I have a 2014 Dodge Charger SE and recently I've tried to refill my AC as I noticed it's not blowing as cold anymore. When I go to refill it I noticed that the pressure is not going up. I empty about half the can and it still stays around 10 PSI. I made sure that the compressor is running and that I have the AC at max. I could hear how the can was emptying and I also felt how the air around me got cold whenever I would add some refrigerant but the inside didn't get cold. And now I also hear a small noise whenever I turn on the AC. Does anyone know what could potentially be wrong? Also my car uses R1234YF instead of R134 if that makes a difference (I made use to check). I don't want to waste a can as it is expensive

You have a leak somewhere in the system. Find it and repair it before spending any more money on refrigerant.
I tried looking for it by adding some UV dye but can't seem to find it. And the noise sounds like if there was a gas leak so it could potentially be a leak. I can hear it from the inside of the car and around the back of the engine on the right side whenever the AC is running.

My guess would be the evaporator inside the HVAC box. The one on my 2011 developed a leak and had to be replaced.
