Does the car air conditioning system need cleaning?
1 Answers
Car air conditioning systems do require cleaning. More relevant information is as follows: 1. The function of a car air conditioning system is to provide a comfortable and healthy environment for passengers. During the operation of the air conditioning, the evaporator absorbs heat from the car to lower the temperature inside. Due to its low surface temperature, it remains in a damp state, which makes it prone to accumulating germs, dust, and other debris, especially in vehicles without an air filter. While driving, a large amount of dust and dirt can enter the air intake of the air conditioning system, accumulating in the air ducts and on the surface of the evaporator. On one hand, this can block the ventilation holes of the evaporator, reducing airflow; on the other hand, in a high-humidity, enclosed environment, it can breed a large number of harmful bacteria. These bacteria float in the air inside the car as it circulates, causing symptoms such as dizziness, fatigue, and nausea. Prolonged exposure can lead to respiratory diseases, posing health risks. 2. If not cleaned for a long time, when you turn on the air conditioning, you may notice musty, smoky, or foul odors, which are the root causes of health hazards. Therefore, regular cleaning is essential, especially before using the air conditioning in summer and the heater in winter. Generally, cleaning every 40,000 kilometers is recommended, including the evaporator and air ducts, followed by replacing the air filter.
