What Causes the Odor When Turning on the Car Air Conditioner?

1 Answers

There are two main reasons for the odor in the car air conditioner: dirt accumulation on air conditioning components and mold caused by moisture. The details are as follows: Odor caused by dirt accumulation on air conditioning components: After years of use, dust can accumulate on the indoor filter and inside the copper fins of the air conditioner. When a certain amount of dust builds up, it produces an odor. When the air conditioner is turned on, this odor is dispersed into the air through the vents. Odor caused by mold from moisture: After the air conditioner operates in cooling or heating mode, moisture often remains inside the indoor unit. If the air conditioner is turned off immediately without a dry and anti-mold function, the moisture inside persists. Over time, this leads to mold growth, resulting in an odor in the car air conditioner.
