How Often Should a Family Car Be Recharged with Refrigerant?

[SanJonathan]

For average-performance cars, the refrigerant recharge cycle is shorter, requiring a recharge within two years; for high-performance cars, the cycle is longer, allowing up to eight years before a recharge is needed. Methods to determine whether a refrigerant recharge is necessary are as follows: 1. Continuous bubbles in the sight glass during normal air conditioning operation: This indicates that the refrigerant level is insufficient and needs timely replenishment. 2. No bubbles in the sight glass during normal air conditioning operation: This means that a certain amount of refrigerant needs to be released, indicating an overcharge. 3. Brief bubbles appearing in the sight glass during normal air conditioning operation: This shows that the refrigerant level is within the normal range.
