Air conditioning recharging, any options???
I just spoke to my father in law and he was telling me that there is a new refrigerent that can be used in place of the old R12 and you do not have to change anything out.
Do any of you know anything about this. Also if there are no options for R12 what all do I have to change out to upgrade?
Thanks,
VETJET

The neew stuff is R-134. You have to change the O ring seals and sometimes they change the evaporator canister. I'm keeping mine in r-12, I have a friend whose dad does home central air conditioning recharges. He has a ton of r-12, and will do mine. So I'm not changing. Maybe you could look into this

I might not have been very clear, he is saying that the refrigerant that he seen was not R134 it was something that you could put straight into the system with R12, but the difference was that this new product has larger molecules???

Re: Air conditioning recharging, any options??? (chevyman)
The first link is the one Im using. And Freezone you do not need to change anything at all. I live close to Phoenix and it does work good as R12. I have it in two diffrent cars and still working good after 2 years. You'll need a fitting converter to get it to fit the R12 fittings. Just mark it good so someone knows what is in there. http://www.freezonerb276.com/FreeZone.html http://www.alltemp.ca/r406a.htm http://www.autofrost.com http://www.freeze-12.com/ http://www.geocities.com/~jsphilly/hotshot.html

I thought that freeze 12 was from the 70's, not something new.

Re: Air conditioning recharging, any options??? (VETJET)
There are several refrigerants you can use and are EPA approved for automotive use. ( NOT MIX though )..... However..... R12 and R134A are pure, one component refrigerants. Almost if not all of the other refrigerants that will work in auto systems are what is called blended refrigerants. While they may cool fine, the problem is if (when) they leak, one of the components can leak making it impossible to top off the system because the ratio on the components is now incorrect. Also virtually all A/C shops will not or are not set-up to handle anything except R12 or R134a so if you use another refrigerant then you are on your own for service. You will also need to pull a vacuum to do the initial charge . I would go with R134a as it works fine and is cheap to get anywhere. I am using it in my 69 stock system without any problems.. :cool: :cool:

Does anyone have a ballpark figure on the $$ to convert to R-134?

All you need to do is drain the OIL from the compressor and replace the old oil with esther oil and install a new drier..Have the system evacuated (vacuum) and charged. If a shop wants more than $100 or tells you that you need to change other things, go somewhere else. Of course this is assuming that you have nothing wrong to start with. :crazy:

Ball Park figure to change to R-134 is about $40 Bucks for the Kit. The kit includes the hoses , fittings , can of oil , 2 cans of refrigerant . All you need to change it over . I just bought mine at Pep Boys . Have not installed it yet but HOPE it works OK .

Re: Air conditioning recharging, any options??? (Tom73)
I highly recommend changing the accumulator/drier when swapping refrigerant. The older type is not compatible with R134a, plus it is probably used up by now anyway. They're about $30. You can rent a vacuum pump for about $15/weekend. If you're in the Dallas area, you can use mine for free.
Be aware that a straight swap to R134a will give you vent temps about 10F higher than R12. On the early cars (pre-73), you can adjust the POA valve and drop the temps to lower than R12. Later cars can be fitted with a smart-VOV that also lowers temps to R12 level, or even lower.
My '71 cranks out 40-43F vent temps on a hot day with R134a.
