Don’t turn on the air conditioner before getting in your car

Car AC will work much better when you are actually driving, the faster the engine spins, the faster the A/C compressor runs, allowing for a more efficient cooling system. Don’t waste time and fuel by turning on the air conditioner first to cool the car before driving. If the inside of the car is really hot, turn on the fan when you start driving and only open the rear windows for 10 to 20 seconds. This will force all the hot air out of the cabin. Don’t open the front windows, as that will only cause the hot air to move towards the front of the cabin, while the hot air in the rear will remain stagnant and the cabin will remain hot. 

Note: Do not turn on the air conditioner at the same time as starting your vehicle. Because if you just get into the car and turn on the air conditioner, it will cause the car to be started at low revs already under a large load, and the battery will be easy to damage.

Set AC to the coldest setting

This is an easy way you can apply. When the air conditioner is on, set the MAX or REC mode to the highest level to cool the car quickly. After feeling cool enough, start to switch to NORM or OUTSIDE, or FRESH mode, and lower the blower level. At this time, the airflow will recirculate inside your car and give you much relief. Don’t switch to the coldest setting when you just start the car.

Make sure the filter is clean

Please check the air filter, and be sure that it is clean. Dirty cabin filters will prevent optimal airflow. In newer cars, these filters are relatively easy to check; If you see a lot of dirt build-up on it, it means it’s time to change the filter. You can save money if you can replace the filter yourself in many modern cars. Of course, if that doesn’t work, you need to go to a car dealership.

Paste in the car insulation film

Limit direct sunlight to the interior compartment and it will reduce the heat inside your car. 

Turn on/off the air conditioner properly

Before starting the car, you need to turn on the exhaust fan to open the window to blow the hot air out. Then, when it has been blown out, you close the window and turn on the air conditioner.

This helps the vehicle to dissipate heat faster, and at the same time, pushes the carcinogenic toxins generated by the reaction of the plastic being heated at high temperature to the outside environment. Even when the car has rolled, it can be combined with opening the window for a faster effect.

In fact, many drivers often think that turning on the strongest blower in combination with the air conditioner will help cool the fastest.
