Using a vehicle’s air-conditioning system increases its fuel consumption more than any other auxiliary feature. An air-conditioning (a/c) system can increase fuel consumption by up to 20% because of the extra load on the engine.
Does running your air conditioner in your car burn more gas?
Can Using Car AC Be Fuel-Efficient? According to the EPA, using your car’s AC can be more efficient while driving at highway speeds than leaving the windows open. The main reason is open windows elevate aerodynamic drag, causing the engine to work harder and burn more fuel.
Does air conditioning in a car use up gas?
Yes, your car’s air condition system requires gas to operate. The air conditioner’s energy is supplied by the alternator, which is powered by the engine. As you know, fuel is necessary to power the engine.
Does AC or heat use more gas in car?
Air conditioning system is worse on fuel economy than the heating system because it requires more power to run. It is important to know that using the defroster in winter actually uses both the heating and the air conditioning at the same time!”
Does driving without AC Save gas?
In short, yes, but not really enough to matter, according David Bennett, manager of repair systems for the American Automobile Association (AAA). “The AC system, when operating, does add a slight load to the engine, which could slightly increase gas usage,” he says.
How much extra fuel does AC use?
Despite many believing this is a common misconception, air con does in fact increase your fuel consumption. Research has found that by using your air conditioning to control the climate of your vehicle, you can actually increase your fuel consumption by around 8-10%.

What uses more gas windows or AC?
“The rule of thumb is to keep the windows down while on city streets, then resort to air conditioning when you hit the highway,” says Slate writer Brendan Koerner. “Every car has a speed at which rolled-down windows cause so much drag as to decrease fuel economy more than a switched-on AC.
