Air Conditioning Upgrade

[Ed Kellock]

I just did the 1992 Firebird with a kit from Advance Auto.  It just had
fitting adaptors and 3 cans of 134a w/oil.  The system on the car had been
completely devoid of freon for several years so I just filled it up and it's
blowing cold.  Different animal though, the Pontiac versus an Audi.  I tried
to use the left over to charge the 93 V8, but the fitting wasn't correct.
My Avant needs AC service too.  This year it seems to have no cold-ability.
I might try to convert it as well.

Figured it would be a good time to ask about how difficult it would be to
refit my '91 Avant 20 Valve Turbo 
with a 134 system?

It seems to be getting more and more difficult to service the old Freon
system......or.....

Anyone know of an A/C shop in Denver with Freon?

Really no reason to spend that amount. If there is metal in teh system, it
will need a compressor and expansion valve, reciever dryer, and all the
o-rings. Other than that, it's all labor. Pull it apart, blow through
everything with interdynamics cleaner, and reassemble. Less than $600 in
parts, at my standard markup. I just don't see $4400. I really don't see
more than $1500 for this job, but maybe my rent is much lower than theirs
;-)
