aside from the fact that this is a 14 year old thread...

icing is a symptom that CAN be caused by low refrigerant.

if a system is low on refrigerant, the compressor can create a lower than usual pressure in the evaporator. This causes PART of the evaporator to get colder than normal which can cause ice.

The overall capacity of the system is reduced because the rest of the evaporator is warmer than normal. Think of it this way, the compressor is still working but on a smaller load so it gets that smaller load colder then normal.

There are other issues that can cause ice but low charge is one of them especially if only part of the coil is iced.
