Mine does it too. I was listening to it last week as it was around 98 degrees at 10:30 in the morning...lovely day to pull 800 miles, but I digress.
It sounded to me like it was allowing the compressor to cycle occasionally while changing fan speed. The fan speed may be on a stepped resistor? It has to cycle from one specific speed to another, not linear. It never stopped blowing cold air.
