Should the AC Button Be Pressed When Using Car Air Conditioning?
2 Answers
To use the air conditioning for cooling, it is necessary to press the AC button. Otherwise, the air conditioning system will only blow air at normal temperature because the AC button controls the compressor, which is the main component of the cooling system. Relevant information about car air conditioning is as follows: 1. How to use the A/C button: When the weather is hot and you need to cool down, press the AC button, adjust the temperature control knob to the blue section, then turn on the fan switch. The indicator light will illuminate, and the car air conditioning compressor will start working, blowing cold air from the vents. 2. How car air conditioning works: When the air conditioning is turned on, the blower in the system starts working, so air is blown out. However, the cooling system is not activated yet because the air conditioning compressor has not started working.
When it comes to turning on the car's air conditioning, I've learned from over a decade of driving experience: you must press the AC button. That button controls the compressor, which is responsible for cooling. If you only turn on the fan without pressing AC, the air coming out will be at room temperature or warm—it won’t cool at all, especially during scorching summer days, which can be unbearable. However, using the AC does increase fuel consumption slightly since the compressor has to work. But I’ve found that using it wisely can save some money—for example, starting with recirculation mode to cool down quickly, then switching to fresh air mode to ventilate and avoid stuffiness. Regularly checking the cabin air filter has also become a good habit of mine to ensure clean airflow. In short, trying to get cold air without pressing the AC button is just a waste of effort.
