How often should it be serviced?
Run the system regularly, including in winter. The cabin filter is often replaced yearly or every 10,000–20,000 miles. Refrigerant recharge is not automatically required on a fixed date: reduced cooling should first prompt a performance and leak check.
Signs of an air-conditioning fault
Weak cooling, bad odours, noise when engaged, persistent misting or visible leaks need inspection. Recharging without finding a leak can hide the fault and release more refrigerant.
Recharge and diagnosis cost
A recharge commonly costs €70–€180 depending on refrigerant. Cleaning and a cabin filter add to the price. Condenser or compressor repairs can cost several hundred euros or more.
