Re: Here We Go Again!
That appears to be an advertising ploy. To my knowledge the automotive industry has not settled on a specific refrigerant as a replacement for R-134a. 134a was never intended to be the end product, just a stopgap measure until something better could be developed.Dick Whittington -
Re: Here We Go Again!
The other thing that I have found is, we know there was a huge buying frenzy of the R12....Well it seems that not that many cars are on the road that use it....So the price is way down. Last time I bought some (last year) it cost $10 a can (6 can lot on craigs list).
I just take the cars to a shop and supply him a can or two and I'm good to go for the summer.
So maybe stock up on the R134a for $10 per pound, hold it for 20 years, then sell it for say $10.50

Re: Here We Go Again!
Pete that is some good news about R12. I have not shopped Craig's list for it. Don't know what it sells for at the parts stores where you have to have a license to buy it. Driving my 85 today with temp in the 80's I think it may need a few ounces. ThanksComment

Re: Here We Go Again!
This has been comming for a while now, it's not new news. I recently got a newsletter from one of the refrigeration supply houses I deal with, it had an article referring to the futrue costs of HFC refrigerants which 134a is. One of the base chemicals has been and is still in increasing demand. Seems none of the manufacturers are uncreasing capacity to produce it, the article was a warning, the price is going the way of R12. That monster we created, China, seems to like the idea of refrigeration at home even air conditioning, that's what they blame it on. I'm sure this won't be the last change.Comment

Re: Here We Go Again!
Clem, I put refrigerants such as thank in the catagory of snake oil. A/C service stations, by law, must reclaim refrigerant any time they open the system. Most, such as we have done in the past, will reclaim it and either send it out for purification, or have the equipment to do it in the house. Odd ball snake oils will contaminate their systems and render the product they have reclaimed and stored in their equipment useless. Every wonder why reputable A/C service stations invested $1k or so in equipment to test the product in your system before they attempt to service it?Dick WhittingtonComment

Re: Here We Go Again!
Weren't we making progress WAY BACK WHEN on adopting helium as a UN certified refrigerant? I never heard why that technolgy alternative was abandoned...Comment

Re: Here We Go Again!
Jack, there have been many gases tested as a refrigerant. Unfortunately some of the best prospects are slightly flammable or outright flammable. Carbon monoxide is one that has been tested, and is actually in use in some off road equipment A/C systems.Dick WhittingtonComment

Re: Here We Go Again!
We ought to go back to the beginning and use ammonia.
An absorption system using lithium bromide would make use of exhaust heat as "free-o" energy to drive the process, but the equipment is far too cumbersome to work, without significant development.Comment
