R134 to R12

Anyone ever convert their a/c system from new to old, yes i know the gas is stupid expensive but those extra few degrees of cooling would absolutlely be worth it

Some have converted to R152a, as you may be aware.

@L31MaxExpress has claimed good results.

There is a difference between r12, and freon suitable for r12 systems. I'm not sure you can actually buy real r12 anymore. It used to require some formal training and a license to even purchase the real deal. I think most replacements are r417.

The automotive industry has yet again moved on. New stuff is R1234.

Yep, I had to go through that years ago. Now there's an R12 substitute. You want cold air, just throw propane in it! YMMV

Lmao, my old man showed me the propane trick with a bernzomatic torch bottle wjen I was just a kid. Yeah, I was licensed to buy r12 once upon a time.

I used some stuff called R-12A or R-12 synthetic brought my old system back too life

I still have this bad boy and it’s still heavy. Bought it in 1992.

That stuff is roughly 50/50% Propane/Isobutane mixture

R152a will do the same for alot less.

Now that the temps have dropped into the 90s my system blows 33-34°F before the compressor cycles. It was in the low 40s, upper 30s when it was 105°F outside.

Do you have a link to the process you did
