[Clyde Romero (clyderomerof4]

Thank you

Theses guys done understand that the system has to be made for a R134 system in order to work

In victory you deserve Champagne

In defeat you need it!

     

Scars are Tattoos with better stories !

If you follow all the rules

       I know a bit about this subject as I've self-trained myself and now do all my own AC recharging and repair.

       There are a bunch of "commercial" refrigerants that are used in home refrigerators, industrial AC units, etc.  R22, R408, R410 and a bunch more.
       The problem with using them in an auto A/C system is that an AC system is designed for use with a specific refrigerant.  Each refrigerant has properties like how much heat they'll "soak up", working pressures, oil requirements, etc.  Just dumping in any old refrigerant generally will not work well - wrong pressures, wrong size of condenser, wrong size expansion valve or TVX valve, etc.  The desiccant material in the drier must be compatible with the refrigerant as well.  This is why just putting R134a in a R12 system doesn't work as well - R134a needs different sized components to work properly.

       Some "replacement R-12" refrigerants do contain propane or butane.  Both work fine as a refrigerant, but are highly flammable if they leak.

       I've helped out a few people with R-12 systems and I always recommend staying with R-12.  The system was designed for that refrigerant and will work best with R-12.

       R-12 cans can be had on eBay, that's where I buy mine.  14oz cans runs around $25-35 or so.  Per eBay rules you either have to have an EPA 609 licence or must sign a statement declaring that you are buying the cans in order to transfer them to a licensed technician.  Most sellers will require one or the other.

       Does it take weeks of study and hundreds of dollars to get a EPA 609 cert?  Nope.  Go to http://www.epatest.com/609/ , pay your $19.95, read the study guide then take an open book exam.  So easy, even a Porsche driver can do it!
       Once you have a license you can legally buy your own R-12 and then find a tech to charge up or top off your system.
       Also, some auto parts stores can order R-12 for you if you show them your 609 cert.
