Find another AC place.

Northern European Automotive ( converted my grey Avant to R134.
They vacuumed the system, replaced an external temp sensor in the plenum, and added the correct R134 friendly oil and of course R134....

No replacement of the receiver/dryer, etc.

This was done 6 months ago.  The CC blows air that is much colder than it ever has been in my indigo avant, even after that car had a refill of $$$ R12.
