After a weekend of driving through some of the hot parts of CA & NV (100 - 103F in places), AC system repair / upgrade has moved to the top of my 'to-do' list (that together with transmission overhaul, but that's a separate post...). The system was last working fine (well for a Westy that is) for two summers after a system charge in Spring 2007, but the freon has obviously leaked away since then. I'm considering conversion to Freeze-12 rather than another R12 recharge (since the R12 will undoubtably leak away again, adding to the ozone hole..). Advice from anyone who has done this conversion would be appreciated. I am ready to attempt this myself, but would consider a shop job if anyone knows of capable AC shops in the San Francisco Bay Area.

Thanks,
Mike ('87 Westy)
