The season has changed. It’s time to give your car air conditioner a comprehensive maintenance.

1. Check whether the refrigerant is sufficient. This can be measured by detecting the temperature difference between the dryer inlet and outlet lines, or by a manifold pressure gauge.

2. Clean the condenser frequently. Some car owners often flush the condenser with water pipes when using air conditioners in summer. This is correct. Since cleaning the car condenser surface facilitates the dissipation of heat energy to the outside world, regular cleaning of the condenser surface can greatly improve the cooling effect of the air conditioning system.

3. Frequently clean dust and dirt from the air outlet and cab. This is not only beneficial to the appearance of the car, but also to the health of the driver and passengers.

5. Check whether the compressor belt is intact. If the surface of the belt is in contact with the groove of the pulley and the side is bright, and there is a "squeaking" sound when starting the air conditioner, this indicates that the belt is seriously slipping and the belt and belt should be replaced. pulley. If the belt is too loose, it should be adjusted, otherwise the cooling of the air conditioning system will easily deteriorate.

6. Check whether there are oil stains on the hoses and accessories of the air conditioning system. If leakage is found, consult a maintenance technician in time for a solution.

Notes

When using the car air conditioner for the first time during the season change, it is best to disinfect the air conditioning system. This is because the air conditioning system will breed fungus and mold when it is "off" for a long time, which not only makes the air emit an unpleasant mold smell, but is also harmful to the health of people in the car. This work can be done at a repair shop or you can do it yourself by purchasing a special spray for disinfection and deodorization.
