Should You Turn on AC When Using Car Air Conditioning in Summer?
2 Answers
In summer, you must turn on the AC switch to get cold air from the car's air conditioning system. Otherwise, the system will only operate the blower, delivering air at normal temperature. On hot summer days, when you press the AC button, you need to adjust the temperature control to the blue position. For automatic air conditioning, you can set a desired temperature and then press the AUTO button, which will automatically adjust the interior temperature. More details about AC are as follows: 1. The car air conditioning AC is the switch for the compressor, which delivers cold air. The car air conditioning system includes not only the compressor but also components like the condenser, evaporator, and expansion valve. The compressor is one of the most important parts of the refrigeration system, responsible for compressing and transporting refrigerant vapor. 2. First, turn on the blower and set the airflow to maximum. Run the external circulation for two minutes to draw out the hot air inside the car. Then, turn on the AC for cooling. After two minutes, switch to internal circulation, and the car will quickly cool down. Once the interior is cool, you can temporarily turn off the AC. When the temperature rises again, turn the AC back on. This method of using the air conditioning can help save fuel.
I've been driving for over twenty years, and in the summer, you absolutely must press the AC button. AC stands for the air conditioning compressor switch; only by turning it on can you cool the air. If you only turn on the fan without AC, you'll just get hot or room-temperature air, which won't lower the temperature at all. Especially after the car has been baking in the sun, it will only get more uncomfortable. Not using AC in high temperatures can lead to dehydration and fatigue, affecting driving safety and potentially causing accidents. My habit is to first open all the windows for two minutes to ventilate and expel the hot air, then close the windows and press AC to start the air conditioning, setting the fan speed high for quick cooling. Set the temperature to around 25 degrees—no need to go too low and waste gas. Remember to change the air conditioning filter annually to keep it clean. On long summer drives, it's impossible to get by without AC; cooling is a basic necessity, and safety comes first.
