One needs no licence to purchase and use R34 refigerant. It's available in
most any auto parts store and Wal Mart and K Mart.

It's actually called R134a, the refrigerant used in most automotive
air conditioners. You still need a gauge set, fittings, can tap,
vacuum pump, leak detector and a modicum of knowledge to do the job
properly.

I saw something interesting on one site. Apparently after all the
folderol about changing from R12 to R134a has died down the Europeans
are now considering mandating a change to (possibly) Carbon Dioxide.
Another possible is R152a.
