Freeze 12 question

HAve any of you guys used this , and if so, where did you get it? The queefers at O'Reilly's and A-Zone don't carry it because of the propane content -- Its a propane based R-12 substitute , --- my compressor works well, seemingly, but i dont have any cold air, and i am not emotionally prepared to do an R-134a conversion if its something that takes a while (which means i have a pretty stiff schedule this month and can't jack with a long, drawn out , conversion project )

If its not a big deal and i can do the conversion in a couple of hours, i can swing that though _ None of my old trucks have ever had AC except my new "beater truck", so its not something i've ever jacked with

Re: Freeze 12 question

I've seen lab work done up on freze12 and it is something like 98% R134A. Just part of the exadurated dramatization that DuPont started when they instantly lost a BUNCH of R12 buisness overnight.

Re: Freeze 12 question

i have used the 134-A direct into a vaced out working R-12 with no retro fit and no problems. also coverted a R-12 to red tec (r-12 replacement propane content) no problems and no retro fit just dumped in and a way it went (in a 1990 chev 1/2 ton). this has 6 year and still working just fine.did a red tec job on a leaking old R-12 with the stop leak and it lasted the season. the converson is olny as good as the A/C system was or is at the time you do the retrofit.

I didn't even let the R-12 out. I just bought a cheap dispenser that punches a hole in the side of the can and shot the 134 right in. Mine has a slow leak and I have to add a can or two every summer. I've been doing it for about 3 years. (nice and cold)!

Re: Freeze 12 question

I bought Freeze12 at my NAPA store. It worked as good as the system would let it.....I had a small leak that meant I had to add more every few months.

But it cooled my butt on hot days, so I say it's a go. No valves to change and entirely up to you to make it happen.

Re: Freeze 12 question

I used it on my car and it worked OK until (after a trip through the desert) it blew the seal that is in the compressor body (not the shaft seal).I did some research and you are SUPPOSED to add a high-side relief valve when converting to Freeze-12.
I bough out all 12 cans that Pep Boys had in the back.They don't stock it anymore.

Re: Freeze 12 question

the A/C is not as sensitive as people think... like I said, Du Pont lost a LOT of buisness overnight and created a panic. We dump 134A into R12 units on a regular basis at work.
There 4 outcomes here
Do nothing.... your a/c just doesn't work
put 134a in it, and it works great
put 134a and something goes wrong.... well, the A/C was dead before anyways
spend $1200 for aftermarket air.

Re: Freeze 12 question

Retrofitting consists of screwing on two new quick-connect ports over the existing R-12 ports. Then evacuate, and recharge and you are good to go. (Assuming everything worked prior to this) I think flushing the sytem prior to this will produce optimum results, but I have also converted without flushing, and it still worked very well.

Re: Freeze 12 question

the roumors of needing to charge more often are true however, the 134A gas does weap through the R12 hoses. I forgot to mention that.
I hope to get my front and rear A/C working this summer on the burb. It's pretty much all there and the compressor spins, so we'll be giving it a shot.
