How much power does a car AC use?

around 4 horsepowerIn a modern automobile, the A/C system will use around 4 horsepower (3 kW) of the engine’s power, thus increasing fuel consumption of the vehicle.

Why does my car accelerate slower with the AC on?

What is happening is, basically, the air conditioner system needs extra power to run and that power is coming from your engine. With less power to work with, it means your engine isn’t able to put everything it has into accelerating – thus you often have a slower or sluggish acceleration.

Is idling with AC on bad?
