In late summer and early autumn, many car owners reported that the air conditioner had a peculiar smell. This is because there is water in the evaporation box. If it cannot volatilize for a long time, it will become moldy and blow into the compartment with the air flow of the air conditioner. If the filter screen is moldy, it can be removed and cleaned with water, which is simple and economical. However, if it is made of activated carbon, this method cannot be used. It is also very simple to avoid this problem. First, when the weather is not hot, open more windows for ventilation; Secondly, when driving with the air conditioner on normally, turn off the refrigeration pump before reaching the destination, but keep the air supply function on. Let the natural wind blow for a while, and the water in the evaporation tank can be dried. Pay more attention at ordinary times. There is generally no mildew in the air conditioner.
In addition, there is more rain in summer, and cars often walk on some wading roads, resulting in a lot of sediment on the lower part of the air conditioning condenser. Over time, the condenser will rust, thus shortening the service life of the air conditioner. The routine cleaning cycle of vehicle air conditioner is once every half a year. During cleaning, pay attention not to knock down the radiator of condenser, let alone damage the pipe.
The season change is a good time for dust removal. It is recommended that the owner go to the maintenance shop to conduct a comprehensive inspection of the air conditioner, so that the air conditioner can work well in cold winter to ensure the freshness of the air in the car.
