Most likely it's the fuel pump. My '02 Tahoe makes the same noise and it gets worse during the summer heat. It's located inside the gas tank so replacing it can be tricky and/or expensive. Unless/until the pump breaks, you just have to put up with it.

If the compressor is running, the blower is blowing, and there's no cold air, you need freon. If the whining is from under the hood, the compressor may be damaged. That's what happens when running without freon.
