Should You Turn on AC and Recirculation When Using Car Air Conditioning for Cooling?

[McOlivia]

When using car air conditioning for cooling, it is essential to turn on the A/C switch. Here are some related additional details: 1. The reason for turning on AC and recirculation when using car air conditioning for cooling: If you turn on the cooling without activating AC and recirculation, only the blower in the car air conditioning system will be working, and the air coming out of the vents will be at normal temperature. The A/C switch in the car is the air conditioning control switch, which essentially controls the compressor. By turning the A/C switch on or off, you can control the operation of the car's air conditioning cooling system. 2. Turning on the A/C switch in winter: In extremely cold northern regions where outdoor temperatures can be near or below freezing, even if you turn on the A/C switch, the car's air conditioning cooling system may not operate. However, one benefit of turning on the A/C switch in winter is that it helps dehumidify the air, preventing the car's windshield from fogging up and obstructing the driver's view. Additionally, practical tests have shown that turning on the A/C switch while using the heater does not affect the interior temperature of the car.
