How can I make my car AC cooler?

Confused about how to make your car’s AC colder? It’s a piece of cake! You just need to follow some steps and use your car’s ac in a proper and efficient manner. There are multiple factors on which your car AC’s cooling power depends. Starting right from the place you park your car to the level at which the components have been maintained, all of them affect your car AC’s cooling.

Without getting into the technical part, let us first have a look into the daily habits that can help you extract maximum from your car’s AC.


Park in a shade

This is the best method to keep your car cool in the summer days. If you park your car in the shade, you will never have to worry about the sun heating your car up while you are away! If the sunlight heats your car up, you will have to wait till it cools down before you get in or start driving. This will eventually waste your time and fuel! Parking in the shade gives you an added advantage with your car’s paint protection. The sunrays have bad long term effects on your car’s paint and you can avoid them all by simply parking your car in the shade.


Drop down the windows

In case you are not able to find a spot that’s in the shade, you can leave the windows open smidgen, enough to let fresh air circulate. This will help to reduce the greenhouse effect which would otherwise heat up your car. Alternatively, you can buy and use sunshades which will block the sunlight from entering into your car.


Ventilate the car

If all of the above wasn’t possible for you then this one will surely work. When you reach your car after it has been parked under the sun for long then before you start driving, you must properly ventilate your car’s cabin. The hot air that has built up while you were away, needs to be eliminated before you start driving again. If you skip this one, then you will surely struggle before you get comfortable in the cabin.

What is the fastest way to cool a hot car?

Ventilating the car can cool your car down effectively. Just roll down the driver’s side window and use the passenger side door to fan the hot air out. Alternatively, you can also roll down the rear windows and let the hot air escape. 


Pump out hot air 

A parked car on a hot day is nothing less than an oven. You won’t like to sit in an oven, obviously! So before you enter the car, make sure you ventilate it well before you enter the cabin. Roll down the windows and let the hot airflow. The hot air will automatically flow from your car’s cabin to the surroundings because the air inside the cabin is hotter than the air present outside.


Pump out more hot air

Start driving slowly and let the air flow. You can make the hot air escape by simply rolling the windows down and starting driving. Don’t just open the front windows as it won’t let the rear side of the cabin cool down. Open all the windows of your car and let the hot air flow. The hot air will escape and a nice airflow will be created. This will ultimately cool the cabin a bit. If your car has a sunroof, open that too and the hot air will escape easily.


Slow and steady wins the race

Turning the AC on at the minimum speed will help you get better cooling. You already know that the temperature inside the vehicle is higher than the outside temperature when you get into the car. If you set the blower to the maximum speed then the AC will force the machine to take air from the passenger’s cabin. This will make the AC work harder to cool the cabin. So remember, start at the minimum speed. Just to let you know, the automatic air conditioning systems that are equipped in the cars nowadays, start at low speeds only. So if you have a car with a manual air conditioner, control it in the same way as the automatic air conditioning system does.


Use the recirculation mode 

Once the AC starts blowing cool air, turn on the recirculation mode. This means that the AC system won’t pull the outside air and will use the air already present inside the cabin. This will help the system to cool the cabin down without putting in the extra effort.


Shut down properly

Once you have reached your location, make sure you switch the air conditioner off before you turn off the engine. You can let the fan run for a while. This will help it dry the evaporator and its surroundings.


Maximising the cooling from your car's AC requires a combination of proactive measures and efficient usage. By parking in the shade, ventilating the car, and pumping out hot air before driving, you can reduce the initial heat buildup inside the cabin. Opening all windows and using the minimum speed setting on the AC blower help create airflow and gradually cool down the interior. Additionally, utilising the recirculation mode and properly shutting down the AC after reaching your destination can further optimise cooling efficiency. By following these tips, you can enjoy a cooler and more comfortable driving experience during hot weather.


Maximising car AC cooling: park in shade, ventilate cabin, pump out hot air, open all windows, start at minimum speed, use recirculation mode, and shut down properly for efficient cooling.
