You AC system needs recharging, You will eventually find the engine starts doing this more frequently and also at a higher top rev. I have seen this twice on UK Mondeo's recharging the AC sorted this out, Also it didn't need AC selected for the problem to show it was there all of the time, but not too noticable when driving.
