Should the AC be turned on for cold air?

Automobile air conditioning AC activates the air conditioning compressor. To cool the air, you need to press the AC button. When the AC button is pressed, the air conditioning compressor starts working, cooling the hot and stuffy air in summer. The maintenance methods for automobile air conditioning are as follows: 1. Comprehensive inspection of the air conditioning system: When using the air conditioning for the first time in summer, first check the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty through the liquid storage tank, and whether there are foreign objects on the radiator. 2. Pay attention to the cleaning of the air conditioning: The air filter should be replaced regularly, because there is a lot of dust and willow catkins in spring, which will stick to the filter and easily breed bacteria, causing a musty smell in the air conditioning. In addition, the condenser should also be cleaned regularly, and the water tank should be removed for thorough cleaning. 3. Regularly turn on high fan speed: The air conditioning will suck in a lot of dust during use. Regularly turning on high fan speed can blow out the dust on the inner surface of the air conditioning ducts, which is a simple way to keep the air conditioning clean. In addition, special duct cleaning solutions should also be used for sterilization, cleaning, and odor removal.
Well, turning on the cold air is something worth mentioning, based on my years of driving experience. You need to press the AC button because AC is the core part of the air conditioning system, controlling the compressor to cool the air. If you don’t turn it on and only use the fan, the air blowing out won’t be cold—it’ll just be outside air or warm air, depending on your AC system settings. In the scorching summer, I always turn on the AC to cool down, especially during traffic jams when no cold air can be unbearable. Not using AC might save a bit of fuel, but it’s not worth it in extreme heat. Also, automatic AC is more convenient—just press AUTO and it adjusts the fan speed and AC status on its own. Remember to check the cabin air filter and refrigerant regularly to avoid reduced cooling efficiency. In short, if you want real coolness, turn on the AC—no need to hesitate.
To be honest, you must press the AC button when turning on the cold air, otherwise it's just a waste of effort. The AC controls the cooling unit, and only when activated can it produce cold air. Without turning it on, the fan merely blows regular air, which isn't cool at all. I usually pay close attention to fuel consumption when driving, and turning on the AC increases fuel usage. So, on cooler days, I turn off the AC and just use the fan for ventilation, which is both comfortable and economical. Sometimes, when there's an odd smell inside the car or the windows fog up, turning on the AC can also dehumidify and maintain clarity. For automatic models, simply setting the temperature is enough—it's straightforward and smart. I recommend starting with simple operations to avoid overburdening the system.
