Summers in New Kingstown, PA, are warm and humid. You’ll surely turn to your air conditioning system for relief. While you expect the air conditioner to cool your home’s air, you don’t expect to see frost or even ice on the unit. Consider these four possible reasons why your AC unit is frozen.

1. Low Refrigerant

A refrigerant leak may cause your air conditioner to freeze up. If you see frost or icicles on the copper tubing, this is a likely cause of the problem. The frost and ice develop because the coil gets too cold, so moisture from the air condenses and freezes on it.

2. Malfunctioning Fan

The fan’s job is to blow warm, humid air from your house across the cold evaporator coil. This process warms the refrigerant and cools your home’s air. If the fan isn’t working right, the refrigerant stays cold, and the moisture freezes on the coil.

3. Dirty Air Filter

A dirty or clogged air filter also impedes airflow in your air conditioning system. When the warm air can’t pass over the cold coil, this creates a positive feedback loop. The coil just keeps getting colder, and the air in your residence stays warm. You’ll also notice ice buildup on the indoor unit and a possible puddle on the floor.

4. Faulty Thermostat

A thermostat malfunction may cause the AC unit to keep running. If it continues to run, the evaporator coil will get too cold. Air conditioner cycles should last for several minutes, then the system should turn off for a few minutes. This is a normal cycle. Constant cooling without cycling off should be cause for some concern.
