What Causes the Evaporator Coil to Freeze Up?
When an evaporator coil freezes up, it is usually because of a combination of factors. First, there may be insufficient air flow over the coils. This can be caused by a clogged filter or dirty blower wheel which restricts airflow through the unit and prevents adequate heat exchange between refrigerant and warm air passing over the coils.
Additionally, if there is not enough refrigerant in the system then this will also reduce heat transfer efficiency leading to frost buildup on the evaporator coil.
Low temperatures outside can also play a role as cooler temperatures cause less evaporation of water vapor inside your home resulting in increased relative humidity levels. And that could lead to condensation forming on the cold surface of your evaporator coil causing frosting and freezing.
Finally, low return ductwork temperature combined with high indoor humidity levels can accelerate ice formation on an already-cold evaporator coil due to thermal conductivity from moisture-laden warmer air passing through metal supply registers onto colder metal surfaces like those found on an iced-over evaporator coil.
