What Causes White Debris to Blow Out When the Car Air Conditioner is Turned On?
2 Answers
Air conditioner blowing white debris is due to excessive dust or rust particles from the pipes. Here is additional information: 1. Introduction: Car air conditioning refers to the air conditioning device installed in a vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Air conditioning has become one of the indicators for measuring whether a car is fully equipped. 2. Composition: Generally includes refrigeration units, heating units, and ventilation units. This combined system makes full use of the limited space inside the car, with a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
I recently encountered the same issue where turning on the car AC spewed out a lot of white debris. After checking, I found it's mostly due to mold growth on the AC evaporator. The damp and stuffy interior of the AC system is prone to mold if not cleaned regularly, and these small particles are actually mold spores. Inhaling them poses health risks, potentially causing respiratory allergies or discomfort, especially for those with asthma. The best solution is regular AC cleaning—recommended quarterly checks on the filter, replacing it if dirty, and using specialized disinfectant sprays on the evaporator. Don’t let it worsen, or the entire air duct could get contaminated, drastically reducing air quality while driving. A professional auto shop can handle this in minutes for a thorough clean. Safety first—address the problem promptly if spotted.
