It was one of those jiffy lube type places. I didn't think it was going to be that complicated.

They charged:

A/C service: $39.99
1.7 of 134a: 67.00
Stop Leak: 39.99

for about $147 total

I know - I was hosed, but I thought they still used R12 & I couldn't even buy it.

Nope, R12 is not used anymore. Some mechanics may still have some laying around, but that is getting fewer and fewer.

Does anybody know how much total R12 these hold?

If I still had 1.5 lbs of R12 in there wouldn't that be plenty to cool, as long as the system hardware was working?

I have found that if you are low on refrigerant, the system tends to freeze up. It will work for a bit and then you have to turn it off for a few and wait for it to thaw out. I know that everyone can't do their own work, but that Jiffy Lube was really over charging. A can of 134 around here is $7 figure on 2 cans and good stop leak is $20 (best to replace the leaking part) So they really jacked you on the 143a.

I just replaced the compressor on my car, bought a venture vacuum pump at Harbor Freight for $14, 2 cans of 134a and a can of 134a with PAG oil. I had the hose with pressure guage. Cost me around $35 and it was easy to do. Blows 40 degree air. Of course my car uses 134a so no conversion was necessary .

I had a '91 T-bird that I had to do a conversion on, I flushed it out with compressed air as best as I could then added the new conversion fitting and vacuumed it down, added a can of oil/134a and charged it. It worked ok for the most part, but it was never as good as it was on R12 and not as good as a real R134a system.

Static, are those 16oz cans? It looks like the total capacity of R12 is 2.25 lbs, so for me that 1.7 lbs of 134a plus the stop-leak should be enough. I'm going to get it back up there & have their real mechanic check it out along with the pressure.

Thanks for the info. Hopefully that was my case & it really did just need more refrigerant.

&, when they quoted that price to me before it went in, I figured that was for R12. Seemed OK for that.
