What happens if car AC is overcharged?
An overcharged AC will read higher pressures than normal and also higher temperatures. Your compressor will not be able to manage this amount of coolant in the lines which increases the pressure and that in turn makes the temperature go higher.
What are symptoms of overcharged AC?

What happens when you overfill AC refrigerant?
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.

How do you get air out of a car AC without a vacuum pump?
Step 2: Charge the low side valve
Now is a good time to adjust the low-pressure side of the A/C to 14 psi. Running the friction for a few minutes will bring the pressure on the high and low sides close to equilibrium.
