With scorching summer temperatures on the horizon, experts reveal a simple air conditioning adjustment in vehicles that could help drivers save up to 10% on fuel consumption.

How a Small Air Conditioning Adjustment Could Save You Big on Fuel


As temperatures across Europe and beyond soar in what is expected to be an exceptionally hot summer, many drivers are bracing for increased fuel consumption as air conditioners work overtime to keep vehicles cool.

But experts say a simple adjustment to your car’s air conditioning settings could significantly reduce fuel usage — and it all comes down to how your vehicle circulates air.

The Key is in Air Circulation Settings


Modern vehicle air conditioning systems offer two main options for airflow: drawing in fresh air from outside or recirculating the air already inside the cabin. According to automotive experts, the latter can lead to substantial fuel savings, especially during the summer heatwave.

When your car's air conditioning system pulls air from outside, it has to work considerably harder to cool that hot air, placing extra strain on both the air conditioning unit and the engine — which, in turn, burns more fuel.

However, by switching to the recirculation mode, your vehicle uses the cooler air already inside the cabin, gradually reducing the temperature with far less energy required. Not only does this improve the efficiency of the cooling system, but it also helps keep dust, pollution, and unpleasant odours from entering the vehicle.

Substantial Savings Over Time


It is estimated that using the air recirculation function effectively during hot weather can reduce fuel consumption by as much as 10% — a significant amount, particularly for those clocking up long distances or commuting daily.

While the recirculation mode is recommended for most situations during the summer months, experts suggest briefly switching to outside air intake during long journeys. This helps refresh the air quality inside the cabin without significantly impacting fuel efficiency.

Air Conditioning, Comfort and the Cost of Driving


With fuel prices remaining volatile and summer temperatures pushing air conditioning systems to their limits, small adjustments like this can help motorists reduce fuel bills without sacrificing comfort.

In addition to saving on fuel, using the recirculation function can also extend the lifespan of your vehicle’s air conditioning system by reducing the workload on its components.

As the mercury rises and drivers prepare for long journeys under the summer sun, this simple yet effective trick serves as a timely reminder that efficiency often lies in the details.

By making one quick adjustment to your vehicle’s air conditioning settings, you could keep cool, stay comfortable, and save money — all while reducing your carbon footprint.
