What are the repair and maintenance techniques for parking air conditioning?

The repair and maintenance of parking air conditioning are crucial for maintaining its efficient operation and extending its service life. Here are some key repair and maintenance tips:
Regular cleaning and maintenance: Regularly clean the condenser, evaporator, and ventilation system of the air conditioner to ensure that there is no dust or debris obstructing air flow. This can not only improve the operational efficiency of air conditioning, but also prevent the growth of bacteria and mold.
Check refrigerant level: Insufficient refrigerant is a common cause of air conditioning failure. Regularly check the level of refrigerant and add as needed. If poor cooling effect is found, it may be necessary to replace the refrigerant or check for leaks.
Replacing the filter: The air conditioning filter should be replaced regularly to prevent dust and pollen from entering the system. It is recommended to replace the filter every 3000-6000 kilometers based on the frequency of vehicle use and the surrounding environment.
Check the electrical system: Ensure that all electrical equipment is working properly and there is no damage or corrosion. If any problems are found, they should be repaired immediately.
Check the drainage system: If the air conditioning drainage system is blocked or damaged, it may cause mold growth and corrosion. Regularly inspect and clean the drainage system to ensure its normal operation.
Avoid prolonged use of the recirculation mode: Prolonged use of the recirculation mode may lead to a decrease in the air quality inside the vehicle. It is recommended to regularly switch back to the external circulation to update the air inside the car.
Regular inspection: For vehicles parked for a long time, it is recommended to conduct a comprehensive inspection before reuse to ensure that the air conditioning system is working properly.
Use professional maintenance products: There are many high-quality air conditioning cleaners, protectors, and filters to choose from, which can help maintain the air conditioning system and extend its service life.
The above are some basic maintenance and upkeep techniques that can effectively extend the service life of parking air conditioning and maintain its good operating condition. If unsure about certain operations, it is recommended to seek the help of professional technicians.
