Releasing R12a From A/C System
Hi. I recharged my A/C system a few weeks ago, but I overcharged it slightly (I charged it up to 45 psi, which is the border line between acceptable and too high, according to Duracool). So I have three questions: Will this cause any problems if I keep it at this high of a pressure? And, if I do have to lower the pressure can I just release some of the R12a that I used for the recharge into a paper towel or something and throw that out? The system was completely empty before the recharge, so there's only R12a in there (no R12 or R134a). And, the can of R12a says it's a natural coolant that isn't ozone-depleting, so I'm guessing it'd be alright to release it myself? Also, what kind of problems would occur if the system had been overcharged any further, like 60 or 70 psi?
