Should You Turn on the Car AC Immediately After Getting in the Car?

When the car is first started, the engine is not in an optimal state. Turning on the AC at this time will increase the engine's load. Here are some precautions for using the car AC: 1. Pay attention to the shutdown sequence: Do not turn off the engine before turning off the AC, as this can also harm the engine. The next time the vehicle is started, the engine will have to start with the AC's load, which can cause damage due to the high load. 2. Turn the AC on and off appropriately: During driving, it's inevitable to encounter long periods of traffic jams or waiting. If the AC is not turned off, the engine will remain in idle operation for a long time, leading to incomplete combustion of gasoline and the production of high concentrations of carbon monoxide. If the surrounding air circulation is poor, the carbon monoxide emitted by the engine can enter the car and cause poisoning. 3. Direct the air vents upward: Directing the cold air upward cools the car faster in summer, while directing the warm air downward heats the car faster in winter. The principle is simple—hot air is lighter and rises. This method is very helpful in saving fuel.
