What Causes the Unpleasant Odor When Turning on the Car Air Conditioning?
1 Answers
Car air conditioning emits an unpleasant odor due to mold growth in the evaporator box and ventilation ducts. Air entering the car is cooled or heated by passing through the evaporator box before being blown out as warm or cool air through the vents. During use, bacteria, dust, and even insect remains inevitably enter the evaporator box and ventilation ducts. Over time, this leads to odors when the air conditioning is in use. Solutions to eliminate car air conditioning odors: 1. Choose an open, sunny area, open the car doors, set the air conditioning to maximum external circulation (without turning on the cooling function), and let it blow for 6 minutes to expel dust; 2. Replace the air conditioning filter promptly; 3. Clean the air conditioning system to remove mold from the evaporator box.
