You can run the evaporator several degrees below freezing if your car is in a hot climate. The warm air across the fins will keep the evap from freezing. Surely, you've been in a car with extremely cold vents haven't you? It is my belief that foreign cars and maybe ford incorporate the outside temp as a switch/relay that adjusts the evaporator temp sensor to cut the compressor out at a lower, below freezing temperature in the evaporator.
