Correct steps for cleaning a car's air conditioning system: 1. First, locate the air circulation inlet connected to the vents. This is usually found on the right side at the base of the windshield or beneath a central cover panel. 2. Set the air conditioning to maximum fan speed and switch to external circulation mode. 3. Open the inlet cover using your hand or a screwdriver. 4. Attach the nozzle provided with the cleaning solution and spray into the inlet. Spray again after a few seconds in intervals rather than continuously. The blower will draw the cleaner into the ducts. Change the circulation mode to ensure all ducts are cleaned. 5. After 15 minutes, turn off the air conditioning. The cleaner will drain out with the condensate water. When no more condensate flows out, turn on the heater to evaporate any remaining cleaner inside the system, and leave the windows open for ventilation. 6. The car's air conditioning cleaning is now complete.
The correct way to clean a car's air conditioning is simple but requires attention to detail. First, use a specialized air conditioning cleaning spray and apply it to the air intake and vents. Then, start the car and run the air conditioning at maximum fan speed for 10 to 15 minutes to circulate the cleaner and remove mold and bacteria. Keep all windows open for ventilation during this process. After finishing, don't forget to replace the cabin air filter, which traps dust and odors—usually costing just a few dozen yuan. I do this every year, cleaning once during summer when the AC is used frequently to prevent musty smells inside the car, making driving much more comfortable. Remember not to use regular household cleaners, as they can corrode the system. Before cleaning, check the filter's condition—if it's dirty, prepare a new one in advance to avoid making two trips. Doing it yourself saves money and can be more effective than going to a repair shop.
