As temperatures soar and the sun blazes overhead, driving without a properly working AC can turn into a nightmare. When the temperature outside crosses 40 degrees, a car cabin can feel like a hot oven if the AC isn’t maintained well. Many people take their car’s air conditioner for granted, only to regret it when it stops cooling during peak summer.
To avoid such situations, it’s important to take care of your car’s AC system before the heat wave hits. Some easy and affordable tips can make sure that your drives remain cool and comfortable. Most of these things do not take much time or money, but they make a big difference in the long run.
Let’s understand how you can keep your car’s AC running like new.
Always Keep the Cabin Air Filter Clean
One of the simplest ways to maintain your car AC is to take care of the cabin air filter. This filter helps remove dust and dirt from the air before it enters the cabin. But over time, the filter gets blocked. When that happens, the airflow weakens, and the cooling drops. Sometimes, a bad smell may also come from the vents.
It’s best to check or change the air filter before summer begins. You can ask a mechanic to replace it, or if you like DIY work, it’s usually an easy job that takes just a few minutes. A clean filter ensures that air flows freely and cooling is better.
Go for Regular AC Servicing Once Every Year
Even if you don’t use the AC often, it still needs servicing at least once a year. Many parts inside the AC system – like the compressor, condenser, belts, and pipes – wear down or get blocked with dust. Also, the refrigerant gas can leak or reduce over time.
Servicing includes checking the gas level, looking for leaks, and cleaning the cooling coil. This improves performance and increases the life of the AC system. Make sure to visit a trusted service centre before the summer season begins.
Don’t Switch on AC Immediately After Starting the Car
A very common mistake people make is turning on the AC as soon as they start the car. But when the car is hot from inside, especially after standing in the sun, turning on the AC immediately puts extra load on the system.
Instead, first open the windows for a minute to let the hot air out. Start the car and let the engine run for 30-60 seconds. Then slowly switch on the AC. This reduces pressure on the compressor and helps cool the cabin faster and more efficiently.
Avoid Parking in Direct Sunlight
If you leave your car parked under strong sunlight for hours, the cabin becomes very hot. When you enter the car, it may take 10 to 15 minutes for the AC to bring the temperature down. This also increases fuel usage, as the compressor has to work harder.
To avoid this, always try to park your car in the shade. If a tree or covered area isn’t available, use sunshades or reflective window covers. These protect the dashboard and keep the temperature lower by several degrees.
Use the AC Regularly, Even in Winter
Many people think they should only use the AC in summer. But like any other machine, your car’s AC system also needs to run from time to time to stay in good condition. When you don’t run the AC for many months, the gas inside the system can get blocked, and seals can dry up or leak.
So, even in winter or rainy season, switch on the AC for at least 10-15 minutes once a week. This keeps the parts moving and reduces the chance of damage due to moisture or dryness.
Use Recirculation Mode for Faster Cooling
Most car AC systems come with a recirculation option. This allows the AC to cool the air already inside the car rather than pulling hot air from outside. When you use this mode, the cabin cools faster and the AC doesn’t have to work very hard.
Use the fresh air mode only when you need outside air, like in the mornings or evenings. For normal driving in the heat, recirculation mode is more efficient and helps maintain a cooler temperature for a longer time.
Don’t Overload Your Car’s Electrical System
If you use too many electronic devices like phone chargers, music systems, and additional lights while running the AC, the load on your car’s electrical system increases. This affects the performance of the AC and can even cause damage to the compressor.
Try to keep the extra load minimum, especially when you’re running the AC on full blast. Also, keep the cooling setting moderate once the cabin has cooled down, instead of running it at maximum the entire time.
Ensure the Cooling Coil and Vents Are Clean
The cooling coil or evaporator coil inside the AC system gets dirty over time. When it is blocked with dirt or fungus, it reduces airflow and causes a bad smell. Similarly, the AC vents may collect dust and particles that stop proper airflow.
During servicing, make sure to ask the mechanic to clean the cooling coil. You can also use a brush or vacuum cleaner to remove dust from the AC vents yourself. This ensures fresh air and better cooling.
Maintain the Correct Gas Pressure
Many people ignore the refrigerant gas level, thinking it’s not important. But low gas pressure means less cooling. On the other hand, overfilling the gas can also damage the system. That’s why it’s important to have the right balance.
Only trained professionals should check and refill the gas. During yearly servicing, they use a pressure gauge to see if the gas is low and refill only the required amount. Avoid going to roadside mechanics who may overfill the gas and cause damage.
Don’t Ignore Unusual Sounds or Smells
If you hear strange noises when the AC is on, or if you smell something odd, don’t ignore it. These can be signs of a faulty compressor, a gas leak, or mold in the vents. The earlier you check it, the less damage it will cause.
Ask your service centre to inspect the AC system immediately if you notice any changes in cooling, sound, or smell. Timely action helps avoid bigger repairs and keeps your car in top shape during summer.
Final Words on Keeping Your AC Ready for Summer
Summer driving is only fun when your car cabin feels cool and fresh. By following these simple and regular maintenance tips, you can enjoy every journey no matter how hot the day is. A little care goes a long way in keeping your AC working like new, year after year.
