Delhi heatwave alert: Is your car AC ready? 6 critical checks to know

Delhi is once again dealing with intense summer conditions, with the India Meteorological Department issuing heatwave alerts as temperatures cross 42°C. With the mercury expected to rise further, driving without a properly working AC can quickly become tiring and uncomfortable. In this kind of heat, your car’s air conditioning is not just about comfort. It helps you stay alert and focused on the road.

Quick AC checks ahead of peak summer

One of the first things you can check is how quickly the AC cools the cabin. If it takes longer than usual or the air does not feel cold enough, it could be a sign of low refrigerant or a weak compressor. You may also notice this more in traffic, where cooling tends to drop.

You can also look at the cabin air filter. In Delhi’s dusty conditions, it gets clogged easily. A dirty filter blocks airflow and reduces cooling. Replacing it is simple and can improve performance instantly.


Another thing you should not ignore is smell. If you notice a damp or musty odour, it could mean there is fungal buildup inside the vents. This affects both cooling and the air you breathe inside the car.

It is also worth checking the cooling fan and condenser. If these are not working properly or are covered in dirt, the AC will struggle, especially in slow traffic.

Airflow strength is another easy indicator. If the blower feels weak even at higher speeds, there could be an issue with the motor or blocked vents.

Lastly, pay attention to sounds. If you hear unusual noises when the AC is on, it could point to compressor-related issues. It is better to get these checked early.
