I mentioned Freeze 12 to my mechanic today and he had never heard of
it.  Granted, he is not an Air Conditioning specialist, but What
exactly is Freeze 12?  Is it an offshoot of Freon 12?

It was put into my unit last year in Texas and I am going to need a
new compressor so need to find out about it.
