Why does my car idle really high whenever the A/C is not on?

What is your question?

Whenever i turn off the Air Conditioning in my car, it will start to idle higher and higher, going all the way up to 3 and sometimes even 4 thousand RPMs, but it goes back down to normal when i turn the A/C or heat on, and there's nothing wrong with the way it drives, only when it is idling.
