Noise at startup

I get a loud screaching noise when I start my car. It happens when the car is cold (first thing in the morning, or sat and cooled off).
It sound just about like screaching nails on a chaulkboard. Only happens for the first second or two. Anyone have any ideas what it is...or if it's killing my car?
Ohh it's a 2.3 SEL

Bartman1 is correct... It is liquid refridgerent being pushed out. The refridgerent migrates to the lowest and coolest spot in the system when off. Every Ford does it at some point. If you run the engine for a minute or two it will warm up the freon and help reduce this noise.
