Freeze 12 Replacement for R-12

[bordin34]

I dont know how good a job he did. All i know is that it has the sticker and blows 50 degree air. If it has r-12 for some reason and I add 134a will it mess it up?

Blows 50 degree air you say, don't touch it. Unless thats the metric scale?

I might go ahead and convert my car over to 134 for cost but I am also considering keeping it old school, I still have a half full 30 lb. drum of the good stuff....... R12

IT WORKS.

Saw this on ebay -- is this stuff legit?    Is it really a simple replacement for R12 -- without going through the whole conversion?

If you take a look at the EPA site, you'll see that Freeze-12 is 80% R134a, which is safe, and 20% HCFC-142b, which is detrimental to the atmosphere, and will be phased out by 2010. So in essence, you're paying extra for a mix that will get more expensive as time goes on. Don't forget, it is 2007, so in 3 years when it's not produced anymore, the most cost effective switch will be to 100% R-134a, which is the accepted replacement in the HVAC industry for R-12. Those seals and o-rings are 35+ years old anyway.. spend a little more now, save later.

Im not sure if it blows 50 degree air. I know it was 60 degrees out and felt colder than outside so I figured 50. I will try to get a reading with my infrared temp gauage. It is not as cool as working A/C though.

R134A is also going to phased out, its worse for the ozone than r12

I would refer back to this website for further information.

  It's been a few years since I worked on A/C, however in Aussie R12 was banned and R134 was the replacement gas. It is not as good as R12, when I did a replacement I changed the compressor to a more efficent one and fitted a larger condensor ( the A/C rad. in front ) so that it would work close to the R12 systems.
  At the same time a gas that has been around many years, ER12 was used much to Duponts discussed ( they had no patent on it ) and went straight into the old system and worked great. When any system has been opened or been used for more than a couple of years it is best to replace the dryer and "o" rings, cheap insurance, I did it automatically then.
  Back to the ER12, the company manufacturing R134 did everything to discredit ER12 including making a film that showed a car being blown apart, of course when this was exposed as a fraud nobody could find the maker of this film. I'm not sure if it is still in use as I no longer work full time in the automotive trade.
  I have seen Liquid Petroleum Gas used but that could be dangerous and when I came across it I had to do a complete flush and oil & dryer change before regassing.
  R12 if used in a modern system would cool exceptionally well because of the different pump and larger condensor used, but alas it is banned.
  More could be said but I'm not stupid and cannot put it in writing, just see how many times in the coming years these gasses are changed and who benfits from that change!!

That is probably closer to the truth than anything, The makers of the refrigerants get to jerk our chains every few years for huge profits.

[buzzard]

Aussi I agree you can't say too much. Many of the magic refrigerants are based on propane [people propane burns]. Stick with r12 OR r134A . Think of the molicules of 12 vs 134  134 is like a BB and 12 like a basket ball, old A/C systems wont hold 134 replace hoses seals O-rings and oil. You can put a larger capacity condensor or electric fan in. Or live with the lower capacity.

  Those in the A/C industry at least in Aussie knew that there was nothing wrong with R12, but when a company spends at least a million dollars to have a gas discredited which they themselves had exclusive right to until the patent became tooo expensive to keep and others started to manufacture, questions should be asked??
  But suprise, suprise that company just happened to have another gas which again they had total patent on. You don't need to ponder for tooo long what it is all about.
