How often should vehicle air conditioning refrigerant be recharged?

[Jess]

Vehicle air conditioning refrigerant should be recharged based on actual conditions. Here is some information about vehicle air conditioning refrigerant: 1. Automobile refrigerant: There is no fixed replacement cycle for automobile refrigerant. This needs to be determined based on the specific usage conditions of each vehicle and the cooling effect of the air conditioning. If the vehicle's air conditioning shows poor cooling performance, it needs to be inspected. 2. Insufficient refrigerant: If it is caused by insufficient refrigerant, it should be replenished in time. With proper vehicle maintenance, generally it does not need to be recharged for three to four years.
