Air conditioning is no different from other vehicle components and also needs constant cleaning and maintenance. The durability of the equipment, the functioning of the car and the health of the driver and passengers depend directly on the care related to this item. For this reason, the cleaning of automotive air conditioning is essential.

In addition to the thermal comfort it provides, the use of air conditioning increases the safety of vehicle occupants and ensures that individuals inhale less air pollutants. However, to enjoy these benefits, it is necessary to perform maintenance and cleaning of the automotive air conditioner frequently. Learn how to do it.

Importance of Automotive Air Conditioning Cleaning

Automotive air conditioning cleaning can prevent unpleasant odors, accumulation of dirt and the spread of harmful germs. Respiratory diseases and allergic crises are some of the reactions that pollution and dirt present in the device can cause. In addition, the lack of cleaning damages the air conditioning system, which increases fuel costs, as the device becomes less efficient.

See why it is important to clean an automotive air conditioner:

  • Eliminates harmful germs to health;
  • Increases the useful life of the equipment;
  • Reduces corrosion and possible clogging;
  • Prevents leaks;
  • Reduces fuel expenses;
  • Ensures reaching the desired temperature, humidity and ventilation.

How to Clean Automotive Air Conditioning

Maintenance and cleaning of automotive air conditioners must be carried out in accordance with the specifications in the manufacturer's manual. Generally, it is recommended to carry them out every 30 thousand km traveled or 6 months. However, in some cases, maintenance may be required before this period. The air conditioning system must be checked whenever it shows signs such as a bad smell, a drop in performance or difficulty in air circulation. Follow the step by step below to carry out the cleaning of automotive air conditioner:

1st Step

The first step in automotive air conditioning cleaning is to remove moisture from the air ducts. To do this, turn on hot air to dry the tubing. Then get out of the car and leave the doors and windows closed for about five minutes. This process will remove moisture and lessen the likelihood of germs growing in the air ducts.

2nd Step

To perform the second step of automotive air conditioning cleaning, refer to the manufacturer's manual to find out where the air filter is located. It is usually on the dashboard, but the location varies by car model. Once you find it, please disassemble it carefully to avoid any damage that could interfere with the rear assembly or appearance of your car.

When looking for the filter, keep in mind that its color is white. If you notice that it is grayish in color and covered with dust, you will need to change it. To clean the filter, use a vacuum cleaner and a cloth.

3rd Step

The third step of automotive air conditioning cleaning relies on an ozonizer. This device works through the production of ozone and is responsible for decontaminating environments and surfaces in a microbiological way, without leaving chemical residues. In addition, this appliance has characteristic odors that can help in completing the cleaning.

The ozonizer must be applied with the elongator close to the air ducts. Be careful with the application of this product: any leakage can stain the panel, the multimedia system and even the seats.

Remember that the proper functioning of the car air conditioner depends on its correct use. Periodically turn on the hot air to dry the ducts and clean the air filters. In addition, the device must be started with the engine at low rpm and only after starting the vehicle.
