Anyone convert their A/C themself?
I was told I can have the system vacuumed for about $45 at an A/C shop, afterwhich I can buy a kit to recharge the system with the new R134 freon for about $30, myself. Anyone done this before?
thanks

Anyone convert their A/C themself?
Hi Jim, I Did a partial swap. The truck had an ac eliminator when I purchased it. Got a compressor from salvage yard($45) from a r134 truck. Changed the accumulator,orfice tube, high and low fittings(red and blue) and had a shop charge it. Shop advised pag oil for the conversion. You would have to drain the old oil,change accumulator, orfice tbe, high and low fittings and any oil seals that have been opened. I've heard of people just draining the compressor and changing the fittings, but that sounds like a quick fix to me. Counting the compressor, other parts and labor it cost me around $200 or so. If you're in question about charging it pay to have it done right the first time. Hope this helps. Later

why do you want to change it over, if it works I would stick with the r-12 untill you need to have some work done on it. The R-12 accually cools slightly better then the new r-134. I would not change it over unless you have to.

On my 1987 :
I did it myself...
Had a shop vaccum out everything.
Put oil/coolant.
Everything has worked great for 3 years.
I did not replace a single thing line or anything.
I live in Dallas, TX so it gets pretty hot down here.

1994 was the true year to CFC-free A/C(R134a). It is true that R12 cools better, so I wouldn't advise changing unless the system is dead. r12 can still be charged which is still cheaper than a complete conversion.
If the compressor isn't cycling, try replacing the high-psi switch at the accumulator. That's solved a problem for me several times.

I just changed the system over to the new in my '89 Taurus Wagon.....o.k., I paid to have it done.
$198 compared to $250 to charge with R-12.
Works good, even rolling past Death Valley @ 118*.
New 113= $18 a lb
R-12= $85 a lb
and it will only get more expensive.
I hear you can still go to Mexico and still get it dirt cheap.
