What happens if my AC runs out of freon?
When your AC unit is low on freon, the evaporator coil gets too cold and causes the cold liquid refrigerant to flow back the refrigerant line. This will cause the surrounding moisture on the refrigerant line to freeze up. This is a sign you need freon. You may even end up having to replace the entire AC unit.
