a.Too low refrigerant charge can for a while creates frost/ice on the suction line; however, after a while the frost/ice should go away when there is little or no refrigerant.
Refrigerant must flow to the evaporator coil for the system to work correctly. If the refrigerant is too low, it can cause the cooling coil to become too cold or freeze the suction line. Low refrigerant can also cause the air conditioner to stop cooling air altogether.
Frost Back: A condition in which liquid refrigerant may be flowing from the evaporator into the suction line. It's usually indicated by sweating or frosting of the suction line.
That's all from some quick Google searches...Somebody please set me straight here.
