Autofrost - new 134a compatible refrigerant

ScotY on Fri June 20, 2008 4:28 AM User is offlineView users profile

Is Autofrost 134a substitute refrigerant worth trying? They claim 10 degree lower vent temperatures and, of course, no negatives to using their product. More info is available here:

Why use a "blended" refrigerant when R134a andR12 are available.? If it's an older car, autofrost also recommends changing all the hoses due to leaks out of the hose, in my opinion, there are two refrigerants for automotive use. R12 and R134a.

Checked the web site for info...of course...it is not completely available.....company secrets and so forth....but...man is this stuff expensive.....if the advertisement on the web site is correct......wow!!! Also like any other blend, it must be charged as a liquid....must be recovered (special equipment) and supposedly can only be used once.....so...why...?????
Any major change in evap cooling (lower pressures) may result in an increase of system cycling...or in a variable compressor...simply result in a possible premature destroke event. Perhaps..some initial off idle cooling...but most 134a system will cool very well during most operational conditions. If a system is not 'up to par'...no amount of 'special' refrigerants/additives are going to make a major difference.
So, like Chick.....stay with the proven ones.....R12 or 134a....they work....work well....and do not contaminate anyones recovery system. Best for all involved.

Doesn't the use of any blended refrigerant void any and all warranties on compressors and other equipment used in the a/c system, or are there blends that are "approved" (not that I would use them anyway).

Use any refrigerant other than R12 or R134a and you void the warranty.

Yes, to the voiding of the warranty issue.....and yes to the 'approved' list...but this approval is from the EPA...meet standards...not performance or the effect on the system and system components.

Not to argue with you pal. But not one alternative was ever approved. These refrigerants were only accepted under the SNAP guidelines. To me there is a big difference between being approved and accepted.

I stand corrected.....the fact that the EPA accepted was a 'defacto' approval for the refrigerant production. The fact remains that this was for production/usage/recover and had nothing to do with test by various mfg'ers concerning the validity of the refrigerant as usage in compressor installations or service.
I placed a call concerning the compressor issue that you and I discussed....the 'tech' I need to talk to will be back in his office on Monday...AM....should have the info at that time.

Exactly, that's why I bring up the point it was accepted not approved under the SNAP program.

Cool, thanks!

This crap will not move oil the right way. Also blends are not a good idea. Part of the blend will leak out and then you don't know what you have. Why do you want to use alternative? Why not just retrofit to 134? Is it because 134 does not get your car cool enough?
