The temperatures are rising and the car is uncomfortably hot. Now only helps Air conditioning. As soon as you turn it on, you can feel the first cool breeze on your hot skin. However, that's not all. Suddenly spreads in the car unpleasant smell out. And you may be wondering: Where does the terrible smell suddenly come from?? This is not only uncomfortable for you, but also for the passengers. At least now it's time for one Disinfection. In addition to the body and the interior, you also need to regularly maintain the air conditioning. Here's what you're talking about Maintenance and cleaning need to know - also what the Air conditioning service costs.

Once the air conditioner smells smelly, it's time to sanitize it. After all, there is a reason why the loyal companion gives off an unpleasant smell through the summer. Mold, bacteria and microorganisms: You will feel like you are in paradise in a warm and humid environment. Both of these encourage them to spread on the evaporator and in the blower box. "back
The fact that the air conditioning needs to be looked after is making itself felt not always noticeable by the smell. Sometimes it just cools Do NOT spread pesto on this layer! as requested. Another sign of an appointment with the air conditioning service. Because the reason for the decreasing cooling function is that refrigerant. The system can lose around 15 percent of refrigerant every year. Only one thing can help: To top up the refrigerant regularly. Experts advise that you should have your air conditioning serviced every two years. Because if the coolant escapes, it pollutes the environment. Regular maintenance thus fulfills two important points: You save the environment and keeps you from high follow-up costs from unnoticed damage. "back
This is due to the temperature in the interior. As soon as it rises, the driver's concentration decreases strong. This increases the risk of an accident. That makes the air conditioning much more than a pure comfort function in summer - it does you active contribution for road safety. "back
What the air conditioning service costs you depends largely on the refrigerant used. For older models that rely on the R134a refrigerant set, the service costs between 40 and 120 Euro. However, this means is now Verboten. That is why new cars have only been allowed since the beginning of 2017 R1234y use as refrigerant. This results in higher costs because the product itself is more expensive than its predecessor. Between 100 and 200 Euro is the cost of the service, whereby the actual price depends on the required quantity and the hourly wage of the workshop. Repairing the air conditioner can reduce the cost increase additionally. "back
The air conditioning service checks the most important components: Expansion valve, Capacitor, Refrigerant compressor and vaporizer. Additionally need seals and Hoses to be controlled. They can dry out or age and as a result leaky become. Manufacturers therefore recommend one annual check. It is best to have this done in a specialist workshop. Because with incorrect maintenance you can Damage arise in the air conditioning system, which results in high follow-up costs. In the specialist workshop, on the other hand, trained specialists take care of the service and use a special one A / C service unit. Inform yourself before inspectionwhether the air conditioning is checked - this is not always the case. In most cases, however, you can also book the service.
If the cooling capacity decreases, a specialist must investigate (for example by adding contrast media) whether the system is leaking coolant. However, it works too without leak part of the remedy (it is a Gas) lost over time. For the driver, this means that the air conditioning system cools less. At the same time, expensive consequential damage becomes more likely.
There is a reason for this: the coolant is with oil enriched. This lubricates the compressor and protects seals from to dry out. The refrigerant therefore not only helps to cool the interior. If the workshop has to install a new compressor, the costs for it are around 800 to 1.500 Euro. "back
- Maintenance as well as functional and visual inspection
- Replacement of the refrigerant
- Add oil (for the compressor)
- Repair of the system (only if necessary)
To disinfect the system, Ozone used. This professional treatment removes bacteria and fungi. These can have accumulated on the evaporator, but also in the shafts and air ducts. Treatment with ozone costs around 50 Euros.
Also important: The Filters for the interior change regularly. This contributes to clean air in the interior and a ready-to-use air conditioning system. In addition, pollen does not stand a chance. How it works, you can read that here. "back
Who his air conditioning cleans itself, prevents unpleasant odors caused by bacteria and fungi. Special cleaning sprays and foams help disinfect the shafts, hoses and the evaporator. These funds cost between 10 and 15 euros per bottle. However, cleaning the system on your own replaces the professional air conditioning service can not be .
