What Causes Odor When Turning on the Car Air Conditioning?
1 Answers
Car air conditioning odors are caused by: 1. The air filter not being cleaned for a long time, combined with humid weather during rainy seasons, creates a damp and warm environment on the filter, leading to mold growth and a musty smell; 2. Outside air flowing through the air conditioning system pipes may leave small amounts of residual moisture that mixes with dust in the air. If not cleaned for a long time, this can also lead to mold and produce a sour, rotten odor. Here are some solutions to address car air conditioning odors: 1. Regularly clean the air conditioning system or replace the air filter to reduce mold growth; 2. Master the correct method of turning the air conditioning on and off. Generally, it is best to turn off the air conditioning 5 minutes before parking, then switch to natural air to allow the car's temperature to rise quickly. This prevents condensation from forming in the air conditioning pipes due to temperature differences after parking, keeping the pipes dry and blocking mold and fungus growth; 3. Use natural air fresheners, such as placing fruits like pineapple, lemon, or apple in the car to help eliminate odors; 4. Frequently use the AUTO button on the air conditioning panel to maintain a relatively stable temperature inside the car, ensuring comfort while also preserving air quality.
