Does a car's air conditioning need to be cleaned every year?

Car air conditioning needs to be cleaned annually, but the specific cleaning interval depends on the air environment the vehicle frequently operates in. If the environment is poor, the cleaning cycle should be shortened accordingly. If the car's air conditioning is not cleaned for a long time, it will accumulate a lot of dust, causing secondary air pollution. Inhaling this polluted air can affect the health of the users. It is best to have professionals at a 4S shop perform the cleaning. The car air conditioning filter should be cleaned at least once a month, and the cleaning cycle can be adjusted appropriately based on usage frequency and environmental conditions. If the filter is used for more than 2,000 kilometers, the activated carbon filtration function in the air conditioning filter will diminish, at which point it is recommended to replace the air conditioning filter.
I don't think car AC cleaning is that rigid. It doesn't necessarily need to be done every year, but regular inspections are crucial. I once experienced a musty smell when using the AC in summer, and it turned out to be accumulated dust and mold in the ducts. After cleaning, the air became much fresher and more comfortable to breathe. The key is to base it on usage conditions – for example, if you drive frequently in polluted urban areas or your car interior is often damp, an annual cleaning is recommended. Don't neglect the blower and filter either; when they get dirty, they can affect the entire system's efficiency. Spending a little on maintenance helps prevent problems and can extend your AC's lifespan. Personally, I make it a habit to check before every summer to avoid discomfort while driving.
