What happens if my system is overcharged?
When you overcharge your system you a pressure cut off switch is activated to stop your A/C compressor from running. This in turn will cause your system to blow warm air. If this happens you will need to go to a car A/C professional and have the excess refrigerant recovered from your system. Remember it is illegal to vent refrigerant from your system, and the government can impose stiff fines for failure to follow these rules
