How Many Years Can a Refrigerant Charge Last?

[SanEloise]

Under normal circumstances, a refrigerant charge can last 3-5 years. It is generally recommended to inspect or top up the refrigerant every 2 years, and replace it every 5 years. This helps reduce the load on the air conditioning system, prolong its service life, improve cooling efficiency, and save energy. Typically, maintenance is required every 2-3 years. However, if the car's air conditioning system is functioning properly, refrigerant replenishment may not be necessary within 3 years. This applies to car air conditioning systems operating at normal quality levels, excluding inferior systems or used vehicles. If a noticeable decline in cooling performance occurs within two years, it is advisable to check for potential damage or leaks in the car's air conditioning system. Frequent refrigerant top-ups may indicate underlying issues with the air conditioning system or its components. The actual lifespan of a refrigerant charge depends on usage patterns, as natural depletion of refrigerant (coolant) occurs over time.
