During the use of a car air conditioner, dust and moisture accumulate inside the air ducts and evaporator box. These impurities can easily mold and breed bacteria, leading to unpleasant odors. Therefore, it is necessary to clean the air conditioning system regularly. Below are some related tips on car air conditioner maintenance: 1. Regularly replace the filter: After using the air conditioner for a period of time, it is essential to clean it and replace the air filter regularly to extend its lifespan. 2. Maintenance of the car air conditioner's liquid storage tank: The liquid storage tank should be replaced after two years of normal use. Whenever the pipeline is disassembled for repair or cleaning, a new liquid storage tank should be installed. 3. Regularly check the refrigerant and refrigeration oil: Since the refrigerant used in modern cars is highly permeable, even a well-functioning refrigeration system can experience reduced cooling efficiency due to insufficient refrigerant caused by prolonged use.
