I just bought an A/C kit to refill the A/C system in my car. However, I need to have the rest of the refridgerant removed. My A/C is working, but there is no cold air coming from the vents when I turn it on.

I'm thinking I need to have whatever is left in the system removed by a specialist. My question is:

Is it possible to just refill it without removing the old R12 refridgerant? If the old and new refridgerant is mixed, is that safe? (it won't create a poinsonous gas cloud that'll suffocate me, will it?)

I bought a kit at Wal-Mart for an R13 A/C system. My car is running on R12 system.

Thanks in advance!

You have to have a license to buy R12 in the communist state of California.

All of the U.S. right?

Don't know. The OP seems to have bought some.

Sorry, I'll clarify. I bought a kit at Wal-Mart for an R13 A/C system. My car is running on R12 system.

First off..you have to be licensed to buy R-12, R22 (RIP), etc... That is national regulated due to the EPA.

Don't just blow the R-12 in the air..as it is a huge reward for anyone that can prove you did it.

Don't mix R's... :)

What the hell is R-13? Do you mean R-134A? That is the commonly available over the counter refrigerant available today. It is not compatible with R-12 in any way shape or form. R-12 uses a mineral based oil for lubrication and R-134A uses a synthetic and the two should never be mixed. You need to totally flush the system of the old oil with denatured alcohol before you recharge it with the R-134A and you must also add the correct amount of oil for your application. If you have to ask how to do this on ATOT you should probably not be touching it in the first place.

If you get a chance, taste some of the R12 that comes out of your old system.
