How often should a car air conditioner be cleaned?

Car air conditioners should be cleaned once a year, but the specific cleaning interval depends on the air environment the vehicle frequently operates in. If the environment is poor, the cleaning interval should be shortened accordingly. If a car air conditioner 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 occupants. It is recommended to have professionals at a 4S shop perform the cleaning. The car air conditioner is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle cabin to the optimal state, providing a comfortable environment for passengers and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device.

As a friend who often drives, I think car air conditioning cleaning is not something to be taken lightly. I personally clean my car's air conditioning every year and a half or so, mainly acting when I notice an odd smell when using the AC. Since I use the air conditioning frequently during daily commutes, especially in summer, it’s prone to dust buildup and the growth of odor-causing substances. If not cleaned in time, it can easily trigger allergies or respiratory issues. If driving in dusty areas, it’s best to clean it six months earlier, otherwise, breathing in the dust can be uncomfortable. It’s best to go to a professional shop for cleaning—they use sprays to treat the evaporator and ducts, which is cost-effective and works well. Remember, health is the most important; don’t neglect air conditioning hygiene.

After driving for several years, I've come to understand the importance of regular air conditioning cleaning. It's generally recommended to have a professional cleaning every two years, but if the car is older or used frequently, it's advisable to shorten the interval to once a year. I've experienced the troubles caused by neglecting this: mold growing in the AC system, musty air blowing out, and constant coughing while driving. When taken to a shop, the technician will thoroughly clean the ducts and filters, killing bacteria. It's also important to pay attention in daily use, such as changing the filter more often when parked under trees with lots of leaves. The cleaning interval depends on the driving environment, with more frequent cleanings needed in humid southern regions. Don't underestimate this; keeping the AC clean enhances the driving experience and helps prevent illnesses.

I pay special attention to the air quality inside the car because my child has a somewhat sensitive constitution. If the car's air conditioning system is not cleaned, accumulated dust and bacteria can blow out pollutants when the AC is turned on, triggering allergies or respiratory discomfort. Therefore, we clean our car's AC system almost every year before summer. If left uncleaned for too long, odors and dust will accumulate significantly, but it becomes fresh immediately after cleaning. For frequent use, such as long-distance driving or being stuck in urban traffic jams, it might be necessary to check every six months. In short, maintaining a regular cleaning schedule is a key health measure—I recommend not waiting until problems become severe to take action.

DIY-savvy car owners like me can handle air conditioning cleaning on their own. I purchase specialized cleaning agents from repair shops and perform the cleaning every eight months or when I detect odors. The simple steps involve starting the car, turning the air conditioning to maximum fan speed in external circulation mode, then spraying the cleaning agent into the air intake and evaporator area, letting it run for ten minutes to blow away dirt. Cleaning or replacing the air filter is also crucial—either install a new one or clean the old filter. This approach saves money and time while avoiding the hassle of visiting a shop. The cleaning frequency depends on usage; if driving in dusty environments like construction sites, double the frequency to about twice a year. DIY cleaning is both reliable and economical.
