Yes I know you are supposed to use the low side port, but here's the situation. So a few weeks ago, I had my system retrofitted and recharged. I noticed that the mechanic who did the retrofit placed the high side r134a fitting on the r12 low side valve and the r134a low side fitting on the r12 high side valve. So I guess the guy did that because that's the only way the fittings would screw on, but now I have to recharge my car's a/c through the high side port. Will that damage anything? I just recharged it today because the air was getting a little warm.
