Firstly, you cannot run the AC without the engine running. To make the A/C work, it requires a compressor to act on the refrigerant, and the compressor runs off of the engine, not the battery. The air conditioner compressor and clutch are operated by the serpentine belt that also runs the other accessories of car.

Yes — like many of your car’s features, the air conditioning system uses gas. The air conditioner draws energy from the alternator, which is powered by the engine.

How long can car AC run battery?

Your car battery can give you an estimated 28 to 30 minutes of air conditioning while your car engine is off; this is true with a 40 amp-hour battery which is the industry standard. For longer AC use, choose a battery that has a large amp-hour rating. But we do not recommend using AC only through your car’s battery.
