So i was trying to recharge my a/c and suddenly after while while it was getting to a better pressure i seen some smoke so i cut my car off and suddenly i hear this loud noise could someone tell me what’s going on

 

well the video won’t upload but it’s a loud like blowing noise

 

You overfilled and it leaked out of an o-ring?

 

The noise you heard was the pressure relief valve in the high side if the system. The "smoke" you saw was vapor refrigerant that the relief valve released because it was over charged.
