Is it necessary to clean the car air conditioning every year?

It is necessary to clean the car air conditioning every year because during operation, 80% of the tiny dust particles and bacteria in the air can pass through the filter and enter the air conditioning system. These contaminants then combine with condensed water and clog the evaporator, which not only affects the cooling and heat dissipation efficiency of the air conditioning but also continuously accumulates dirt, breeding a large number of harmful microorganisms such as pathogenic bacteria, mites, and mold. When the car's interior air circulation system operates, some of these harmful bacteria and microorganisms can enter the cabin through the air vents, posing risks to the human respiratory system. Prolonged exposure to such conditions can severely impact the driver's health.

Having driven for over twenty years, I genuinely believe that cleaning the car's air conditioning system once a year is beneficial, especially if you frequently drive in dusty or odorous urban areas. The AC interior tends to accumulate dust and mold, which over time can emit unpleasant odors and even trigger allergies or respiratory issues. Regular cleaning maintains fresh airflow, enhances cooling efficiency, and creates a more comfortable cabin environment. Personally, I schedule a cleaning before each summer—it’s a modest expense of a few hundred yuan, where prevention outweighs repairs. Neglecting this can lead to component clogs or performance degradation, ultimately costing more. Routine AC maintenance also extends its lifespan and reduces major repair expenses, making it a worthwhile small investment habit.

As a commuter who often drives in the city, I don't think car air conditioning needs to be cleaned every year. I don't drive much, mainly short commutes to work, and the air conditioning is rarely used throughout the year, so dust accumulation is minimal. Cleaning costs several hundred yuan each time, and when the budget is tight, it's better to save where possible—as long as the air blows normally and there's no strange odor, it's fine. Unless there's a special situation, like a musty smell caused by humidity during the rainy season, cleaning every two years is sufficient. The key is to decide based on actual usage and the car's condition, rather than being upsold into spending more. Regular interior cleaning and ventilating by opening windows can also reduce the frequency of cleaning. The money saved can be used for other maintenance, making it more economical and practical.

As a family car user with children, I am particularly concerned about air quality. It is necessary to clean the car air conditioning annually because the enclosed space inside the vehicle can easily harbor bacteria and dust, especially around the air vents. If not cleaned, every time you turn on the air conditioning, you may notice a musty smell, which can cause children to cough or develop skin allergies. After cleaning, the air feels much fresher, making driving more comfortable. I recommend cleaning it once before summer starts and maintaining daily healthy habits. This simple and easy action can benefit the whole family.
