What Causes the Foul Smell in Haval H9's Air Conditioning?
3 Answers
Here are the reasons why the air conditioning in Haval H9 produces a foul smell: 1. Prolonged use of the air conditioning can lead to the accumulation of dust in the indoor filter and copper coils. When this dust reaches a certain level, it produces an odor. When the air conditioning is turned on, this odor is dispersed into the air. 2. After cooling or heating, the indoor unit of the air conditioning system often generates moisture. If the air conditioning is turned off immediately without a drying or anti-mold function, the moisture remains inside, leading to the growth of mold over time, which produces a musty smell. Here are some methods to eliminate the foul smell: 1. If the air conditioning has been used for a short period and only has dust on the panel and vents, simply wipe it clean, open the panel, remove the filter, and rinse it with clean water. 2. If the air conditioning has been used for a long time and the user cannot clean it easily, it is necessary to contact the after-sales service for a thorough cleaning to ensure the air blown out is healthier and fresher.
When I turn on the air conditioning in my Haval H9, that awful smell is really annoying. It's usually because the cabin air filter is too dirty, clogged with dust, pollen, and bacteria. Over time, the evaporator in the air conditioning system tends to develop mold, especially after summer rains when residual moisture leads to mold growth, causing unpleasant odors. Additionally, accumulated dust in the air conditioning ducts or the presence of dead small animals like rodents can also produce foul smells. From my experience, regular inspection and cleaning are essential. I recommend replacing the cabin air filter every six months and turning off the air conditioning a few minutes before parking to let the blower dry out the system and prevent moisture buildup. If the smell persists, take the car to a 4S dealership for a thorough cleaning of the evaporator—don't compromise driving comfort. Following these steps should mostly eliminate the odor. Remember, neglecting this issue may allow bacteria to accumulate further, affecting your driving health.
When I encounter the foul smell in my Haval H9's air conditioning, my biggest concern is health issues. Those unpleasant odors often come from bacterial and mold growth in the AC system, especially in the moist environment of the evaporator, which becomes a breeding ground for bacteria, blowing out air with a musty smell. With children riding in the car, such air can easily trigger allergies or respiratory discomfort, so it needs to be addressed promptly. Additionally, poor filtration by the AC filter and the accumulation of external odors or dust in the ducts can also cause problems. I've developed a habit of regularly replacing the filter and spraying disinfectant to maintain cleanliness. If the smell is severe, don't wait—take it directly to a professional repair shop to check the system's sealing to prevent minor issues from turning into major problems that affect the whole family's travel. This way, you protect the air inside the car and drive with peace of mind.
