Car refrigerant replacement cycle, how often does the car air-conditioning refrigerant add

During the use of the car, there are bumps in the road, and over time, most parts of the car will have varying degrees of aging. The sealing performance of the storage refrigerant container will become worse, and the leakage of the coolant will occur. The reduction will directly lead to the deterioration of the cooling effect. Therefore, it needs to be supplemented. So, how often do you add refrigerant for car air-conditioning?

There is no fixed replacement cycle for automobile refrigerants. This needs to be judged according to the specific usage of each automobile and the cooling effect of air conditioning. If the car air conditioner has poor cooling effect, it needs to be checked. If it is caused by the lack of coolant, it needs to be refilled in time. As long as the car is properly maintained, in the usual driving environment and personal driving habits, there is generally no need to add car air-conditioning refrigerants within three to four years.

However, there may be slight leaks in the car air-conditioning pipes and condensers, which will accelerate the loss of coolant, so regular inspections are required. Even if the coolant does not leak, there will be natural loss. It is generally recommended to check once every 2-3 years. If there is any shortage, fill it in time.

There are two ways to add fluoride to automobile air conditioners, namely high-pressure side filling and low-pressure side filling. The high-pressure end is filled with liquid, which is safe and fast, and is suitable for the first filling of the refrigeration system; the low-pressure end is filled with gas, and the filling speed is slow, which is usually used for replenishment.
