Do You Need to Turn on AC When Using the Car Air Conditioner in Winter?

You don't need to turn on the AC when using the car air conditioner in winter. The suitable temperature for car air conditioning in winter is around 20 degrees Celsius. The method to turn on the heater is: 1. After starting the car, wait for the water temperature to rise to the normal level, then turn on the heater switch; 2. Adjust the air circulation mode to the internal circulation setting; 3. Set the air conditioning to the appropriate level and adjust the air direction. The functions of the car air conditioner are: 1. To regulate the temperature, humidity, airflow direction, and speed inside the car, and improve the air quality through the filter; 2. To provide a comfortable riding environment for passengers and reduce travel fatigue; 3. To create good working conditions for the driver and ensure safe driving.
In winter when using the air conditioning, you usually don't need to turn on the AC because the AC mainly activates the compressor for cooling. Turning it on will additionally increase engine load, raise fuel consumption by over 10%, and accelerate part wear. After years of driving, I've found that winter warmth comes from the engine's residual heat, which naturally warms up quickly, making AC unnecessary. However, during damp and cold weather when window fogging affects visibility, turning on the AC with warm air can quickly dehumidify, clearing fog within two to three minutes to ensure safety. Normally, I keep the AC button off and just adjust the temperature, saving fuel and hassle. Regularly cleaning the filter can also prevent fogging. Don't let the compressor work unnecessarily; warm air alone is enough for comfort.
