Should You Use Recirculation or Fresh Air Mode for Car AC in Summer?

[McAngelina]

If the driving duration is not particularly long and the distance is not very far, using the recirculation mode is relatively better. However, for long-distance trips, it's advisable to alternate between recirculation and fresh air modes. Here are some tips for using car AC effectively: 1. Ventilate before turning on AC: After the car has been exposed to prolonged sunlight, first open all four doors and the sunroof to allow air circulation for 3 minutes. This quickly lowers the interior temperature, making the AC cooling more effective when turned on. 2. Use recirculation mode wisely: Recirculation blocks outside hot air, creating a closed space inside the vehicle where air rapidly circulates under AC effect for quick cooling. Once the interior temperature drops, it's recommended to switch to fresh air mode every 30 minutes to purify cabin air, then return to recirculation after 5 minutes. 3. Turn off AC timely: Shut off the AC 5 minutes before parking, which both protects the engine and saves fuel.
