Everytime I go to turn my AC on their will be a ringing noise. Kinda like a school bell. *** is that? HELP

That is the sound of either a bad blower motor (will do it in all modes, not just a/c) or a problem in the a/c system if only doing it in a/c.  Typically if isolated to the a/c setting it is a problem in the compressor and the dang thing has to be replaced.  A loose condensor or coil can cause this as well if the mounts are loose or busted.  Turn on the a/c and listen under the hood to locate it.  If at the compressor you gotta get a new one or bypass it with a shorter belt.

mine just recently started sounding like a grinder time to replace the blower motor.
