Air-conditioning system maintenance



Read the following to find out more about the air-conditioning system in your car and about what it can and does do. Your air-conditioning can do a lot more than keep your car at a pleasant temperature in the summer.


Comfortable climate

Comfortable climate
When you switch on your air-conditioning, the air temperature in your vehicle is adjusted to the temperature you have set.
This is particularly beneficial in the summer. The sun may be lovely, but it does not make driving any easier, especially when heat builds up inside your car. Your air-conditioning system can ensure you have a comfortable and relaxed journey.

Clear view!

Clear view!

Did you know that the air-conditioning is responsible for keeping your windows clear in winter?

Windows fog up quickly when you get into your car and it is wet and cold outside and fogged-up windows significantly restrict your view. Fog is just humidity from the air that condenses on your windows. Humidity gets into your vehicle in clothing, shoes and coats.

But just turn a simple knob, and your air-conditioning can provide increased visibility and safety. It dries the air inside your car, which defogs the windows quickly.

Just switch on your air-conditioning and direct the air flow to your windscreen. Switch to air recirculation and set the blower and heater to maximum. You will then see the fog disappear from your windows.

But keep in mind that the automatic air-conditioning switches the system off automatically when the outside temperature falls below around +4 °C in some models from various manufacturers. Not all vehicles allow you to use recirculation mode when the air-conditioning is turned on and the air flow is directed onto the windscreen.


Clean air

Your air-conditioning does not just change the temperature of the air inside your vehicle. It also ensures the air is clean!

Because the air-conditioning system also includes the cabin filter—and this performs the most difficult work: It filters dust, dirt and pollen from the air, up to 300 m3 of external air per hour. Thus, pollutants no longer reach the vehicle cabin. At such an output, it is easy to understand why the cabin filter is saturated after around one year and has to be replaced.




The evaporator is part of your air-conditioning system. It is located below the dashboard in a dark, damp area. This is the ideal location for bacteria, fungi and micro-organisms. These pathogens can then get into your vehicle cabin via the ventilation system. This can trigger allergic reactions in some people, such as sneezing, coughing and watery eyes. The problem can only be solved by disinfecting the evaporator during regular maintenance.

More safety!

More safety!

Did you know that your air-conditioning system can also contribute to your safety? Though it may not seem that obvious at first. Air-conditioning keeps the vehicle cabin comfortable and prevents blistering heat. When heat builds up in the vehicle, your body tires out more quickly, which in turn has a negative impact on reaction times and concentration. The risk of an accident significantly increases. Even at a temperature of 27°C in the vehicle cabin, the number of accidents in built-up areas increases by 11%. At an interior temperature of 32°C, this figure increases by about 22%*! But you can keep a cool head if your air-conditioning system is working properly and your reaction time and level of concentration levels are not impaired.
