If it needs a recharge, that means you have a leak in the system somewhere. The freon lines are supposed to be sealed, so you never need to recharge unless there's a leak.
Find the leak, fix the leak. By the time you've done that, all of the R-12 will be gone (if it isn't already), and you can start fresh with R-13A.
