What to Do When the Car Air Conditioner Emits Odors in Heating Mode?
1 Answers
The main reasons for odors when using the heater are external exhaust fumes, accumulated smells inside the car, placed air fresheners, as well as human sweat and body odor, which can enter the car's interior. When the air conditioner is used, these odors encounter the warm and moist surface of the evaporator, blending with the air, and are then released when the air conditioner is in operation. Methods to eliminate odors include: 1. High-temperature drying of the evaporator. 2. Minimize the use of acidic car air fresheners. 3. Use cleaning agents to sterilize the external circulation air ducts. 4. Reduce sources of odors inside the car as much as possible. 5. Alternate between primary and spare filters.
