1G R12 vs R134a advice needed!

[CrackedDSM]

Hey guys, short and sweet, I’m gonna get my A/C working soon as possible, and now I’m at the point where I need to decide if I wanna find some R12 to put in it or go wirh R134a.


So I need feedback from you guys in southern hell hole states or any state that gets 100-108*+. Do you use R12 or R134a? Do you have any issues with the temp of the air coming out of the vents on hot days? Any regrets? Tell me everything.

I ask because I’m hearing r134a conversions suck in tropical climates.

I live in an oven where the ambient temp would exceed 120 degree F in the shade. All of my cars utilize R134a. I just checked the blowing air temp, outside temp was about 100 degree F. My 2g is blowing about 59~61 degree F air. My daily 2004 civic is blowing 55~58 degree F air.

The issue isn’t R134a, it’s using R134a in a system designed for R12 like on the 1G’s. Supposedly the condenser and system doesn’t work as good using R134a because the condenser is too small and etc.

I’m curious if that’s BS or if it’s true. I know R12 cools amazing but wondering if it’s just hype.

I was using R134a in my 1g too, because actually where I live has no option. My 1g was blowing ice cold air with R134a until I removed the a/c at least.
But if you are capable to get R12, then why not going with it? No need to worry about any negative effect from R134a.

If it worked for you that’s good enough for me! Your climate is the ultimate version of my own. Easier just to go with 134a!

Why not use R12A ? ...From what I've read it a direct replacement for R12 and it compatible with the R12 lubricant ...I plan on trying it soon as i get the fittings to adapt and a new dryer installed

Here is what i know about it. You have to get your system clean to do a conversion. About the cooling r134a is capable but it is not equivalent. I worked out the math on it when I was in school. R134a requires higher pressures to achieve the same results. In a system designed for r134a its fine. Retrofit will not perform as well objectively. That being said I converted my 1g. I was easily comfortable. When it was r12 I could've hung meat in there. I would run r134a unless I had a cheap source of r12 and for sure only if my system was brand new. R12 is too expensive to lose. I vote r134a.

I considered it but R12A is a butane/propane mixture. I didn’t wanna risk an explosion in the engine bay if there was ever a leak.

I live in Florida after after checking my r12 level, which checked out fine, told my compressor was weak , it isn’t a problem,I had my AC CONVERTED TO 134a and it now blows colder than ever.
Just find someone that has worked on a DSMs
