Why is my AC coil frozen?
Frozen AC coils are caused by refrigerant leaks. Refrigerant is the chemical that runs through your AC coil, changing pressure and temperature in order to absorb heat. If it leaks, the lack of pressure will make it absorb more heat than it should. This makes the refrigerant lines, and then the coils, freeze over.
