How to Make Car AC Cooler: 5 Simple Hacks

How to Make Car AC Cooler?

To make your car AC cooler, there are several steps you can follow.

First, replace the cabin air filter to improve air flow and prevent pollutants from entering the car.

Park your car in the shade to prevent heat buildup inside the vehicle.

Check the refrigerant levels using an A/C gauge and thermometer, and recharge if needed.

Gradually cool down the A/C system by not immediately switching to “max cool” upon starting the car.

To make the air conditioner feel colder, start by pulling air from outside the vehicle with the fan at maximum speed and the airflow set to “outside” mode.

Then, switch to “recirculate” airflow mode and set to “max cool.” If the AC is still not getting colder, there may be issues such as a leak or worn-out parts that need inspection and repair at an auto care center.

Key Points:

  • Replace cabin air filter for better air flow and to prevent pollutants
  • Park car in shade to prevent heat buildup
  • Check refrigerant levels with A/C gauge and recharge if necessary
  • Gradually cool down A/C system instead of immediately setting to “max cool”
  • Pull air from outside with fan at maximum speed and airflow set to “outside” mode
  • Switch to “recirculate” airflow mode and set to “max cool” to make AC feel colder

Did You Know?

1. Most car air conditioning units use a special refrigerant called R-134a, which is designed to be more eco-friendly and safer for the environment compared to its predecessor, R-12.

2. The AC compressor, which is responsible for circulating the refrigerant in the car’s cooling system, is often referred to as the “heart” of the AC system.

3. In some cars, the AC system can be set to automatically circulate fresh air from outside or recirculate the air already inside the vehicle. Recirculating the air inside can help improve cooling efficiency as it uses the already cooled air.

4. A car’s AC system does not produce cold air directly; rather, it removes heat and humidity from the existing air inside the vehicle to create a cooler sensation.

5. To improve your car’s AC cooling efficiency, park in shaded areas whenever possible, as direct exposure to sunlight can heat up the interior and make it more difficult for the AC system to cool the car effectively.

Parking In The Shade

One of the simplest yet effective ways to make your car’s air conditioning cooler is by parking your vehicle in the shade. When a car is parked under direct sunlight, it can experience significant heat buildup, causing the interior temperature to rise rapidly. Research shows that cars parked in direct sunlight can reach internal temperatures of up to 131-172°F when outside temperatures range from 80-100°F.

By parking in the shade, you can greatly reduce the heat buildup inside your car. Shade provides a natural barrier against direct sunlight, preventing the interior from becoming too hot. Finding a shaded spot or using covered parking areas can make a noticeable difference in keeping your car cooler, especially on scorching summer days.

In addition to parking in the shade, using a windshield sun shade is highly recommended. This is an effective way to protect the interior of your car from UV damage. Sun shades are designed to block the sun’s rays from directly entering the car, reducing the amount of heat and UV radiation that penetrates through the windscreen. By using a sun shade, you’ll not only keep the car cooler but also protect your dashboard and upholstery from fading and sun damage.

Checking Refrigerant Levels

Low refrigerant levels can lead to inadequate cooling in your car’s air conditioning system. It is essential to regularly check the refrigerant levels to ensure optimal performance and maximum cooling efficiency. Fortunately, checking refrigerant levels is a relatively simple task that you can do at home or at an auto parts store or auto care center.

To check the refrigerant levels at home, you will need an A/C gauge and a thermometer. First, connect the A/C gauge to the low-pressure port of your car’s A/C system. Next, turn on the engine and set the A/C to the maximum cooling level. The gauge will provide a reading of the refrigerant pressure. Compare the reading to the manufacturer’s specifications to determine if the refrigerant levels are within the recommended range. In addition, check the temperature of the air blowing from the vents using a thermometer. If the air is not as cold as it should be, it may indicate low refrigerant levels.

Gradual Cooling Down

When starting your car, it is not advisable to immediately switch to the “max cool” setting. Your car’s A/C system needs some time to cool down gradually before providing the maximum cooling effect. Jumping straight to the coldest setting may overwhelm the system and result in inefficient cooling.

To ensure proper cooling, follow these steps:

  1. Set the fan to the maximum speed and the airflow mode to “outside”. This will help force out some of the hot air trapped inside the car.
  2. Allow the air to circulate for a few moments before switching on the A/C.
  3. Once you turn on the A/C, switch the airflow mode to “recirculate”. This prevents hot air from outside entering the cabin and allows the A/C system to cool down faster.
  4. Finally, set the A/C temperature to the desired level, gradually lowering it until you reach the desired coolness.

By following this gradual cooling down process, you can optimize the performance of your car’s A/C system and enjoy the maximum cooling effect it provides.

Adjusting Air Flow Settings

To make your car’s air conditioner feel even colder, it’s important to adjust the air flow settings appropriately. Begin by pulling in air from outside the vehicle. To do this, set the fan to maximum speed and the airflow to the outside mode. This will draw in fresh air from outside, which is typically cooler than the air inside the car.

After a few moments of circulating outside air, switch the airflow mode to recirculate. This mode recirculates the already cooled air inside the car, preventing hot air from entering and ensuring that you achieve the desired level of coolness faster.

Once the airflow is adjusted to recirculate mode, set the A/C to max cool. This setting ensures the A/C system operates at its highest capacity, providing the maximum cooling effect possible. As the A/C system cools down the re-circulated air, you will start to experience much cooler air blowing from the vents, allowing you to enjoy a comfortable and refreshing drive.

Seeking Professional Inspection And Repairs

If your car’s A/C is still not getting cooler despite following the previously mentioned tips, there may be underlying issues that require professional attention. Problems such as refrigerant leaks or worn-out parts in the A/C system can significantly affect its performance and cooling effectiveness.

In such cases, it is advisable to seek professional inspection and repairs at an auto care center, like Firestone Complete Auto Care. Their expert technicians are trained to diagnose and resolve A/C system issues efficiently. They have the necessary tools, equipment, and expertise to identify leaks, repair or replace faulty components, and restore your car’s A/C system to optimal condition.
