Dust, pollen, and other pollutants can accumulate in the vents over time, leading to poor air quality inside the car and potentially causing respiratory issues, such as asthma flare-ups. Use a soft-bristled brush or a microfibre cloth to clean the vents’ surfaces, and consider using an all-purpose cleaner for a thorough wipe-down.

If you notice a musty odour or reduced airflow, it might be wise to clean the internal ducts. You may need an air compressor with a long nozzle, a vacuum cleaner, and a dedicated vent and duct cleaner for this task. Additionally, regularly inspecting and replacing the cabin air filter will ensure that your AC system works efficiently and that the air you breathe inside your car remains clean.

Best Practices for Efficient AC Usage

To maximise the efficiency of your car’s AC system, consider adopting the following best practices:

  1. Start the AC While Driving: Engage the AC system once you start driving rather than when the car is stationary. This reduces the load on the engine and helps the AC system cool down the car more quickly.
  2. Use Recirculation Mode: This mode recirculates the already cooled air inside the car, making the system work less hard to maintain the desired temperature, which helps conserve energy.
  3. Adjust Temperature and Fan Settings: Set the temperature to the lowest setting and regulate the cabin temperature using the fan speed. This method reduces the workload on the AC system and improves fuel efficiency.
  4. Park in the Shade: Whenever possible, park your car in shaded areas to prevent the cabin from overheating. This helps the AC system cool down your car more efficiently once you start driving.
  5. Avoid Max AC Mode: Use the regular settings instead of the max AC mode, as the latter can overwork the system and consume more fuel.

By following these tips, you can maintain your vehicle’s AC system’s efficiency, ensuring it operates optimally between professional services.
