Anybody have freeze12 in their A/C system?

If you do, please post your opinion on them.
Was is it easy to retrofit the A/C to make it work?
(one person said he left it the same and it worked fine)

Any other choices?

For those of you in countries where it stays warm most of the time....you all better start thinking about an alternative to R12.
Checked out a local A/C guy, and he wanted $150 a pound for R12 (installing included of course).

I think most people buy a retro kit to change it over to R134a (i think thats it). It is probbably your best bet, and its not that expensive. R134a is super cheap compared to R12.

I from Central Valley of CA, summer temps stay in the range of 100 to 109. R134 isn't as good. The freeze 12 website gives lot of info http://www.freeze12.com/ . From the site:
FREEZE 12™ is EPA acceptable for mobile applications subject to the use conditions applicable to motor vehicle air conditioning.

FREEZE 12™ is an ideal replacement for R-12 requiring no extensive training.
FREEZE 12™ is a patented product.
FREEZE 12™ is non-flammable and contains no CFC'S.
FREEZE 12™ is made from readily available raw materials.
FREEZE 12™ requires no system flushes or lubricant change. It works with the existing R-12 lubricant.
FREEZE 12™ has been sold for several years and has been installed successfully in thousands of makes and models without problems. Conversion simply requires different fittings and labels which are available through H&H Co. (Click any store button)
FREEZE 12™ is the ideal replacement for older R-12 A/C systems that normally require expensive retrofitting to R-134a.
FREEZE 12™ is priced way below R-12.
FREEZE 12™ is lighter than R-12 therefore you will not have to use as much. Approximately 90% of the required R-12 charge is all that is needed.

Don't trust it. Too many claims for my taste.

I was in the auto industry for about 6 years and this is what I know about Freeze 12.

Good: It is *nearly* as effective as R-12 and *more* effective than R-134 in cooling your vehicle. It is considerably cheaper than R12. (although R-12 can still be purchased at some auto parts stores for about 24 bucks for a 12oz can)

Bad: Nearly ALL aftermarket and OEM air conditioning component manufacturers will NOT honor a warranty issue if Freeze-12 has been used in their component. I'm not sure of the reasoning, but IMHO, if I drop several hundred bucks on some AC hardware, then I'm not going to void all the warranties by dumping Freeze-12 into it.

I would also suggest buying the R-134 retrofit kit. It typically includes the high and low side adapters. The dispensing hose. The dispensing valve. 3 cans of R-134. and 1 8 oz can of oil. Some newer kits actually combine the freon and oil in one can. Typical price runs from 25-35 bucks and can be done by anyone (after you have the old R-12 evacuated, if it's not gone already).

Good luck and hope this helped a little,

p.s. additionally, if you do retrofit to R-134, it only takes 80% of the total amount of R-12 in order to fill your system. For example, if your car takes 28 oz of R-12, it would only need about 22.5 ounces of R-134. R-134 runs at a higher pressure.

Well....based on my research, this is what I've found out.
- compressor tends to break down (due to overworking to push R134 to blow at the correct temp)
- R134 is cheap, but compared to getting a new compressor, the leaking problem (Ian...you mentioned this in one of the posts - somebody else mentioned about smaller molecules of R134) and the cost/time of replacing the compressor, that offsets the cost of R134
- R12 locally will cost me almost $100 a pound (I know it's ridiculously expensive, but I don't have the license nor the equipment)

As for Freeze-12, so far only 2 people has replied concerning it. Both have positive reviews about it. One even has it in his system and supposedly he said that you don't have to change any o-rings...it doesn't leak.

If any of my research is wrong, please pitch in your experience.
I would rather go with R12 but I just had it checked and filled a year ago and the hose burst and it all escaped into the environment (I pretty much just killed the ozone layer) and can't afford to have that happen again.

Little more information from my own experience in this thread.

I am myself going through putting R12 in my car A/C system. In northern california if u do a search on craigslist for Freon, you will find 12 - 14 oz cans being sold in the price range of $20 - $35/ can. In Arizona it is costing me $50/ lbs of R12. I took my car to one of the local work shops here and they tested my system with Freeze 12 . When I asked him why isn't he using R12, he told me its the same thing. But after reading the above information, I guess he was wrong.

NissNX,
So do you have Freeze-12 in your system right now?
How does it work?
How long have you had it?
From your first sentence, it seems that you're not happy with Freeze-12 and you're going back to R12. Any reasons why?

I seriously doubt the valididty of anything they claim.
The EPA website gives no indication of any kind of product whatsoever that is a drop in replacement for R-12 in all situations.

Beyond the fact that some of the substances they list as being replacements are pretty hazardous themselves.

From a shop owners standpoint i wouldn't touch the stuff with a ten foot pole.

I did about 30 seconds of research on the EPA website and that is what i came up with. Most of the info is not government gibberish like you would think, but real down to earth terms.

I would highly recommend doing some more research before i buy any of that stuff.
