Should the AC be turned on for cold air conditioning?

Car air conditioning AC activates the air conditioning compressor. To cool the air, press the AC button, which starts the compressor to refrigerate the hot and stuffy air in summer. The maintenance methods for car air conditioning are as follows: 1. Comprehensive inspection of the air conditioning: When using the air conditioning for the first time in summer, check the air conditioning system first. For example, check the refrigerant and whether the air filter is too dirty or if there are foreign objects in the radiator through the liquid storage tank. 2. Pay attention to the cleaning of the air conditioning: The air filter should be replaced regularly because there is a lot of sand and dust in spring, and willow catkins flying around, 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 air volume: The air conditioning will suck in a lot of dust during use. Regularly turning on high air volume 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 fluid should also be used for sterilization, cleaning, and odor removal.
When you turn on the cold air conditioning, you usually have to press the AC button because the AC activates the compressor, which is the key to cooling. After driving for so many years, I've noticed that many people mistakenly believe that simply adjusting the temperature will make it cooler. But without the AC, the air is just blown out without being cold, and the car remains uncomfortably warm. Remember to check your car's manual, as different models may have varying details. For example, some automatic air conditioning systems automatically activate the AC when you press the AUTO button, making it convenient and hassle-free. Also, pay attention to the fan speed setting—too high can be uncomfortable. In summer, it's recommended to start with a high fan speed to cool down quickly and then adjust it lower. During regular maintenance, have a technician inspect the air conditioning system. For instance, if the filter is clogged, the cooling effect will be poor, and timely maintenance can prevent mid-journey breakdowns. In short, turning on the cold air without the AC is a waste of effort, so it's better to operate it properly.
