Release trapped heat from your car
You should ventilate your car before turning on the AC. Sliding down the windows of the car before turning the ignition on helps to release the trapped heat. Doing this will bring down your car’s temperature which will help AC to cool faster.
Parking car away from direct sunlight boosts AC’s efficiency
Parking the car cool can help the AC to perform efficiently. Keeping your car away from direct sunlight or keeping it under the shade helps to avoid overheating and it also makes it easier for AC to cool better. If the AC is already super hot before you turn it on, it may take longer to cool the car.
Car AC condenser is responsible for re-cooling refrigerant by expelling the excess heat into the passing airflow. The path of the airflow can be clogged with dirt and debris resulting in reduced cooling efficiency. You should make sure that your car’s AC condenser is cleaned regularly.
After turning on the car AC for a while, you should enable the recirculation mode once you start getting cool air. The recirculation mode makes sure that the AC does not pull the outside air and use the air available in the car cabin. This mode helps the AC to cool the car quickly without much effort.
