To remove heated air from the cabin compartment, the air conditioning system runs continuously, transferring refrigerant through a sealed system. Your car?s air conditioner won?t cool as effectively as it used to when this system loses refrigerant; at this point, you should take it to a specialist who can diagnose the issue and replace it without speculation.
