Tips For Using Car AC In Hot Weather More Efficiently

Using car AC in hot weather could be a tricky business because the auto air conditioning system gets a workout during the summer season. When the temperature rises so high that it seems to melt away even the asphalt on the road, you just want to turn the AC at a high speed, hoping to beat the heat. Most people don’t know how the system works, so they use it the incorrect way and burn more fuel than required.

Using Car AC In Hot Weather: Tips To Maximize The Performance

It’s a sunny summer afternoon and you just want to get home after your office. Well, get into the car and you will feel like being roasted inside an oven! It takes a few minutes for the AC to kick in and work in full swing. However, you don’t need to sweat anymore as these tips will help to cool the vehicle faster. Let’s check some best ways of using car AC in hot weather.

1. Pump out the hot air

Nobody likes to sit inside an oven, even if it’s for just a couple of minutes. So, your first step is to cool off the interior (or get the super-hot air inside the vehicle out). Before getting into the car, roll down the rear windows and successively open and close the driver’s door for several times. It will force out some hot air within seconds.

2. Pump out more while driving

The AC works much better while you are driving because is compressor runs faster with the rotation of the engine. Switching the AC on before driving will just be a waste of time and fuel. Keep the passenger seat windows open for half a minute to pump the hot air out of the cabin. Don’t make the mistake of opening up the front windows because it will clear up the front side only while the rear cabin is still hot.

It will be quicker if your automobile has a sunroof. While driving, keep it open for a minute and all the hot air will rise and get out through the hole.

3. Turn on the AC at low speed

You already know that the temperature inside a vehicle tends to be higher than the outside. Set the AC at the lowest temperature so that it draws air from outside the car and cools it down. On the flip side, turning it to the ‘Max’ will force the machine to take air from the passenger’s cabin, which is hotter than the outside air. So, the AC needs to work harder if you set it to the top speed at the beginning.

4. Change the dirty filter

Using car AC in hot weather most efficiently does not only need tuning up the system but also checking on a few components. You won’t get the optimal airflow if the cabin’s air filter is dirty. Check it regularly to see if it’s clear or collecting dirt. You will need to change it if it becomes grimy and greasy. It’s relatively easier to reach and change in newer cars, but you have to take the help of a mechanic in the case of an older model.

5. Use the recirculation mode

When you start the AC, set it to “recirculation” mode. This prevents hot air from outside from being drawn into the cabin, allowing the system to cool the air more quickly. Once the interior temperature is comfortable, you can switch to the “fresh air” mode to introduce outside air.

6. Park strategically

Whenever possible, park your car in shaded areas or use sunshades to block direct sunlight. This helps prevent excessive heat buildup inside the car, reducing the time and energy required to cool it down.

7. Set the temperature correctly

Set the AC temperature to a comfortable level rather than the lowest setting. Cooling the air excessively can strain the AC system and waste fuel. Aim for a temperature that keeps you comfortable without having to wear heavy clothing.

8. Maintain your AC system

Regularly maintain your car’s AC system by cleaning or replacing the cabin air filter as recommended by the manufacturer. A clogged filter can reduce airflow and efficiency.
