Do you need to press the AC button when turning on the air conditioner in summer?

In summer, you need to press the AC button when turning on the air conditioner, as the AC button is the cooling switch for the car's air conditioning system. When the AC button is pressed, the engine drives the air conditioning compressor to work, which cools the hot air from outside, allowing cool air to blow out from the vents. The method for using the car's AC button is as follows: 1. First, turn on the fan and set the airflow to maximum, initially using the external circulation to draw out the hot air inside the car. 2. Then, turn on the AC for cooling, and after about two minutes, switch to internal circulation. 3. When turning on the AC button, adjust the temperature control to the blue position. For automatic air conditioning, you can set a temperature and then press the AUTO button, and the automatic air conditioning will adjust the interior temperature automatically.
As a seasoned driver with over a decade of experience, I always press the AC button in summer—it's the core of activating cooling. The AC button in the air conditioning system specifically activates the compressor, circulating refrigerant to cool the air. If you only turn on the fan without pressing the AC button, the air blown out is just hot outdoor air, causing the car temperature to rise rapidly on hot days, making it impossible to cool down. Maintenance is also crucial: regularly cleaning the AC filter prevents reduced airflow and moldy odors; older cars especially need refrigerant level checks to avoid diminished cooling performance. Press the AC button early in high temperatures and pair it with recirculation mode for faster cooling. Safe driving shouldn’t be overlooked—without proper cooling in hot weather, drivers risk fatigue and dehydration, which is highly dangerous.
I usually pay attention to fuel consumption and environmental protection when driving. In summer, whether to press the AC button depends on the situation. The AC button activates the compressor for cooling, but it consumes more fuel; if the weather is not too hot or the speed is high, you can open the windows for ventilation instead of pressing the AC button, saving fuel and being environmentally friendly. For example, when driving on the highway with high wind speed, natural wind can also cool down. However, on extremely hot days or in traffic jams, opening the windows is ineffective and lets in dust, so pressing the AC button for quick cooling is necessary. It's also important to check if the air conditioning pipes are aging, as poor sealing reduces cooling efficiency. Balancing comfort and environmental protection, choosing the appropriate air conditioning mode wisely is a smart approach.
