As summer temperatures rise, a properly functioning air conditioning (AC) system becomes essential for comfortable travel. AC is required not only to cool down the temperature but also to help in eliminating any bad odour.

If your car’s AC isn’t performing optimally, it’s time to take action.

In this blog, we will explore practical tips to help you improve your car’s AC performance and ensure a cool and enjoyable driving experience.

Let’s dive in!

Tips to Improve AC Performance

1) Regular Maintenance

Similar to any mechanical system, your car’s AC requires regular maintenance for optimal performance. Periodically inspect and clean the AC system’s components, including the condenser, compressor, and evaporator, to prevent debris buildup and ensure proper airflow. Seek professional assistance if you’re unsure about performing these tasks.

2) Clean or Replace Cabin Air Filter

The cabin air filter plays a vital role in maintaining clean and fresh air inside your car. Over time, it can get clogged with dust, pollen, and other pollutants, restricting airflow and reducing AC performance. Consult your car’s manual to locate the cabin air filter and clean or replace it at recommended intervals.

3) Check Refrigerant Levels

Inadequate refrigerant levels can lead to poor cooling performance. If your car’s AC isn’t cooling as effectively as it should, check the refrigerant levels. Ideally, consult a professional equipped with specialized tools to perform this task. They can also inspect the system for leaks and undertake necessary repairs.

4) Park Car Under the Shed

Parking your car in direct sunlight can turn it into an oven, making it difficult for the AC to cool the interior. Whenever possible, park in shaded areas or use windshield sunshades to minimize heat buildup. Consider tinting your windows as well, as it reduces the amount of heat entering the car.

5) Proper Ventilation

Ensure unobstructed airflow through the AC vents by keeping them clean and free from debris. Check for any objects, such as papers or leaves, blocking the vents. When using the AC, ensure the vents are fully open and direct the airflow towards you for maximum cooling efficiency.

6) Use Recirculation Mode

When driving in hot weather, switch your AC to recirculation mode. This setting recirculates the already-cooled air within the car, reducing the workload on the AC system and improving cooling performance. Remember to switch back to fresh air mode occasionally to prevent the air from becoming stale.

7) Drive with Windows Closed

While it may be tempting to lower the windows and enjoy the breeze, driving with windows open at high speeds creates a drag that reduces the efficiency of your car’s AC. To maximize cooling performance, keep the windows closed while the AC is in use.

8) Use Lower AC Settings

Running the AC at its highest cooling setting might seem like a quick solution, but it can strain the system unnecessarily. Instead, set the temperature to a comfortable level and adjust it gradually if needed. This approach helps maintain a consistent temperature and reduces stress on the AC components.

9) Switch the AC Off Before the Engine

Yes, you heard it right. Whenever you reach your destination then first switch off the AC before turning off the engine. When you turn the engine on again, it may create a little bit of stress on the engine or starter motor, if the AC is already ON.


A properly functioning car AC system is crucial for comfortable summer driving. By following these tips and giving your car’s AC the attention it deserves, you can enhance its performance and enjoy refreshingly cool air even on the hottest days.

Remember, regular service, cleanliness, and smart usage are key to unlocking the full potential of your car’s AC.

Have a cool and comfy driving experience!
