According to the website howstuffworks, whether or not the air conditioner is on does not affect the car's engine. Because, with most cars today, when starting the engine, the ECU will automatically adjust to turn off all other support systems of the car, focusing all fuel and electricity on the engine. Users can notice this when turning on the power switch, the lights, radio... are still running, but when starting the engine, these systems will automatically turn off for a few seconds. The air conditioner is no exception.
But that does not mean that turning off the air conditioner before stopping the car is not advisable, on the contrary, it is highly recommended. A few minutes before the end of the journey, the driver should turn off the air conditioner to save gas, and at the same time help the body gradually get used to the outside temperature, avoiding heat shock.
In addition, turning off the air conditioner before stopping to run the fan will help dry the air vents, avoiding stagnant humid air that causes mold, a cause of unpleasant odors every time you enter the car.
In addition, to save fuel when using air conditioning, drivers should apply some methods such as opening the windows, turning off the air conditioning at low speed, when the outside air is clean, the temperature allows. Do not open the windows at high speeds of about 80 km/h or more because at this time the large air resistance consumes more fuel than using air conditioning.
In addition, to use air conditioning effectively and save fuel, especially in the summer, car owners should apply frosted glass, park in a shady place, do not set the air conditioning too low... and pay attention to regular maintenance.
