Air conditioning
If your Mercedes air conditioning isn't blowing cold, takes longer to cool down, or has a musty smell when switched on, it's time for a service. Benza Autos offers air conditioning regas, leak testing and repairs from £49.99 inc VAT, with honest pricing without the main dealer premium.
We check system pressures, test for leaks, and regas using the correct gas for your Mercedes — R134a Air Con Gas for older vehicles, or R1234yf Air Con Gas for modern vehicles (post-2017). We inspect components including the compressor and condenser, and if a repair is needed, we'll explain what's wrong and quote a fixed price before ordering parts.
Most manufacturers recommend an air conditioning service every two years. Regular maintenance keeps your cabin comfortable, prevents compressor damage, and catches small leaks before they become expensive repairs.
Part of our Mercedes-Benz specialist work in Birkenhead — all models welcome.
