Don't know much about A/C's, but I'm pretty sure that the operating
temperature is not at 0 deg C. The coils aren't filled with water,
they're some type of liquid similar to freon. According to a website I
found, the freezing point of freon-12 is -158C. Maybe some other
fluids/lubricants would cause the A/C to seize before the coils would.
