Do You Need to Press AC When Turning on the Air Conditioner in Winter?

[SanAdeline]

You do not need to press the AC button when turning on the air conditioner in winter. The AC button controls the car's air conditioning compressor, which is only necessary when cooling in the summer. Pressing the AC button activates the compressor to provide cooling. Warm air, on the other hand, utilizes the car's internal heat circulation principle and does not require the air conditioning compressor. The heating system uses the heat generated by the engine to warm the air. After the engine's cooling system dissipates heat, a fan directs this heat into the car's cabin to produce warm air. Even if the heating is not turned on, the heat generated by the engine's operation is expelled outside the car. Car heating is a form of waste heat recycling. Using the heating system in winter does not affect the car's performance or increase fuel consumption.
