How to Deal with Odor in Car Air Conditioning?

[StJonathan]

Here are the solutions for odor in car air conditioning: 1. Replace the air conditioning filter: The air conditioning filter is a crucial component of the air conditioning system, as all incoming air passes through it. Replacing it can help reduce odors. 2. Replace the air conditioning evaporator: The evaporator is where condensation forms after the air is filtered in the air conditioning system. Bacteria can easily grow and multiply here, so replacing it can also help reduce odors. 3. Air fresheners: You can purchase some fragrant air fresheners to place in the car, which can naturally help eliminate odors.

I've encountered this issue too. At first, I thought it was just ordinary mildew smell and didn't pay much attention. Later, I found that every time I turned on the AC in summer, it made me cough badly. After a special trip to the repair shop, I discovered that the AC evaporator had grown a thick layer of mold. The mechanic said this is the most common situation because the condensed water left on the evaporator after parking becomes a breeding ground for mold. Now I've developed a habit: turning off the cooling five minutes before reaching my destination to let the fan dry the evaporator. Additionally, I change the AC filter before each seasonal change—it only costs a few dozen yuan but works wonders. If the smell is particularly strong, you can buy an AC cleaner spray and apply it through the air intake vent; it's something you can do at home yourself, saving you three to four hundred yuan in cleaning fees. Also, don't leave food scraps in the car, as they can easily breed bacteria.
