The compressor in my Jetta is shot; and I would like to know if anyone has an idea of a good shop for A/C work? Or if anyone has the tools/experience to do the freon work. Swaping the compressor isn't that hard, but I've never done A/C work before.

Was the refrigerant already converted to 135a? if your system was not left open for a long time and it didn't get to contaminated, you can buy a filter dryer when you change it out the compressor and they sell a kit that gives you the gauge an a couple of bottles of 134a to charge it back up.
I've had luck doing this.

If an A/C compressor is seized then before it seized it will send debris through the entire system(Evaporator,Condensor,Reciver/dryer & H block(or sometimes called an Expantion valve) & these components can't be cleaned out. All the A/C lines can be cleaned out with Brake Clean & compressed air. If the system is not cleaned out compleatly then there is a good chance the Expantion valve will get plugged. Trust me. I have seen this many time. Another BIG thing is after you put everything back together you MUST pull a vacume on the system (30in) for atleast 30min to boil out all the moisture. This is very important so the system will work properly. Also NEVER reuse any seal or O ring on any conection because it will most likely leak later on down the road.
All cars & trucks by Federal law started using R134A in 1994. R12 is very hard to find & VERY Expensive.
Repairing A/C is usually not cheep even for me because the parts are expensive but the BIG cost is labor because replacing an Evap involves removing the entire dash on many cars. I have no experince doing A/C repair on VW's & wan't to keep it that way because every time I get stuck working on a VW it always turns into a nightmare. There's always some sort of special tool needed to do a repair on thoes Germin cars. No wonder they lost the WOR!!! I can definetly say replacing Evaps on "most" Honda's & Toyota's involves just removing the glove box & 2 of 3 halves of the heater box asembly. I gota say thoes Jap's got some good ideas sometimes but then again they also lost the WOR. Goes to show ya not to mess with the Good Ol USA.

Not even shure you can get R12 anymore but not shure how much you could sell that stuff for becauce it's not that expansive to get a retro kit for R12 to R134A & R134A is cheep. I have 3 12LB cans & not quite shure what to do with it. Gess ill just hang on to it cuzz I might need it some day. Ya never no. I always felt R12 worked better than R134A.

When the AC clutch siezed on the Liberty I did the job myself. I had the R143 reclaimed and then swapped out the compressor (can't swap just the clutch with the Liberty). I had to by the air dryer and the evap line to get the warranty through Advance Auto. After the repairs I had the system recharged. When I called the dealer it was estimated at $1200 and a 1 year warranty. I did the project for a little over $400 and I still got the 1 year warranty.
