Does Using Air Conditioning While Parked in Summer Consume Fuel?

[DeclanLynn]

Air conditioning consumes approximately 20% of the engine's power, leading to fuel consumption when used while parked in summer. Below are relevant details about using air conditioning while parked: 1. Fuel consumption when parked with air conditioning: Currently, using air conditioning does not cause harm; it merely consumes more fuel. However, turning off the engine with the air conditioning still on can cause certain damage to the engine. 2. Reasons why turning off the engine with air conditioning is bad: If the air conditioning is not turned off when the engine is shut down, although the air conditioning stops working, it will default to the last used state the next time the car is started. This means the air conditioning will work simultaneously with the engine, adding its load to the engine. Excessive load on the engine can create a burden, and over time, this will inevitably reduce the engine's lifespan.
