In order to ensure that the air conditioning system continues to work properly, you must ensure that you regularly maintain and examine the air conditioning system. Read here what to look out for to ensure that your air conditioning system continues to work optimally.
Why is maintenance so important?
- The refrigerant evaporates for several reasons;
- Hoses always keep leaking a little;
- Seals age and will therefore leak;
- Service connections may leak due to soiling and faulty operation;
- Components in the system become defective;
- Moisture can enter the system;
- Various pipes and components are vulnerable to, for example, stone chippings or other mechanical damage, which can also lead to leakage again.
How often should the air conditioning be checked?
It is recommended to have your air conditioning system checked annually. This is because the interior filter removes dust, pollen and dirt particles from the air before the air enters the cab clean and cooled. However, the evaporator also needs to be closely monitored. Bacteria, fungi and micro-organisms often nestle in it.
During a check the components are checked, the function and performance are tested and if necessary the interior filter is replaced and the evaporator disinfected. This can be compared to a 'small service'.
Keep in mind that you give the air conditioning system a 'big service' every two years. In the case of a large turn, the filter dryer is replaced, the refrigerant is refreshed and a leak test is carried out.

What tools do I need to find faults?
- Gas bottle;
- Equipment for measuring whether your air conditioning system is working properly;
KL093910 and/or KL093940. - Leak detection set UV; KL092032. With this set you can use UV light to find out where the leak is.
It is important that the radiators are clean.
Make sure you always use the air conditioning system or never use it. If you keep turning the air conditioning on and off, there is a good chance that condensation will get into the evaporator and it will eventually start to mould.
Protect yourself
Liquid refrigerant R134a evaporates at -26.3°C. At normal room temperature it evaporates extra quickly, causing everything that is in contact with the refrigerant at that time to freeze immediately. The right gloves and eye or face protection when handling refrigerant is therefore strongly recommended. Do you also work with a chemical rinsing agent? Then additional respiratory protection may be necessary. Do not forget to make sure that there are no open flames or smokers around.
Farmer's tip' to check whether your air conditioner is working
Check whether the discharge line at the pump is getting hot. You can feel it by hand. The other pipe should then remain cold. Make sure that the air conditioning is on when you check.
