“Does using air conditioning in a car use more gas?”, is often asked by many people who either don't know about the working principle of the air conditioner in the cars or might have been misguided by some one.

You will often hear people suggesting you to use air conditioners in your car only when it is inevitable since, the gas or fuel efficiency reduces reasonably. That's true, using air conditioners burns some of the fuel from your tank but, it doesn't use enough of the gas. Before you come to any conclusion, get yourself acquainted with the mechanism of automobiles.

The cooling or the annealing equipment in cars vary in their design and models. Now, each of the them may differ in types but, basically the design and the concept are similar. They possess some mechanical units for the function of the automobile air conditioners that are directly attached to the engine. The extra work by the engine increases its load and so it draws more fuel in it.

Let's see how it happens. There is a compressor, commonly called the heart of the AC, attached to a belt driven by pump that is affixed to the engine. It's main  function is to compress and transfer the refrigerant gas. The belt rotates with the help of the engine and pressurizes the engine with more work. The engine runs on gas or other fuel, so it draws an extra amount of it. But, this amount is not as high as you think it to be.

You can also perform certain tasks to reduce the consumption of gas. Operate the thermostat after the interior is cooled, switch off the AC till again the temperature rises. In this manner, you save the fuel that it draws continuously while the AC is on. While in speed, give some space for ventilation. It helps in reducing fuel draw.
