Generally speaking, the automobile air conditioner smells when it is turned on, mostly because of the evaporation box. After the air enters the car, it will be cooled or heated through the evaporation box, and then the cold and warm air will be blown out through the air outlet. In the process of use, it is inevitable that bacteria, dust and even insect carcasses will enter the evaporation box. Over time, the air conditioner will smell when used.
Therefore, in this case, you should go to a professional automobile maintenance organization to clean the evaporation box of the car, so as to eliminate the odor.

Cleaning skills of automobile air conditioner
1, clean the car air conditioner with air conditioner cleaner:
(1) General automobile air conditioners have a pollen filter at the air inlet, which is used to prevent external dust from entering when the automobile air conditioner is externally circulated. When cleaning the air conditioner, remove the pollen filter, inject foam cleaning agent into the air conditioner from the air inlet, and close the air outlet of the air conditioner to prevent the foam cleaning agent from flowing out of the air outlet.
(2) Then, start the car, turn on the air conditioner, and let the foam cleaning agent circulate inside the air conditioning system. This step will last for several minutes to ensure that the foam cleaning agent circulates to all channels of the air conditioning system. About 5 minutes, turn off the air conditioner and turn off the car. It won't take long for the dust to flow out of the cabinet from the air conditioning piping system. This cleaning method is suitable for the time when the automobile air conditioner is not particularly dirty.
2. Remove and clean the car air conditioner:
Another cleaning method of air conditioner is disassembly and washing, which is much more troublesome than the first method. First, you have to take apart the dashboard and take out the evaporator of the air conditioner. An air conditioner evaporator that has not been cleaned for a long time must be covered with dust and needs to be carefully cleaned with a brush. Reinstall the air conditioner after washing, and then clean the air conditioner in the first way.
