You can convert literally anything from R-12, to 134-A. All it consists of is blowing out the old stuff, putting the adapter fittings on the inlets which attach to what's there already, and charging the system.

The question is, WHY would you unless you had no choice..?

134-A, Is more environmentally friendly but nowhere near as cold, if you compare the two of them. Most people wait 'til the very last possible minute to make the conversion. As long as I can ever still get R-12, I will keep my systems running on it. Until the supply of R-12 is totally gone, everywhere, I will use it until it's not available and I haveto switch over. Just my two cents...
