How much fuel is consumed by idling with air conditioning on for one hour?

[GabrielAnn]

For general household vehicles, idling with the air conditioning on for one hour typically consumes about 1-2 liters of fuel, though this may vary depending on the vehicle model. Relevant details are as follows: 1. Influencing factors: The fuel consumption of idling with air conditioning on is related to many factors such as the vehicle's displacement, air conditioning power, external environment, and engine tuning. Instead of focusing solely on the economic cost of fuel consumption, more attention should be paid to the potential damage to the vehicle and the resulting increase in long-term maintenance costs. 2. Carbon deposits: When the engine runs at low RPMs in an idling state for extended periods, carbon deposits are more likely to form on the pistons and valves. Excessive carbon deposits can directly impact fuel economy and may also affect the engine's performance and even its lifespan.
