What Causes the Foul Odor in Huansu S5's Air Conditioning?
2 Answers
Huansu S5 air conditioning odor reasons: 1. The evaporator in the car's air conditioning operates in a cold environment, and when it encounters relatively hot external air, condensation forms. 2. The damp conditions of the evaporator and ventilation ducts, along with accumulated dust, create an ideal breeding ground for mold and fungi. 3. Once mold and fungi find a suitable environment, they quickly multiply into colonies, producing foul odors as they decompose organic matter during this process. For mild car air conditioning odors, you can drive the car into the sun on a sunny day, set the air conditioning to the warmest setting, turn the fan to maximum, and leave all doors and windows open for about ten minutes. The benefits are: 1. Utilizing UV rays to disinfect the interior; 2. Allowing hot air to thoroughly circulate and flush out dirty air from the ventilation ducts. The advantage is that it costs nothing to eliminate the odor.
I've been driving the Huansu S5 for over two years now, and the issue of smelly air conditioning is really annoying, especially that distinct musty odor. After some research, I found that the most common cause is mold growth inside the evaporator. When the AC cools, moisture condenses, and if it doesn't dry thoroughly after parking, the dampness leads to bacterial growth and foul smells. Additionally, if the cabin air filter hasn't been replaced for a long time, it accumulates dust and mold spots, releasing odors when the air blows. Last time, I went to a repair shop for a deep cleaning—they cleaned the evaporator and ducts and replaced the filter. It took some time, but the effect was immediate. For regular maintenance, I suggest turning on the external circulation with high fan speed for a few minutes before parking after using the AC in summer to help it dry out. Also, replace the filter regularly—once a year is enough—to avoid costly major repairs. Keeping the cabin air fresh not only feels comfortable but also prevents health issues caused by bad odors.
