The air compressor for the A/C unit may not operate correctly when the system is overfilled with refrigerant. This can actually cause the car itself to run roughly or even die in some cases.
What happens if you put too much freon in your car’s AC?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.

Lack of Cooling
The most evident symptom of overcharged AC is that it will not cool the car. Due to the overcharged status, the liquid in the system doesn’t have enough room to depressurize. As a result, it will not be capable of providing sufficient cooling in the interior of the car.
Will car AC work if overcharged?
