Motorists should think twice before switching off their air conditioning this winter. As temperatures continue to drop, many drivers are beginning to stop using their air conditioning systems, believing that air-con is not needed during the colder months. However, car maintenance experts at Fixter warn that this common winter habit could lead to costly repairs, musty odours, and even fines of up to £1,000.

### Air Conditioning Isn’t Just for Summer Cooling

Air conditioning works as a dehumidifier, preventing mould, odours, and health risks—but only if used regularly. Switching it off in winter may seem like a money-saver, but the opposite is true. When unused, moisture builds up, bacteria thrive, and repairs become expensive.

A misted windscreen is more than just a nuisance; it could land you with a £1,000 fine and three penalty points. Using your cooling system is the quickest way to clear condensation and ensure you stay on the right side of the law.

### Six Recommended Ways to Keep Your Air Conditioning Running All Year Round

**1. Run Your A/C Regularly, Even on Cooler Settings**
Use your air conditioning for 10 to 15 minutes once a week, occasionally on a cooler setting. This keeps the seals lubricated, prevents mould growth, and stops the compressor from seizing. A small habit like this can save you from costly long-term repairs.

**2. Demist Your Windscreen Fast and Stay Legal**
The quickest and safest way to clear fog or frost is by combining warm air with your A/C. The system reduces humidity while the heat speeds up defogging. Direct airflow at the glass, avoid recirculation mode, and remember that driving with an unclear windscreen could cost you up to £1,000 in fines.

**3. Don’t Skip Your Winter Service**
Even if you’re not blasting cold air, your A/C is still working behind the scenes. Regular servicing keeps the system efficient, stops bacteria build-up, and reduces the risk of breakdowns when you need it most.

**4. Check Your Cabin Filter and Airflow**
A clogged pollen or cabin filter restricts airflow, slowing demisting and making your A/C work harder. If your vents feel weak, it could also signal low refrigerant levels. Both are quick fixes if caught early but can become expensive if ignored.

**5. Don’t Ignore Unpleasant Smells**
Musty odours when you switch on your A/C are usually caused by mould or bacteria. Aside from being unpleasant, they affect cabin air quality and your health. A thorough clean or filter replacement usually resolves this issue.

**6. Clear Vents Before You Drive**
Snow or ice blocking your car’s external vents can stop your A/C from circulating air properly, forcing the fan to overwork. Always brush them clear before setting off to ensure optimal performance.
