Why Is Your AC Freezing Up

Specializing in service and repair of new and old Heating and Air Conditioning Systems

What Causes Air Conditioners to Freeze Up?

How is it possible for an air conditioner to look like an igloo, even in the warmest summer months? Needless to say, it is abnormal for ice to form on an air conditioner, and it is certainly cause for concern. Several common problems can cause air conditioner freeze-ups:

  • Insufficient Air Flow: Anything that restricts airflow will cause the temperature of the system’s evaporator coil to drop below freezing. Humidity in the air will collect on the coil causing ice to build up and diminish the system’s cooling capacity. Dirty air filters; collapsed, obstructed and undersized ducts; damaged blower motors; dirt build-up on the evaporator coil – all can seriously impede airflow.
  • Problems With The System’s Refrigeration. Refrigerant leaks or low levels of refrigerant can cause pressure drops in the air conditioner’s evaporator coil, which will allow moisture in the air to make your ac coil freeze up.
  • Outdoor Temperature: Most outdoor air conditioning units do not function well in temperatures below 60 degrees F. If night-time temperatures are too low, the system will not operate properly and freeze-ups can occur.
  • Turning The Thermostat To Low: Your ac is made to keep the home cool and dry most manufactures recommend not turning the temperature below 70 deg. If you are turning it lower then that it could be because of an underlying issue and you should call for ac repair and let your repair technician know so we are able to address.

What To Do When Your Air Conditioner Freezes Up

The buildup of ice and frost is a sure sign that your air conditioner is not operating properly. If you notice a decline in your system’s cooling capacity, ice build-up should be the first thing you suspect. Air conditioner freeze-ups should be addressed immediately; continued ice accumulation can cause permanent damage to your a/c unit.

The first thing you should do once you notice your air conditioner is frozen is to turn it off and let it defrost completely. Once it has defrosted, Clean or replace dirty filters or remove any visible dirt or obstructions; in some cases, this could be all that is needed.

More serious airflow and refrigeration problems require professional intervention. Schedule an AC Repair Appointment with The Heating And Air Conditioning Experts If problems Continue. Your Expert service technician has all the tools necessary to troubleshoot serious airflow problems and repair refrigerant leaks.

If your icing problem is due to drops in the outdoor air temperature, be sure to turn your air conditioner off when the outside temperatures drop. If you need to have the ac running in colder temperatures for gatherings, parties, events then let your technician know and we can install a special ambient temperature control that will allow the unit to run properly in cooler temperatures.
