Why does car ac use gas

Does car AC use gas? Your AC draws power from the alternator, which in turn is powered by the engine. Fuel will be used to power this process. However, in some situations using your AC can actually be the most efficient. So, how does car AC use gas? All car air conditioning systems run on a high-pressure gas called refrigerant. Based on recommendations from the EPA, using your AC while driving at highway speeds is more fuel-efficient than leaving the windows down. While it can be refreshing to roll down the windows while cruising through Fenton, it also creates more drag.

When this happens, your engine has to work harder and burns more fuel to maintain higher speeds. So if you are looking to maximize your fuel economy, using your AC while on the highway will not be wasteful.
