What to Do When There's an Odor from the Car Air Conditioner?
2 Answers
Adjust the air conditioner settings to maximum airflow, enable external circulation, and turn on the A/C. Then, aim the cleaning agent connected to a hose at the air intake and spray it in cycles—spray for a few seconds, pause for a few seconds—until two-thirds of the bottle is used. During spraying, keep the cleaning agent upright; do not lay it horizontally or upside down. Afterward, run the air conditioner in each mode to ensure all air ducts are cleaned. The entire process should take 10-20 minutes. Below is an introduction to car air conditioners: 1. Introduction: A car air conditioner refers to the air conditioning device installed in a vehicle, capable of cooling, heating, ventilating, and purifying the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators of a car's functional completeness. 2. Types: Independent type (driven by a dedicated engine to power the compressor, offering large cooling capacity and stable operation but with high cost, large size, and weight, mostly used in large and medium-sized buses) and non-independent type (the air conditioning compressor is driven by the car engine, with cooling performance significantly affected by engine operation and poor stability, mostly used in small buses and cars). 3. Air Conditioner Layout: Different types of air conditioning systems have different layout methods. Currently, integrated heating and cooling air conditioning systems are widely used in cars. The layout typically combines the evaporator, heater radiator, centrifugal blower, and control mechanism into one unit, referred to as the air conditioner.
When I turn on the air conditioning while driving and there's an unpleasant odor, it feels really uncomfortable, especially in the summer when the car is stuffy and the air blowing out smells foul, like a moldy wet cloth. The reasons are usually quite simple: mainly, the air filter is clogged with dust, mold, or debris, or there's accumulated water in the ducts causing mildew. The first time I encountered it, I didn't pay much attention, but the smell grew stronger, and I even felt a tickle in my throat. The solution isn't difficult: first, check the air filter, which is usually hidden behind the glove compartment. If it's black and dirty, simply replace it with a new one. Buying a filter online that matches your car model costs just a few dozen yuan, and you can easily remove and install it yourself in just a few minutes. To clean the ducts, go to an auto parts store and buy a bottle of air conditioning deodorizing spray. Start the car's external circulation, turn the fan to the highest setting, and let it run for a few minutes to disperse the spray and kill bacteria. Before parking, don't rush to turn off the engine—turn off the AC but keep the fan running for another half minute to evaporate moisture and prevent mold. I replace the filter every six months, and now I never have to worry about driving with the AC on. Paying attention to these small details can greatly improve the driving experience.
