Myth 1: AC instantly  cools the car

Fact: Your AC needs time to circulate and bring down the temperature. Ventilating the cabin first helps speed this up.

Myth 2: Lower temperature offers better cooling

Fact: Setting the AC to extreme lows increases fuel use. Around 24°C is optimal for comfort and efficiency.

Myth 3: Opening window is better then AC for efficiency

Fact: Opening windows while driving actually increases the fuel consumption due to reduced aerodynamics.

Myth 4: You don’t need to service the AC

Fact: Regular maintenance improves cooling, prevents odour, and extends system life.

Myth 5: Recirculation mode is only for winters

Fact: It’s useful in summers too — it cools the cabin faster by reusing already cooled air.
