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.
