Several common problems can cause air conditioner freeze-ups:


  • Insufficient Air Flow:

    • Anything that restricts air flow 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 can seriously impede air flow.

  • Outdoor Temperature:

    • Most 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.
