Some manufacturers put in a control that increases the throttle position to maintain engine RPMs when a load is applied (like your AC). If this isn't adjusted correctly, your engine RPMs will increase a little more than intended. That is what I think is the issue with your car and your AC is otherwise fine.

there's an idle up circuit for a/c and power steering. normal. at idle, these motors just don't have any power. so..... don't think the sol can jump you up to high. unless your idle is set to high in the first place.

Increasing engine idle is not bad for the a/c its just another thing for the engine to run and takes quite some power in running it so for the engine not to bog down it has to increase the idle everytime the compressor is on.
