Hi; I checked my sight glass on my A/C the other day when it got to 106 degrees, only to see lots and lots of bubbles go by. I can't find a store that has R-12 to sell or even install themselves. I don't want to convert to R-134a due to the fact that, while it is slightly better for the environment, it is nearly 3 times more likely to leak out and is several times more toxic, plus, R-134a is a carcinogin and R-12 isn't. If anyone out there has a bottle of R-12, I'd be willing to buy it from you. Thanks.

First off, you have to be licensed to buy R12, legally. Next, R134 doesn't leak out as easily as you say. I've swapped 3 MoPars over to R134. An 89 Voyager turbo, an 87 Diplomat and finally a 65 Cuda. Longest one running has been almost a year and a half without any leakage runing original hoses and compressor. The others I just did this year after I assured myself the R134 swap would work.

If I may make a suggestion.. I had my a/c system off and under the bench for two years. I decided to put it back on -and then was " led down ythe garden path" by every a/c guru in this area. To make a long story short I bought a case of " dura-cool " the stuff is a miracle!! I did not evacuate-vacuum- or any thing else!! Bolted it togather put in 40% of the R12 requirements and it works better than ever. It is advertised in MCG its about $70 a case.. Hope this helps !!

Your local dealer should have it. Afterall, it was factory installed. I know the dealerships here in Minnesota have it. It is very spendy per pound compared to R134a. I believe they are getting $30-35 per pound. I still have 2 or 3 single pound can's laying out in the garage. As someone stated in an earlier post, it is illegal to sell to non licensed installers.

Just used a similar product called RED TEK,
does not have oil pre-installed like the DURA-COOL(so Iv'e been told). Drop in replacement for R-12 $ 134A. Works very well and price was about $45 cdn for enough to do a car.

I know about this much about A/C: ZERO. But the r12 system in a ford full size I used to beat around town with needed a recharging but i was poe and didnt want to spend the $$ on the POS. Anyways, I picked up a r12 to 139a at K-mart for $39.99. It came with 3 cans of freon, oil, and the fittings to fill it. I drained the little r12 that was left with a car key (ya i know i just killed a tree or something), took a 50/50 guess as to which side was the "low side" and "high side" and dumped the stuff in. And it worked! I used it all summer and it kept me cool untill i got rid of the car.

There are several drop in replacements for R-12 - ie - they are compatable and require no updates or changes to an existing R-12 system. R134 produces a higher head pressure in the system and some compressors can not be reliably converted to R134. Also R134 is NOT as efficient as R12 and does not cool as efficiently. If you want to legally switch to R134 - you have to replace your R12 hoses with those certified for R134 - else most AC shops will not work on your system.

It is easy to acquire the federal certification required to purchase R12 or its substitutes. It costs $20 and the ability to take a mail in test!!!!!!

For all you want to know about this and certification visit these web sites....

You can retain your R12 system without spending a large amout of money.

I have one of those Auto Air Conditioning Kits with 2 cans of R12,instructions,indicator,fittings and hose. I bought it in the late 80's and it is still in the original packaging. What do you think?

Just to let ya know at our shop R-12 cost $56.00 a pound! So when most people come in with old systems they find out its cheaper just to convert since you can get r-134 for $5 a pound!

I just want to help out. How's 30 bucks total,incl shipping? There are 2 cans in the kit at 14oz. each can. Hey, I just read the other posts. I guess I'm in the dark. What's with the legallity thing. I don't want to commit some federal crime or anything like that. Is it legal for me to sell this kit and mail it? Can someone enlighten me please? If it's illegal, then what do I do with it since I don't need it?

Cool

Autofrost - a R12 drop in replacement is available for $9 per pound at this site:
http://www.recoverall.com/atcpage.html

The company is located in Indianna - there are other mfgs of drop in R12 refrigerant that are way lower than $56 a pound.

That means that AC shops can fix your R12 system without stiffing you - if they want to do so.

There are replacements for R12 without being stiffed by the R134 replacement syndrome. The AC industry would have you believe the only cheap alternative when your R12 system needs help is to convert to R134. This is simply not true.

Check out the other web sites in one of the following posts.

Hey Dart 340 swinger, what's the name of your shop so I can stay away from it. You pay $22 a pound for R12 and charge your customer's $56/lb. BOHICA.

I bought the R-134A conversion kit at discount auto parts. Then I saw the kit being used to convert a streed rod on Crank and Chrome (Shadetree Mechanic). Not too expensive or difficult to install. The web site has an FAQ that explains all.

i just recently did a conversion on a 74 chrysler boat with 440 and had an outlet temp of 52 degrees and that is in south texas. so if you want to convert and your system is in good mechanical condition your system should work just fine. i dont change hoses because the molecular structure of 134a is not that much smaller than 12 and wont leak out as fast as you would think. even if you had a small leak you could even out the cost in 4 years worth of charging to make up for hose cost. i have converted lots of cars and never had a single person tell me it is not as cold. nor have i had someone in telling me they are out of refrigerant......some of these conversions are over 5 years old including mine on my 87 4x4 dodge ram truck. good luck

Replying to the 134 R12 debate. I work for a caterpillar tractor dealer.We have converted several strip mine machines to 134 from r12.We changed the system oil to the universal oil,checked for vaccum leaks and charged as usiual with 134a.No problems after 3 summers.Anyone who works on ac knows this whole changeover thing is a hidden goverment tax. Keep cool wvmopar
