AC recharge

[bertrenolds5]

My ac works a little, the air is not very cold so I figure I need to recharge it. Do I really have to have someone clean all of the r12 out, or can I just get a can of 134a and an adapter and fill her up?
Anyone know where I could go to get a good price if I have to have it sucked out?

When I lived in AZ, I got my talon converted over to a refrigerant called Freeze 12. The only thing they had to change was the fitting on the AC line, and then they removed the old stuff and put in the new. And the Freeze 12 is supposed to be real cheap. I haven't seen it up here though, so not sure how I'm going to recharge it when that time comes.

There's a link to what I am converted to. Supposed to actually be colder then R-134a, and a fairly easy conversion for older R-12 systems like ours.

R134A is really cheap and is available at all parts stores and even Walmarts along with the retrofit kits.

do I have to suck the old r12 out, or can I just get r134a and mix it with the r12?

I just mixed it right in, no problemo.

Someone told me your lines will corrode if you mix 12r and 134a? I was reading 134a is apparently the only approved stuff to mix with 12r I think, is that true? Now I gotta find someone with a hose and guage and converter to 134a. Can anyone help me out?

[Kracka]

Sweet, No I gotta find someone with a hose and guage and converter. Can anyone help me out?

Walmart, Autozone, Checker, O'Reillys, etc. The conversion kits are cheap and are usually boxed with everything you need including the cans of cold stuff.

You may want to look into the reason it needs to be charged, such as a leak. Just so your not disappointed after the fact.

Did the A/C become less affective slowly over time or all of a sudden over night? If slowly over time, considering its a '91, I wouldn't worry too much about a leak and just refill it whenever it needs it since the stuff is so cheap. If it happened very quickly you probably have a junk seal and should get some of the leak tracer dye.

The car sat a few years before I got it and when I got it the ac was weak but it did and still does work a little so I don't think there is a leak. I already have 2 cans of 134a, I just wanted to make sure I could mix it. I put it in the lower input on the compressor housing right? Some one has to have a hose and adapter that I could use so I don't have to buy one, come on guys.
