Yes, an orifice tube in a car's air conditioning system can go bad if too much refrigerant is used to recharge the AC system. The orifice tube is designed to control the flow of refrigerant through the system, and if too much refrigerant is added, it can put extra strain on the orifice tube. This can cause it to become clogged or damaged, leading to issues with the AC system's performance. It is important to follow the manufacturer's specifications for refrigerant levels when recharging the AC system to avoid causing damage to components like the orifice tube.
