Yes, R-12 is still available. As long as it's available (and it isn't exorbitantly expensive) you should try to stick with it and not convert. Anything other than R-12 in systems that were designed and built to use it will not be as efficient, have as much capacity or be as safe. You should try to make your system as leak-tight as you possibly can so you don't harm the environment and you don't waste that expensive R-12.

I used R12a. Works great, better than R134 and. I conversation required.

|Jcslocum||Grab R12 off Craigslist. DO it at home and have cool air.|

|gmendoza||I've seen cars with this type of refrigerant. It definitely cools well but most AC gurus will not approve.|

Many of the refrigerants, if burnt, generate toxic gasses. R-12 becomes Phosgene gas, very deadly. In fact, R-12 is what is called a "precursor" an intermediate compound. German chemists created it in order to create Phosgene gas. Because of R-12's unique properties it was used as a refrigerant. It was called a Safety refrigerant. In fact it was safer that Ammonia which was in general use at the time. It is a VERY efficient refrigerant, there still is no refrigerant more efficient and still as safe. Too bad it is very damaging to the Ozone layer.

IMHO it is only important to avoid R-1234yf.
It releases hydrofluoric acid if it catches fire and you really don't want to inhale that

It is illegal to use Propane or Butane in a mobile A/C system. Too flammable, in fact it is explosive. Just about all "replacements" are blended refrigerants. While they may work well, none of them can duplicate the original for total cooling capacity. What that means is, you do not get as much cooling as you would if you stuck with the refrigerant the system was designed for. You will notice on a really hot day it just doesn't seem to cool enough. Bottom line, if you can still get the refrigerant your system was designed for, even if costs a bit more, it is not worth converting. R-12 is still available on E-Bay and you need less than 3 lbs. Fix your system so it doesn't leak. Use a leak sealer if you have to. To convert a system properly is a big deal. You should drain all of the oil, flush, refill with different oil, replace the dryer, and then charge with refrigerant. The service ports are supposed to be changed and the system must be labeled so you know it was converted and how much refrigerant to put in.

I'll stick with R12 thank you very much. The Esprit was designed for R12, R12 is available, the cost of R12 adds about $80 to your AC service bill. R12 does not explode, is legal if dispensed by a certified tech, and I run it in my Florida '89 and it performs very well.

Well is it a better charge?
Vendor claims so
Let’s see some numbers and or a back to back comparison
It’s flammable in a system not designed for such
What about oil circulation and compatibility
Without a proper charge oil won’t circulate properly
I know a Small bit about exige ac and significant enough improvements can be made there without radical changes

There is quite strong willed people on both sides of the argument for and against these types of refrigerants. I was not too interested and just skimmed over the threads on other forums.
I want to say these refrigerants are flammable and some consider them dangerous. What are you thoughts on the counter arguments?
I like the idea of getting way better AC with just a refrigerant change.

Appears to be LPG
not me, man
and they brag about not having mercaptan[which caused me to say, hmm, why would it have mercaptan]
yeah, not me

Recharging A/C, 134a replacement
I'm about to recharge my AC system with this miracle substance.
My brother, who lives in much warmer climate, swears by it.
Buy only "Industrial" cans. 6 oz of Enviro-Safe Industrial equals 16 oz of R134a!! Use less refrigerant, get lower high side pressure, colder temps and use less horsepower to get the colder air!
Also, ProSeal for Auto & Other Mobile Refrigerant Application Can #2060A works good. 4 ounce aerosol can contains enough sealant to repair small leaks and connects to regular mobile systems.
