How often should the air conditioning in a new car be recharged with refrigerant?

[SanJessica]

There is no fixed interval for recharging the refrigerant in a car's air conditioning system. The need for recharge is primarily determined by the effectiveness of the cooling. Precautions for refrigerant recharge: When the refrigerant (Freon) in the cooling system decreases due to leakage, leading to a significant drop in cooling efficiency, it is necessary to replenish or replace the refrigerant. Before replenishing, the cause of the refrigerant leakage must be identified and repaired. Otherwise, the newly added refrigerant will leak again. Precautions for using car air conditioning: Car air conditioning systems are generally unused during winter. Before initial startup, check the belt tension. After prolonged use, the system should undergo dust and bacteria removal. Observe the engine coolant temperature after running the air conditioning for a while. If the temperature rises abnormally, stop the air conditioning immediately. Methods for car air conditioning maintenance: Regularly check the refrigerant and compressor oil, adjust the low-pressure side pressure to 2-3 bar and the high-pressure side pressure to 15-25 bar, clean the condenser, and wash the evaporator surface.
