Your air conditioning system uses a refrigerant liquid to absorb heat, turning it into a gas. The system forces the refrigerant through a process of evaporating and condensing to constantly cool your vehicle.
The air conditioning system has three main parts: the compressor, the condenser and the evaporator. All three need to be working in harmony to keep the system flowing smoothly.
The most common cause of problems with an air conditioning system is that the refrigerant is running low. Problems with the compressor and the blower could also be the cause. Look out for these signs:
• Your windscreen and windows are slow to demist.
• It takes a long time for the air to cool
• Unusual noises coming from the air conditioning
• Cold air doesn’t circulate well
• There’s a bad smell coming from the air conditioning
If you have your Citroën serviced with an official Citroën dealer, our highly-trained technicians will check your passenger compartment filter at every scheduled service and replace it if necessary.
We can also check your air conditioning and apply a sanitising treatment to kill any nasty odour-creating bacteria that can build up in the system. Ideally you should have this done once a year.
Bacteria builds up naturally over time. It can cause bad smells and aggravate allergies. Coming in for regular maintenance with Citroën will help to keep the system fresh and clean.
You can also help to reduce the build-up of bacteria by running your air conditioning for around 10 minutes each week, during both summer and winter.
