How to Use Car Air Conditioning in Summer?

Usage of car air conditioning in summer: 1. Turn on the external circulation of the air conditioning or open the windows for ventilation, then switch to internal circulation and AC after 1 to 3 minutes to start cooling; 2. Direct the air conditioning vents upwards. According to the physical principle that cold air sinks and hot air rises, directing the vents upwards cools the car faster; 3. Turn off the air conditioning before shutting down the engine. The key is to turn off the AC cooling function, as the air conditioning compressor is driven by the engine. This prevents the engine from starting under load the next time the car is started. Running the air conditioning while the car is idling puts more pressure on the engine and significantly increases fuel consumption. Some drivers also have the habit of sleeping in the car with the air conditioning on, which is very dangerous.
Driving in summer can be unbearably hot. My routine is to start the car, roll down all windows for a minute or two to let the hot air escape before closing them and turning on the AC. Setting the temperature around 24°C is most fuel-efficient, starting with high fan speed then gradually reducing it. Remember to use the fresh air mode to circulate outside air, preventing stuffiness or fogging inside. Turn off the AC five minutes before parking to utilize residual cooling for better energy efficiency. Also, clean the cabin air filter every six months to prevent dust buildup and musty odors. These habits, refined over years of experience, ensure comfort without wasting fuel while extending AC lifespan and saving maintenance costs. Perfect for keeping cool and safe during summer road trips.
