Chirping sound

I have an '01 F-150 with a 4.6. It has just about 78,000 miles on it now. I purchased the truck last summer. Usually when I'm driving on the highway I have the radio up loud enough to were I do not hear the engine to much. But recently I drove with the radio off on the highway. When I was driving at around 70mph or so and at around 2000rpm i would hear a kinda chirping sound every now and then. It seemed to come when I would either accelerate a little harder or when I would take cruise and then accelerate.

Does anyone know what this is, and if it is any sort of problem?

Thanks for the Help.

my truck does it every once in a while. it just chirps for a quick second. its your a/c compressor kicking on. this might be what you are hearing.

If it's the a/c should it only chirp when I first turn it on? I have noticed it when the a/c isn't on.

the compressor for the a/c turns on and off while the a/c in the cab is blowing. if you actually have the a/c off then this is probably not the chirping sound that you are hearing.
