Spring is the peak season for bacteria to grow, and the long-term operation of the automobile air-conditioning system leads to the accumulation of dust, and the mixed product with the air-conditioning water during cooling has also become a breeding ground for mold and bacteria. Usually when you turn on the air conditioner, you can smell a foul odor. In fact, the dust and dirt contained in the air entering the air conditioning system from the cooling fan will adhere to the air conditioning equipment.
So how to judge whether the air conditioning system needs to be cleaned? Generally considered from the following aspects:
1. The air conditioner has just turned on, and the blown air will smell like mildew and smoke when it has not cooled down.
2. When cooling or heating, the air blown from the seal is not fresh, accompanied by sour or other strange smells.
3. Because the evaporation box has not been cleaned for a long time, there is too much dirt, the cooling effect is reduced, and the fuel consumption is increased.
4. People in the car feel discomfort in the nasal cavity, trachea, and lungs, or are accompanied by coughing and chest tightness.
5. The vehicle has been used for more than one year, but the air conditioning system has not been cleaned and maintained.
Warm reminder: Air conditioning cleaning is very important for car maintenance in spring. If any of the above conditions are found, please clean the air conditioning system or replace the air conditioning filter in time.
