I guess this has to do with cooling. I have a 30lb jug of R12 and a set of gauges, anyone know how to fill the system up up?

 

Are you certified to work on R-12 systems.

 

No, but the R12 was bought before 1994, so it is legal. It is my dad's jug but all of his cars are running R134a so I figured Id get some use out of it. My system is leak free and works fine if that's what your worried about, I needed it released when I did the motor swap.

 

I know you need the right tools to do it, i dont know what all because i've never tried...Its supposedly not really hard at all though. Of course, you have to be carefull not to leak any of it, you dont want to breath that crap in. Before you throw it in yourself, try calling pep boys? Or whatever. Local amaco service station.....Normally the bulk of the bill is the price on the freon, if you supply your own freon, they may only charge you like $10 to pump it in while you wait

 

Holy crap do you know how much R-12 cost these days. And you have a 30lb jug of that? Wow. All I know is that you need different gauges than R134a. Its not that difficult to do just make sure you know which plug to stick it in. I'm not too sure but I'm sure someone can clear that up.

 

just make sure u don't have any leaks. cause that would be a waste!! also i think it can be illegal if u are working with that stuff without a license, even if u did buy the freon when it was legal. its still illegal to let it escape into the atmosphere. so just make sure no one is watching but i would think about trying to sell that stuff to a shop or something, might get quite a bit for it..

do you have the equipment to evacuate the system properly? just curious

 

I just got certified today, I figured what the hell, something to put on my resume. I also got a few articles on the procedure. Before I sneak my dad's R12, i will prob look at some prices at shops because like you guys suggested, he wants to sell it when its really rare.
FYI It IS legal to top off a known leaky system im most places except, of course, california and a few others. I though that was interesting.

 

if he has it to sell it, you should remind him he has it, and advise him to look into selling it now. You know, the new stuff (R13A is it called?) isnt THAT expensive, and really neither is the conversion to it. As all the old R12 gets converted over, the demand for it drops, I beleive it may have dropped a bit allready. Eventually, no one will want that old stuff anymore.

 

Thats pretty awsome that u got certified in it. Where did u take the test? is it ASE cert.?

I didn't know about it being legal to top off a known leaky system. But then again i think that is cause texas is one of those states where it is illegal. I know the guy at the shop near me told me that it was a $10,000 fine if he didn't check for leaks first and the system was leaking..

But geez its been so long since i have had A\C..

 

my grandfather helped me top off my r12 when i got my car however when i went to use it a few weeks later the compressor was cycling again too much, i guess i have a leak

so byebye a/c most likely....

 

ASE may be able to train and test, but the USEPA controls the certification process. There are a lot of places to get the training and take the exams, including many trade schools and community colleges. You pay taxes for those colleges, so you might as well take advantage of them.

For replacing the refrigerant, you'll need an R-12/22/502 manifold gauge set and hoses. You'll also need to leak or vacuum test the system, and if the system has been totally empty for any length of time, you'll need to replace the dessicant dryer and add the appropriate amount of refrigerant oil before charging.

 

R12 has alot more power than that new crap. I would never switch over form R12.
