Do You Need to Turn on AC When Using Heater in Winter?

[StJourney]

For fuel-saving considerations, it is completely unnecessary to turn on the AC button when using the heater in winter. Here is some relevant information about the AC button: 1. Introduction: The AC is the switch for the compressor, simply put: it delivers cold air. A car's air conditioning system consists of not just the compressor, but also components like the condenser, evaporator, and expansion valve. However, the compressor is one of the most important parts of the refrigeration system, responsible for compressing and transporting refrigerant vapor. 2. Function: Turning on the AC switch is definitely required when using the car's cold air function. Otherwise, the air conditioning system is merely operating the blower, delivering air at normal temperature. On hot summer days, 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 system will automatically adjust the interior temperature.
