How to judge whether the air conditioning system of your car needs to be cleaned?
1. When the air conditioner is just turned on, when the wind is not completely cooled or heated, it will smell a smell similar to mildew and smoke.
2. When cooling or heating, the air blown from the tuyere is not fresh, accompanied by sour smell or other strange smell.
3. The cooling effect decreases and the fuel consumption increases. Due to the evaporation box has not been cleaned for a long time, too much dirt, thus affecting cooling.
4. when people are in the car, they feel uncomfortable in the nasal cavity, trachea and lungs, or are accompanied by cough, chest tightness and so on.
5. The air conditioning system has not been cleaned and maintained for more than one year.
In the case of the above situation, 4S stores will advise car owners to clean air-conditioning pipes. The project is not only time-consuming but also certainly not cheap. In fact, cleaning the air-conditioning pipes in the car is not difficult, do-it-yourself DIY, half an hour can solve the problem. Today, we will clean the DIY with our own air conditioner and do a little health care for our car.
First learn the principle of car air conditioning, if not cleaned in time, a large number of bacteria and viruses will enter the respiratory tract with the wind, thus affecting the health of the people in the car.
The self-bought air conditioning cleaners, air conditioning fungicides and odor deodorants bought by yourself are said to achieve deep cleaning, quick deodorization and will not cause any side effects of corrosion or short circuit to the hardware of the air conditioning system in the car. Don’t talk too much nonsense, let’s get in the car and try.
Let’s start with a group photo of the air conditioning maintenance package.
It just so happens that the wiper water is gone, so make do with it. I really need it when driving, especially when it is rainy and dusty, so I often keep a bottle in the trunk.
Pour concentrated wiper essence and then pour filtered water ~ ~ now the water purifier is still quite common.
Make the first step of cleaning first. First of all, start the vehicle, let the vehicle idle, then open the window, turn off the AC switch when the air volume of the air conditioner reaches the maximum gear, and then remove the air conditioner filter element. The position of the air conditioner grid of each car is different. Most models will be in the armbox and only a small number of models will be in the engine compartment. Then connect the nozzle with air conditioning cleaning agent, shake it deep into the air inlet, gently press the nozzle in stages, wait for 2 minutes after each pressure for 10 seconds, and then wait for the second time until the end of use. The raw liquid used in this air conditioner cleaning agent is in the shape of foam, which is safe and environmentally friendly. After cleaning, continue idling for 10 minutes and then turn off the air conditioner and engine, you can see the turbid waste liquid coming out from the bottom of the vehicle.
It is true that it is very dirty inside, and it has been replaced for more than half a year in the last maintenance. Let’s get a new one this time.
Press the cleaning agent and pour it into the tuyere if there is foam.
Press for about 10 seconds to take a rest and wait for the fan to spin and absorb the foam into the pipe.
You can see the waste liquid flowing out under the chassis.
The air volume is very large, and you can see that the foam is fully circulating in the pipe, overflowing from each outlet.
Then go on to the second step of cleaning the package DIY, using germicidal deodorant. This is also very easy to use. After installing the nozzle, shake the bottle up and down, extend the nozzle to the air outlet of the air conditioner, and spray it several times one by one. At this time, the air conditioner in the car basically has no smell, and a fresh smell is coming.
A new air conditioner filter will be installed later.
After a ten-minute break, let’s take the third step of air conditioning maintenance, close the window and use a freshener, which is easier, just open it and put it on the water cup rack or on the co-driver’s floor mat. Close the door when the gas is emitted. Just open the door when the spray is over. At this time, the air conditioning cleaning process of the car is complete. In fact, air conditioning cleaning is not a complex process, do-it-yourself can save hundreds of yuan. Under normal circumstances, cleaning 2-3 times a year is the best.
It was done in about half an hour, and the car was really delicious at this time.
After the hot and humid summer, we enter the autumn to welcome the winter. Thoroughly cleaning the air conditioning system for a car can not only improve the refrigeration effect, save refrigeration costs, thus reduce fuel consumption, but also protect evaporators and compressors to prolong the service life of air conditioners, but also clean air and prevent air conditioning diseases. Why not?
