Because it's attached to the engine and uses power when you turn it on. Even if it wasn't attached to the engine, anything in or on a car that takes power in some form will use fuel because ultimately it's the engine that supplies that power.

Does air-con in a car really use your fuel?

If you mean does the A/C cause the engine to use more fuel, the answer is yes and no. In city driving the A/C does indeed cause the engine to use more fuel. On the highway at speed, the engine uses about the same amount of fuel with the A/C on as with the A/C off and windows down. It also depends on the model year of the car. Older cars have A/C compressors that require more power to drive.
