Does running the A/C without freon do damage to the compressor?

My wife was in an accident last month..not her fault. We got the car back from the repair shop and she noticed the A/C wasn't working. We took it back and found out that it had a big hole in the radiator shaped thing in the front. She had driven around for about two days with the a/c light on before we figured out there was not any freon in the system. I think the freon has oil in it to lubricate the compressor? Would running the a/c for two days do any damage? or should it be replaced?

There is a low pressure switch in the A/C system.
With no freon, the compressor clutch will not engage, therefore, the compressor, in your situation, should be just fine once the system is repaired and recharged.

i.e. the AC system won't actually run if the refrigerant charge gets too low.

Freon was a brand name of the old R-12, technically the R-134a used today is NOT Freon, but we all knew what you meant. Refrigerant is a good basic name that would apply to all the different fluid they put in AC systems.
