It’s best to leave the cleaning of the car air conditioning system to a specialist in the workshop of your choice – just like the professional maintenance of the house air conditioning system. He will then replace the pollen and activated carbon filters, fill the coolant and check the evaporator.

Of course, you can also give a hand if your air conditioning system stinks – provided you have a knack for car repairs. But especially with such sensitive systems as the air conditioning system, many mistakes can happen without appropriate training.

That’s why cleaning in a workshop is more advisable. The costs are moderate and always cheaper than repairing broken parts, which is necessary because something went wrong when you did it yourself.

If the air conditioning in your car stinks, but you need the car urgently, then you probably can’t wait to get an appointment at the garage. Then you need a quick emergency service.

It is also available in the form of disinfectant sprays and cleaning foam. However, these measures only provide short-term relief and do not always eliminate the cause of the problem.

Sprays may mask the bad odors for a short time, but they often have little effect against the bacteria and fungi that cause the stench. Nevertheless, sprays and foams can at least combat the smell for the time if you find it difficult to breathe in your car.

The commercially available disinfectant sprays, especially for car air conditioning systems, are a good first measure. The application is straightforward:

  1. Start your car.
  2. Turn on the air conditioning system and select recirculation mode – no fresh air supply from outside.
  3. Make sure that all windows are closed.
  4. Place the spray can in the footwell of your car and press the spray button.
  5. Important: Leave the car and close the driver’s door.
  6. The can will now empty itself into the interior. The spray is getting absorbed by the air conditioning system and develops its disinfecting effect in the system.
  7. After approx. 15 to 20 minutes, the process should be completed. Now the car must be thoroughly aired – it is best to open all doors.

Cleaning the air conditioning system with a special cleaning foam is a little more complicated, but also more thorough. If you are a skilled craftsman and don’t mind a bit extra work, manual cleaning of the system is an excellent remedy against fungal infestation and bad odors. You will need the following items from a specialist shop or D.I.Y. store:

  • Effective cleaning foam
  • Large bucket/tub for the foam
  • Cleaning gun
  • Spray probe with ball jet nozzle

With the help of these utensils, you apply the cleansing foam directly to the evaporator and the ventilation ducts. It then acts against existing bacteria and prevents their re-growth. Alternatively, cleaning foam is also available in stores, which is getting supplied with a hose for application. As the cleaning systems all work slightly differently, it is best to seek advice from a specialist store.

It can happen that when the air conditioner is getting switched on after a long period of non-use, it suddenly starts to stink, and an unpleasant odor spreads inside the car.

The otherwise comfortable passenger compartment stinks. It is no reason to panic. It is usually caused by blind passengers who have settled on the air conditioning system’s heat exchanger in the form of bacteria, germs, and microorganisms.

If the air conditioning system stinks, the problem is unpleasant but can be eliminated quickly and easily by cleaning the heat exchanger.

When the car’s air conditioning system is getting switched off at the end of a journey, residual moisture can accumulate on the heat exchanger.

If germs and fungal spores from the ambient air then reach the heat exchanger during distant journeys, together with the residual moisture, a nutrient medium is getting created.

The microscopic guests can multiply unhindered. In the worst case, a kind of carpet is getting formed. As a result, the entire car will stink. This process is getting promoted by infrequent or irregular use of the air conditioning system.

In such cases, the air conditioning system stinks can only be getting remedied with a professional air conditioning system cleaning.

If such a situation occurs, motorists should not wait too long to have the heat exchanger professionally cleaned by a specialist workshop, if only because of the possible health risks.

The professional cleaning of the stinking air conditioning system should always be carried out by experts in a workshop who know what they are doing.

The background to this is that cleaning the air conditioning system can require extensive assembly work inside the car.

Furthermore, depending on the method, special equipment is also required. Therefore, if the air conditioning in the vehicle stinks, it is advisable to visit a cleaning workshop.

Professional air conditioning cleaning involves spraying special cleaning fluid onto the evaporator via the ventilation ducts, an assembly hatch, or a specially drilled hole.

It dissolves, destroys, and rinses away germs, bacteria, and fungi. The air conditioning system is thus getting disinfected.

At the same time, the evaporator receives a kind of protective film that makes it more difficult for pests to re-colonize. It is getting recommended to replace the pollen filter when cleaning the air conditioning system.

When the air conditioning is getting switched on, the air in the car is pleasantly fresh and clean again.

Cleaning the air conditioning system should take about 30 minutes to a maximum of one hour, depending on the vehicle.

However, a precise arrangement with the garage is necessary because cleaning and flushing the stinking air conditioning system is often only one component of a larger maintenance package.

Drivers can treat the air conditioning of their car one way or another. However, it is quite possible to prevent an air conditioning system from stinking and possibly being harmful to health.

First of all, it’s essential to observe the maintenance and inspection intervals specified by the vehicle manufacturer.

Within the framework of these intervals, all components of the air conditioning system like compressor, condenser, evaporator, and expansion valve are professionally getting checked, cleaned if necessary, and the pollen filter is getting replaced.

It ensures the function of the system as well as operation without disturbing fragrances.

It is helpful in the fight against bad smells to switch off the air conditioning shortly before the end of the journey. In this way, the remaining residual moisture on the evaporator can still be getting removed by the car’s ventilation system.

The air conditioning is then completely dry when the vehicle is parked. Then the causes of unpleasant smells cannot settle at all.

Regardless of the car’s service dates, we recommend having the air conditioning system cleaned every spring.

At that time, all traces of winter can be getting removed, and there will be no stinking surprises due to foul odors from the air conditioning system on your holiday trip.
