When you find that the indoor coil on an air conditioner is FROZEN and you have little to no subcooling, it is a clear indication of a refrigerant leak and a low refrigerant charge! This can be determined even while the coil is still frozen. If you do have subcooling, there could be another problem like low airflow or a liquid line restriction and you will need to melt the coil to further your diagnosis!
