Anything else i should do first?

[phil_long]

Ok guys, had my AC switched over to 134 some years ago.  I also had a new compresssor installed.  The AC only worked for about a week. NOW, the people I had charge my system put about 6 cans of freon in the car.  They claimed to have found NO leaks.  This was about 3-4 years ago.  Since then, I have installed a new resistor thingy for the blower for my digital dash.  I plan to take the car up to a professional place to have the AC system fixed.  Should I do anything else before I take it up there?

It takes less than four cans to fill a completely empty system so I think I would find a place that knew what they were doing.

Lol. Car was down in the country when that happened.  Diff times now.  Im taking it to a place that know what their doing.

anytime I have the system open I throw in a new orifice tube.
those seem to always collect alot of crap

Did the guys run a vacuum to get rid of any left over R12?

[phil_long]

I don't recall running any vacuum at all.  It wasn't working when got the car.  My dad thought it'd be best to switch it over.  I was young then and wasn't into the buick board like I am now.  No to the orifice tube as well.  What's the avg cost of getting the AC up and running(recharge system?)

It depends on the shop, honest, quality, thieves, lazy, short cuts.
i had the ac in my 01 GTP done, new condenser, orifice, and new something else, the system was flushed, vacuumed at -29.9 for a few hours and then recharged this thing was TOO cold. black car 5 people in it 95* and sunny outside i would have to have it on low or we would need sweaters. And the guy isn't an AC specialist. i think i paid $175.00 for the flush, vac and recharge.

the old AC stuff and new AC stuff are not compatible.
when i convert my GN.
1-New filters, orifice and that other "thing".
2-A good flush
3-Deep vac.
4-The same guy that did my GTP.
HMM AC or take the T-Tops off?? Both         

[phil_long]

Damn!!  That sounds like an awesome guy.  I know for a fact that nothing got flushed.  Idk what an orifice looks like OR where it goes, but I doubt tht got done as previously stated.  Wearing sweaters due to the AC sounds off the chain.  Lol
