10 Key Points to Improve Your Car’s AC Performance

Date: June 02, 2023

Car AC repair and services can be quite expensive but the good news is that it doesn’t have to be like that. Regular car maintenance can save you money. There are multiple factors which affect your car AC’s cooling power such as where you park your car or how well the parts have been maintained. You can take various steps to increase the efficiency of your car’s air conditioning & decrease the likelihood of a system failure.

1. Start The AC While Driving

Many drivers tend to start their AC before driving. However, doing so is a waste of both time and fuel. Your car’s air conditioning runs considerably more effectively while you’re driving because the compressor can run more quickly with the rotation of the engine’s crankshaft.

2. Window Shades

Since the glass in modern cars is good at blocking UV and the majority of infrared light, it offers little protection against visible light as well. As it passes through the glass, it transforms into infrared light, which then becomes trapped inside and heats up the car. Installing window shades is an extremely affordable way to limit the amount of heat buildup. 

3. Inspect the AC Filter

One of the main reasons why the air conditioning system in your car breaks down frequently is because of worn-out, unclean air filters. Old air filters force your car’s air conditioning system to work harder to push air through, which increases fuel consumption and reduces cooling performance.

4. Park in a shade

This is the most effective way to keep your car cool during summer. If the sun heats up your car, you will have to wait until it cools before getting in or starting the engine. By parking your car in a shade, you won’t have to be concerned about the sun heating up your car.

5. Inspect the Refrigerant


Regular use of the car’s air conditioning system might cause leaks that gradually reduce the amount of refrigerant in the system. Any refrigerant shortage in the air conditioning system can cause it to operate less effectively, especially in hot weather. To make sure that it is operating at its best and that there are no leaks in the system, consider getting it checked every six to twelve months.

6. Keep the AC Condenser Clean


The AC condenser is responsible for re-cooling the AC’s refrigerant by expelling the extra heat. However, dirt and debris can accumulate and obstruct the airflow, which drastically reduces the cooling capacity. To ensure that it performs at its best, make sure to have the AC condenser checked and cleaned on a regular basis from Fasttrack.

7. Switch the AC to Recirculation Mode

Sometimes, it is more efficient to turn your car air conditioner into recirculation mode than letting it cool the air from outside, especially when the outside air is above 50 degree Celsius.

8. Install an AC Curtain

If you’re the only passenger in a big car like an SUV or minivan, using the air conditioning to cool the empty seats can be a waste of energy. The best solution is an AC curtain, which can be utilized to cool the interior. A curtain can also speed up the cooling process and ease the workload on your air conditioner.

9. Ventilate Your Car

It is good for the vehicle to be ventilated before turning on the air conditioner. You should open all the windows and let the AC run in the car.

10. Have Your Car Serviced

Make sure to have your car professionally inspected and serviced on a regular basis to keep the air conditioning system operating optimally.  Since demand tends to increase in the summer, it is preferable to schedule the vehicle maintenance earlier so that you can benefit from lower prices and shorter wait times.

No matter how hot the temperature outside, you can ensure that your car’s interior will stay cool by following these tips. Additionally, over time, you will save money by using less fuel and spending less on your car AC service, repairs or part replacements.
