engine moan with a/c

[bigmd]

ok guys,when i put the a/c on the engine gets much louder.does this happen to anyone?

Yip.

But how much louder? The engine is working harder + one or both of the fans are now engaged.

It also gives it more gas to make up for the torque the A/C uses. If it didnt idle up, then the rpms would drop.

There is also a Whhhhooooooooooooo sound.
It doesn't do that much when you use recirculate.
