How Often Should I Get My Car’s Air Conditioning Checked?

May 23, 2022

The air conditioning system in our car helps us all through the summer and offers a good alternative to open windows. But have you noticed that sometimes the air conditioning doesn’t work like it should and it suddenly takes ages until the car is reasonably cool? This is exactly why you may need an air conditioning check and service. This article will explain what you need to do in detail. 

So, how often should a car air conditioner be serviced? Generally, the air conditioning in a car should be serviced every two years. The cost of servicing the air conditioner in the car ranges from €80–€250 Euros. Since the air conditioner loses about 8–15% of its refrigerant per year, maintenance is required to regain maximum performance. If at any point you notice that your car is no longer getting really cool, you should take it to the workshop for an air conditioning check, as there could also be a leak in the cooling circuit.

In the rest of this article, we will give you more useful tips and also explain why your air conditioning sometimes smells bad. So be sure to read until the end!

How is the Air Conditioning in a Car Maintained? 

The process of air conditioning maintenance in a car is as follows: First, the functioning of the system’s parts is tested. These include, for example, the refrigerant compressor, the evaporator, and the condenser. In addition, hoses and seals are checked to see whether they are leaking and causing the refrigerant to escape. If any parts are broken or no longer fully functional, they are cleaned, repaired, or replaced by the technicians. You should keep in mind that maintenance of the air conditioning system should only be carried out by trained specialists, otherwise considerable damage can occur.

Incidentally, the entire air conditioning system is cleaned with a special disinfectant. As a result, fungi, bacteria, and other microorganisms are eliminated and your air conditioning system no longer stinks. In addition, it will have more power again.

Why Does the Air Conditioner Stink?

Everyone has experienced this at some point: you get into your car in summer, turn on the air conditioning and it starts to stink terribly. But why does this happen, and what can you do about it? Could it be time for an air conditioning check?

The air conditioner usually smells bad because fungi, bacteria, and other microorganisms can settle in the system and give off unpleasant odors over time. Since condensation forms through the evaporator, the multiplication of such microorganisms is only further promoted. 

To stop your air conditioning from smelling, it’s good practice to turn it off before you park your car. This helps to eliminate any remaining condensation and thus counteracts the formation of fungi. Also, you should know that frequent use of the air conditioner can lead to it smelling more. So try to drive with the windows open whenever possible to counteract this.

Having said that, to properly get rid of the bad smell, you may need an air conditioning check as well as to clean your air conditioner. You can find out how this works and how much it can cost in the next paragraph.

How Much Does an Air Conditioner Cleaning Cost?

Cleaning the air conditioning costs between €20–€50. The price varies from workshop to workshop. Basically, the air conditioning is completely disinfected here, which means that fungal accumulations or bacteria are eliminated and the stench goes away. 

Incidentally, the entire air conditioning system is cleaned with a special disinfectant. As a result, fungi, bacteria, and other microorganisms are completely eliminated and your air conditioning system will no longer have odors. In addition, it will have more power again. 

We strongly advise against cleaning your air conditioner yourself, as this is where things can go wrong. Also, simply going in with a vacuum cleaner will not help to eliminate the stench and get more cooling performance again. The bacteria usually collect in the air filter, which would have to be removed from the air conditioning system and replaced. That sounds simple, but it’s more complicated than you think. The air conditioning really needs to be thoroughly cleaned, preferably by trained technicians and with the right disinfectant, and the ability to perform an air conditioning check.

Conclusion

The air conditioning in a car should be cleaned every two years to ensure that it works optimally and is still leakproof everywhere. This also helps to ensure that bad smells are eliminated. The cost of maintenance is between €80–€250. 

You should also make sure that you don’t use the air conditioning too often to avoid it starting to stink. Furthermore, you should try to avoid trying to clean it yourself, as it often leads to damage to the air conditioning system if you do not have the necessary knowledge.
