I don't feel that your comparison to a house AC is valid.  Electrical
power is used to turn the compressor in that type of unit, while in a
car the compressor is turned by a belt from the engine.  The electrical
power needed to turn the fan and operate the clutch should be
considerably less than that.  I don't have any actual numbers, but 40 or
50 amps seemed like a lot.  Maybe the bearings in the fan are in need of
lubrication, thus causing it to use more than the expected current.
  Of course it's not much fun pulling the evaporator down to find out.

Good luck,
