That's what you'd expect from a working compressor. I wouldn't worry too much about the engine speed. Your diesel will have plenty of spare torque to engage the compressor on a cold January day when it doesn't have to work very hard at all. The next time your windows steam up in the rain, switch on the air conditioning. If it clears the mist after a few minutes you've nothing to be concerned about.
