Help with AC Compressor!

Howdy!
I just got my 06GT a few weeks ago......got ~1000miles on it already .......However, I have a question concerning AC Compressor....When I drive with my windows down and this being south TX, its HOT, however, I hear it cycling on and off like every minute or so, sounding like a air tank purge on a big rig or a wastegate (gee thanks ford! ). Is there anything wrong with it? My Honda did it when the AC system was overcharged and the clutch would not engage and my other Mustang did it when it was low on freon. BTW, the AC still blows icicles!!! And oh yeah, GREAT CAR
