Should the AC be turned on when using air conditioning in summer?

In summer, the AC should be turned on when using air conditioning. The AC is an air conditioning device, and this button controls the activation and deactivation of the compressor. The car air conditioning can cool the air by relying on the operation of the compressor. In hot summer, when the AC button is turned on, the temperature control should be adjusted 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. The AC is the switch for the air conditioning compressor. The car air conditioning system includes not only the compressor but also components such as the condenser, evaporator, and expansion valve. However, the compressor is one of the main components of the refrigeration system, responsible for compressing and transporting refrigerant vapor.
In summer, you need to turn on the AC to get cooling, otherwise it's just blowing air without any effect. Having driven for over a decade, I always press the snowflake button in summer—only when the compressor kicks in can it cool and dehumidify. Without AC, the car interior becomes hot and stuffy; even rolling down windows wide open won't help and may even increase fuel consumption. Set the temperature around 25°C after activation for optimal comfort; with automatic climate control, hit AUTO and the system decides when to engage AC. Use recirculation mode for faster cooling and safer long-distance driving. Regular AC maintenance is crucial—low refrigerant or dirty filters impair performance, so an annual checkup is highly recommended.
Driving in summer without AC is unbearable. I usually press the snowflake button to turn on the cooling as soon as I get in the car. Without it, the AC just blows air and doesn't cool much, especially when stuck in traffic, making me sweat. The automatic AC is thoughtfully designed—pressing AUTO activates the AC for temperature control and intelligently adjusts the fan speed. Setting it to 23°C keeps me comfortably cool. Keeping windows open long-term consumes more fuel and is less safe, so using AC is more convenient. Avoid setting too large a temperature difference between inside and outside the car to prevent discomfort when getting out. Regularly clean the vents to prevent odors and maintain system efficiency.
