2001 Chevy Blazer blowing cold then hot

I have a 2001 Chevy Blazer.  The AC will initially blow cold and then gets hot.  It takes about 15-20 minutes to go from cold to hot.  The odd part is that if I turn off the engine for about 10-12 hours, the AC will blow cold again for 15-20 min.  This is a repetitive cycle.  My local shop suggested I replace the entire unit at a cost of $1200.  Needless to say I don't want to do that.  Any suggestions are greatly appreciated.

Can't really answer but my '02 GMC did the same thing. 3 compresors later it acts like it's low on freeon and then quits. I think they are both GM problems they don't want to back up. To replace the compressor with a different brand is what the parts store told me. He had the same problem with an '03.
