How Long Does Car Air Conditioning Refrigerant Last?

[RachelMarie]

Car air conditioning refrigerant can last for two to three years. Below are specific details about recharging car air conditioning refrigerant: 1. Precautions: There are two methods for recharging refrigerant—high-pressure side charging and low-pressure side charging. These are two completely different methods; one involves adding liquid, and the other involves adding gas. High-pressure side charging is typically used for the initial recharge, as it involves adding liquid, which is faster and safer. Low-pressure side charging involves adding gas, which is slower and is generally used for top-ups. 2. Temperature should be appropriate: Setting the temperature too low can affect health, so it's important to adjust the air conditioning temperature appropriately. The most comfortable temperature for the human body is between 20°C and 25°C. Above 28°C, people feel stuffy, while below 14°C, they feel cold. Therefore, the car air conditioning should maintain an interior temperature between 18°C and 25°C. Excessively low temperatures can easily make people sick.
