Why Is My AC Unit Frozen?

How can a device designed to be used during the sweltering summer season start to freeze? There are actually many reasons why your HVAC system could be collecting ice, including drainage problems, a malfunctioning thermostat, blocked air filters, and more. Any of these can cause the refrigerant to fall below 32 degrees, resulting in frozen evaporator coils and other internal components.

While the causes are not always clear, it’s important to stop using your AC unit as soon as you notice any freezing or frost buildup. Continued use can put a strain on your system, causing damage to the unit’s compressor and evaporator coils.

How to Fix a Frozen AC Unit

First, you’ll need to let the AC thaw. Turn off the power and wait for up to 24 hours. Once thawing is complete, turn on the fan function only to circulate air through the system and dry it out.

Unless you take steps to identify and repair the underlying causes of the freezing, it won’t be long until your system freezes again. You can try a couple of simple fixes on your own:

  • Examine the filters and change or clean them if they are dirty. Dirty filters can restrict airflow and cause freezing.
  • Clean the coils and fins around the evaporator. Dirt buildup can restrict airflow.

Can’t fix the issue on your own? Freezing may be due to low coolant levels, refrigerant leaks, or damage to the system. The pros at Gold Star Services have the training, talent, and tools to diagnose and repair your air conditioner in record time and ensure your system doesn’t break down when you need it most.
