Interesting thing is that apparently these hydrocarbon based
refigerants are OK to replace R-134 but are not OK to replace
CFC-12 (Freon) in most states.  Therefore the procedure technically
requires conversion from CFC-12 to R-134 to Duracool/HC-12a/etc

See question #10 of this page:

http://www.epa.gov/ozone/snap/refrigerants/hc-12a.html

Unfortunately, it appears that Washington is on the list of states that
can't use HC based refrigerants at all (see above link, Question #10).

If you want to go from Freon to something else, here's the EPA approved
list:
