How Often Should Car Refrigerant Be Replaced?

[PeterFitz]

There is no fixed interval for replacing car refrigerant. Generally, when the cooling effect of the car air conditioner deteriorates, you can check if the refrigerant is insufficient and replace it. Refrigerant, also known as coolant or freon, is the medium substance used in various heat engines to complete energy conversion. These substances typically use reversible phase changes (such as gas-liquid phase changes) to increase power. The following is an introduction to car air conditioning: Car air conditioning refers to the air conditioning device installed in a car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The car's air filter can accumulate impurities over time, so cleaning and replacement are very important.
