How to maintain car air conditioning

1、 Replace the air conditioning grid

The first gateway to air conditioning is the air conditioning grid. Do car air conditioning grids need to be cleaned or replaced in the hot summer? Experts suggest that although it is recommended for car owners to replace the air conditioning grid during regular maintenance in the spring, if the car's air outlet suddenly decreases or the noise becomes loud, or the air conditioning cooling is not obvious, it is necessary to consider replacing the air conditioning grid.

There are many plum rains in spring and rainstorm in summer. Many moisture laden dust, cotton wool, leaves and other impurities will accumulate on the evaporator when passing through the air conditioning grid. In addition to making the air conditioner work poorly, this is also the reason for the odor in the car. To eliminate odors, on the one hand, specialized disinfectant can be sprayed, and on the other hand, car owners should replace the air conditioning grid once a year. When there is a low air output or a loud noise when turning on the air conditioning, it is necessary to consider replacing the air conditioning grid.

Try not to do "steam disinfection" in some roadside car beauty shops, as this can cause damage to the air conditioning system, as steam disinfection generates a large amount of water, and the water not discharged in a timely manner can cause damage to circuit equipment.

2、 Cleaning the evaporator

If the air conditioning grid is replaced for a short period of time and there is low wind or odor, then it is necessary to clean the evaporator. Experts say that two types of potions are often used during the cleaning process of air conditioning grids. One is a disinfectant for the air conditioning grid, and the other can be used to remove impurities such as dust and hair accumulated on the evaporator through ultrasonic atomization or high-pressure methods. These impurities, after being ultrasonic atomized, will be discharged through the air conditioning drainage outlet. After a thorough cleaning, the air conditioner can function normally and blow out bursts of clean cool air.

The evaporator is inconvenient to repair and does not need to be cleaned frequently. Therefore, to ensure the normal use of the air conditioner, it is necessary to pay attention to the cleaning and replacement of the air conditioning grid. Generally, sterilization is done once a year or at the same time as replacing the air conditioning grid.