Cleaning foam for disinfection: Use a longer hose to spray the foam from the can directly into the vaporizer. The foam has to take effect for around half an hour, then start the engine, open the ventilation nozzles and turn the air conditioning on fully. This distributes the active ingredient. This variant is particularly active because it fights bacteria and fungi where they have settled: on the vaporizer.
Spray for disinfection: You use the spray with the engine running in the interior of the vehicle. The windows remain closed and the circulating air fan runs at the highest temperature and level. Then place the spray in the footwell, i.e. in the intake area of the air conditioning system, and activate it at the push of a button. It takes around 15 minutes for the spray mist to escape completely. One can is sufficient, the complete one Air conditioning and ventilation system to disinfect. Meanwhile, you can do not stay in the car. Once the disinfection is complete, you have to go inside ventilate thoroughly.
Also important: The cabin filter. You should do this in the course of disinfection change. Usually it is hidden in the engine compartment, behind the paneling of the bulkhead. That makes the exchange a little more complex. Even so, the exchange is possible on your own. A new Activated carbon cabin filter will cost you between 8 and 35 Euro. But the activated carbon filter is worth the price - unlike the pollen filter, it filters 92 percent of the toxic nitrogen dioxide from the air in the interior. "back
Basically, all air conditioning systems work the same: they contain one gaseous coolantthat is first sucked in by the compressor and then compressed becomes. This creates pressure that heats the gas. It is then cooled in the heat exchanger, where it changes to a liquid state. If there is water in the coolant, it is then cleaned using a dryer filtered out.
The next stop on the coolant is the expansion valve. From here it is metered into the evaporator. When it passes into the evaporator it will be again gaseousas it is no longer under pressure. In order for it to be able to change its state, however, it needs warmth. This heat is provided by the air that flows into the evaporator.
That ensures that the air strongly cooled is as soon as it passes the vaporizer. The cold air is passed into the interior using the ventilation nozzles. The compressor then sucks in the coolant again: the cycle starts all over again. "back
Air conditioners are in manuelle and automatic Differentiated models. If you have to operate the air conditioning manually, the temperature range that you have set will be used for cooling. On the other hand, if your car has a Automatic climate control is installed, the system regulates automatically. Sensors ensure that the desired temperature is maintained - even if the outside conditions change. It is particularly comfortable Multi-zone air conditioning: Here you can separated regulate, namely for the driver, the front passenger and possibly the rear area. Some models even vary their performance depending on the position of the sun, depending on the sensors installed. "back
Since a belt on the engine drives the air conditioning compressor, a consumption. The workload for the engine increases - so that too fuel consumption. According to ADAC, however, manual air conditioning systems consume more fuel than the automatic air conditioning. Because the automatic air conditioning varies the cooling capacity independently after the desired temperature has been set.
In addition to the type of compressor also affect the Operating conditions and the Power the additional consumption. The additional consumption varies between motorway journeys with 0,3 to 1,5 liters per 100 kilometers and in city traffic with 1,5 to 5,0 liters per 100 kilometers.
Additional costs arise from the Coolant replacement, the wear and tear of the Compressor shaft in the human body and facts about the Workshop costs. However, it doesn't help the air conditioner permanently switch off. If the air conditioning is not used in the long term, it happens damage to the system. Because without working, the air conditioning compressor is still belt-driven. That means for the compressor shaft too little lubrication and a permanent one Loss of refrigerant.
If the system then has to be sealed and refilled, the costs are high. Therefore, it should also be used in winter do not stay permanently switched off. Better: Set the temperature a little higher than the outside temperature. In this way, the compressor runs without additional consumption. "back
- Allow existing heat to dissipate through doors and open windows - only then switch on the air conditioning. Because: Pre-cooled indoor air can be cooled down more easily with less energy.
- Doors, windows and sunroof if possible closed hold or open as short as possible.
- The pollen filter is in recirculation mode less polluted. This reduces the cleaning and replacement cycle.
- The temperature should be a maximum of 5 degrees Celsius under the outside temperature.
- To prevent residual moisture in the evaporator: the system five to 10 minutes before the end of the journey turn off. This also counteracts the formation of germs. "back
