How to Clean the Car Air Conditioner?
2 Answers
Methods for cleaning the car air conditioner: First, clean the air filter, then clean the air ducts, followed by cleaning the evaporator. During the cleaning process, appropriate replacements can be made based on the condition of the components. The car air filter can separate solid impurities such as dust, pollen, and grinding particles from the air, and it can also absorb moisture, soot, ozone, odors, carbon oxides, SO2, and CO2, providing strong and long-lasting moisture absorption. The air filter for most car models is located in the glove compartment on the passenger side. Owners who are unsure can refer to the car manual for its location. The air filter can be removed for replacement or simply cleaned, as its cleanliness directly affects the interior environment of the car. For cleaning the air ducts, a specialized car air conditioner cleaner can be used, which not only cleans more thoroughly but also has a sterilizing effect.
Cleaning the car's air conditioner is actually quite simple. I often do it myself to save money and convenience. First, remove and replace the cabin air filter, usually located under the windshield or inside the glove compartment. Replacing the old filter with a new one removes most dust and mold. Next, buy an air conditioner cleaning spray and spray it into the external air intake. Start the engine, turn the air conditioner to maximum fan speed, and set it to recirculation mode, letting the spray circulate for 10 to 15 minutes to disinfect the ducts. After finishing, stop the car and clean any residue—it usually takes just an hour or two. Remember to do this every spring, as the moisture accumulated in winter can breed bacteria, causing odors and affecting cooling efficiency. I recommend using eco-friendly cleaners to avoid corrosion. Beginners who find it troublesome can search for tutorial videos online—all you need are a screwdriver and the spray.
