Hard to know if the AC compressor is really turning on just because you select the AC internally- the car may actually only engage the compressor when you start moving off idle?

But the AC causing a 100-200 rpm increase in idle speed is common- as is a higher tendency to creep as the AT engagement is controlled by engine speed.
