below the freezing point and the accumulated dew turns into frost, your system will surely face a serious problem. Your unit will have a hard time keeping proper airflow inside your living space.

How Does Inefficiency Occur with Frozen Evaporator Coils?

The thin layers of ice forming on your evaporator coil’s surface can help boost the efficiency of your HVAC unit, as they help increase the surface area of your evaporator tubes. But as the layers become thicker and thicker, the efficiency level is reduced. The subsequent ice that make the layers thick will appear glassy, depending on the airflow, humidity, and temperature of your evaporator coil. These thick ice layers are known as radiant or hoar frost and they severely reduce your evaporator’s capacity to absorb more heat during the cold season.
