Air Conditioning Unit Ice: Why Is It Happening?


Many people in Pensacola, Fort Walton Beach, and Panama City have found that there is ice on their air conditioning unit during the summer. It is so hot out and they don’t know why there is ice forming on their AC unit. This is much more common than you might think. There are two main reasons why this happens. The evaporator coil may have low airflow or the refrigerant levels may be low as well.

Evaporator Coil Low Airflow

You have an evaporator coil in your air conditioning unit. This is a very important part of your AC unit. The warm air will blow over your evaporator coil. The refrigerant will take away the heat out of the air. Then, the colder air will be sent back out throughout the home. However, if there isn’t enough warm air pushing against your evaporator coil, the refrigerant will become too cold. This can lead to the line on the refrigerant freezing up. There are various things that could cause this problem including the following:

  • A dirty or dusty evaporator coil
  • An air filter that is clogged
  • Blower fan issues
  • Leaky or collapsed air ducts
  • Blocked or closed air vents

If you call Peaden, we can check to see if any of these issues are happening.

Refrigerant Level Issues

Another reason why you may be getting ice on your air conditioning unit is when the refrigerant is low. When it is low, the temperature of the leftover refrigerant may drop down quite a bit, because of the lower pressure. This leads to the AC pipe freezing up. If you do have a low refrigerant level, it is likely due to a leak somewhere. You might see some problems besides the low refrigerant including the following:

  • Air leaking from the vents that is warmer
  • Higher energy bills
  • Hissing or bubbling noises from your refrigerant line
