Under normal circumstances, the cleaning of automobile air conditioners mainly includes air filters, air conditioning pipes and evaporators. The cleaning of air filters and air conditioning pipes is relatively simple, and the owner can do it himself, while the cleaning of evaporators involves the overall disassembly of air conditioners. It is best to go to the automobile repair shop to find a master.

1, replace the air conditioning filter.

In general, the service life of an original air conditioner filter is one year or 30,000 kilometers. Clean the air conditioning filter: find the location of the air conditioning filter. Because of the different positions of the filter screen, some air filters are placed under the windshield of the car, and some are placed in the glove box of the co-pilot seat. Most models are disassembled in different ways, but the general steps are the same and it is not difficult.

Because the air filter is very cheap, if it is too dirty after being used for a while, throw it away! If the air filter is not dirty, the owner can use a hair dryer to blow the air conditioner filter clean from the inside out. At the same time, the arrow must be installed when installing, otherwise it will not work and will blow dust into the car.

Step 2 clean the pipeline

Cleaning air-conditioning pipes requires the purchase of air-conditioning cleaning agents; Shake the air conditioner cleaning agent evenly before formal cleaning, put the hose on the package, and adjust the air conditioner to the maximum circulating air volume, but don't turn on the air conditioner compressor (turn off the A/C button). Aim the swaying cleaning agent nozzle at the position of the air-conditioning filter element, and the suction inside will suck the cleaning agent, thus cleaning the air-conditioning pipeline. It is especially important to note that the hose of cleaning agent should not be too close to the blower to prevent it from being inhaled. After spraying the cleaning agent, the owner can let the air conditioning system run in the external circulation mode for 10 minutes, which must be done while the car is driving, otherwise the battery will be insufficiently charged and will be easily discharged. After cleaning the evaporator and air duct, the cleaning agent bubbles on the surface and flows out of the car along the drain.

3. Clean the evaporation box

Cleaning the air-conditioning evaporator requires disassembling the air-conditioning pipeline and evaporator, which is complicated and requires the use of professional tools. For safety reasons, it is recommended to go to the 4S shop for cleaning.

So for the health of you and your family, you must clean, sterilize and care the car air conditioner!
