A/C pump kicking on and off after cold start?

Hey guys I am not quite sure if this is a problem but it is definitely strange to me since I have never had a car do this before. Anyways here is precisely what happens.

1. Start car in the morning (55 degrees ish outside)
2. While idling the A/C pump harshly kicks on and then off at least 4-5 times
3. My A/C is turned off and it was turned off before the car was shut off last. Also the defog is turned off too. (not sure if the A/C pump kicks on for that or not..)
4. I sit there confused..

I dont know if this is normal or not but I sure would like to know. I know this kind of behaviour from other cars I have owned when the A/C isnt charged and you try and turn it on and the pump just kicks on and off because it doesnt have enough pressure but this seems like a totally different situation..

Also my A/C does work and blow cold (although it could be colder..)

Any help would be great thanks guys!
