When to Turn on the AC in a Car?
2 Answers
When the weather is hot and you need to turn on the air conditioning to cool down, you can turn on the AC. Here is some introduction about the AC switch: 1. Car air conditioning is divided into cold air conditioning and hot air conditioning. Hot air conditioning does not require turning on the AC, you only need to turn on the blower to use the engine's heat for heating; while cold air conditioning requires turning on the AC switch to make the air conditioning compressor work to produce cold air. 2. In addition, mid-to-high-end car models will have an additional AUTO button, which means automatic air conditioning. When the AUTO button is turned on, the vehicle's computer will automatically identify whether to turn on warm air or cold air through temperature sensors.
I turn on the AC mainly during hot weather, like in summer when the sun is directly shining and the car feels like a steamer. At such times, turning on the AC quickly cools down the car, making it more comfortable. Especially in heavy traffic, not turning it on would leave me sweating profusely and prone to heatstroke. I usually press the AC button to start cooling as soon as I start the car, with the fan speed set a bit higher. I also pay attention to AC maintenance, such as cleaning the filter, to avoid poor cooling or unpleasant odors. For long trips or when traveling with kids, I definitely turn on the AC to keep the car cool, ensuring safety and preventing fatigue, setting the temperature around 25°C to avoid affecting fuel consumption.
