Hissing sound of Air-condition gas Normal or NOT !

[ABDALLA]

Hi all
I Wonder if you noticed that hissing sound from inside when AC operated either for battery cooling or compartment cooling.
it happening to me science I received the car on January. in hot or warm weather or when rapid charging , I know how the compressor and valves sound is but this hissing make me doubt that firoin gas is not filled enough !

I can't say I hear a hissing sound inside the car with aircon on...

In an old car, I used to hear a similar sound almost akin to the refrigerant boiling within the system. I’d ask the dealer to see if the Aircon has the correct quantity of refrigerant since the car is new.
