Yes for sure, simply because the A/C unit is run by the engine of the car and the more work the engine is required to do demands more gas. Th A/C unit has a small compressor which compresses the coolant gas to a liquid, this liquid then passes thru a pressure regulating valve whereby the liquid now under low pressure reverts back to a gas, it is through this stage you get the cooling effect. The air from you car's fan blows across the radiator of the A/C and thus the air is cooled. The load on the car's engine comes from running the A/C compressor, it does this by a belt driven from the engines crankshaft. It has been estimated it reduces your miles per gallon by approx 2 to 3 miles when using the A/C. When using the A/C unit be sure you are using the internal air switch not the external air, it will cool much faster.

AC vs. Windows Down
Adam and Jamie tackle not so much a myth as what they call an "urban puzzle". The debate arises because both methods of cooling influence a car's fuel efficiency—air conditioning requires a lot of power to run, but at the same time, open windows create drag.
Revisited in MythBusters Revisited, Season 3, episode 38
Myth statement Status Notes
Running a car with air conditioning on is more fuel efficient than running with the windows down. Busted Tests were performed under varying conditions (55 mph versus 45 mph). Also, the 55 mph test was using a computer to estimate fuel efficiency based on air intake, not actual fuel consumption, and showed A/C was more efficient. The 45 mph test consisted of running the tank until it was empty, and showed open windows were more efficient. This experiment--or one like it--is sometimes cited by the Magliozzi Brothers on Car Talk when presented with this question.

Yep sure will but its so nice to be in the cool Just pay another $4 in fuel every time you fill up If your hot when your driving you will become more fatigued putting your self at risk and other road users around you

yes it will about 8-12% more but you can do things like letting off the gas pedal sooner and being lighter on when getting up to speed also just using it when you will be going a steady speed for a long time like on the highway. hope this helps

Sure will. More so on older vehicles than the newer ones though, because the A/C compressors are more efficient.

not much compaired to driving with open windows. and you paid 1000 dollars for the ac when you buy the car. For a buck or two a day why suffer. To really save take a train or bus. heck no!!

It will make the engine work harder than normal and therefore burn more fuel.

yeah i should think so :) about 7 - 13 % more but not too much of a biggy :)

yes, as much as 10% more.
