What else can I help you with?
What consumes more gas driving with the windows down or driving with air conditioning?
theorically driving with the windows down will use more gas due to the disturbance to the car s aerodynamics
What consumes more fuel in a car Air conditioning or driving with the windows down?
On the side of air conditioning causing the car to use an unnecessary amount of fuel, this fact is true. Sort of. The truth is using the car's air conditioning does burn more gas, especially when driving in town. In this driving situation fuel consumption goes up by roughly 10%. A good rule of thumb to follow is when the car is moving at a rate of 40 mph or slower, driving with the windows down is definitely the better option for fuel efficiency. That means that for trips to the grocery store, post offices, and visiting ma and pa, drive with the windows down. On the other side of the debate, we have the air conditioning saves on gas due to eliminating air drag on the car from the open windows. Once again, this theory is correct as well, in certain conditions. When driving on the highway or at speeds greater than 45 mph, open windows increase air drag on the car to a point where fuel efficiency is lost by up to 10%. In cases where the vehicle is running at speeds closer to 55 mph, gas inefficiency reaches the 20% mark. Very simply put, both sides of the debate are correct depending on the kind of driving in question. When town driving, leave the windows open, when highway or higher speeds driving, the AC is definitely the way to go.

Does air conditioning increase fuel consumption?
I have been told that it does. I have one vehicle with air conditioning and when I turn on the air I can hear the motor lug just a little. The compressor that circulates the gas that creates the cooling must require some energy from the motor therefore taking some energy from what goes to the drive train. When the air is off, the compressor free spins and saps no energy from the motor. Since I am not an expert, this an opinion rather than a fact.I have seen quite a few studies, that confirmed that a car uses less fuel with the A/C on at highway speeds, as compared to the same vehicle traveling with the windows down and A/C off. The open windows create more drag than does the compressor and that decreases mpg. In city driving it definitely uses more fuel with the A/C on.Yes it will use a little more fuel in around town driving. But open highway driving; It takes the same amount of fuel due to drag withthe windows open aswith the A/C on. So either way the fuel mpg is the same on highway driving. The comfort in town and short trips, heck use the air if need be.
How many miles per gallon does air conditioning use on a ford focus?
About 4-5. If you are traveling at highway speeds you will get no less mileage with the A/C as you will with the windows down. So enjoy the ride, close the windows and turn on the A/C. In town it is totally different and you will get less with the A/C on.
When air conditioning should you open windows or doors?
no
Is it bad to have the air conditioning on while the windows are open?
Yes, it is not efficient to have the air conditioning on while the windows are open because it can waste energy and increase electricity costs.
When driving in summer heat what should be your first priority?
When driving in summer heat the first priority for the car is making sure the engine doesn't overheat. It is a good idea to use the windows and vents to cool both the driver and engine rather than the air conditioning.
Why do windows in a house with air conditioning sometimes have dew on it?
Because the windows are cooled by the air conditioning therefore the water vapor in the surrounding air condenses on them. Much like a glass containing a cold drink has dew on it.
Can you tell me how to properly ventilate a room with windows open and the air conditioning on?
To properly ventilate a room with windows open and the air conditioning on, you should open windows on opposite sides of the room to create cross ventilation. This allows fresh air to come in and stale air to go out. The air conditioning helps to maintain a comfortable temperature while the fresh air circulates.
Why the windows open while driving fast in a highway makes the engine to consume more energy Why?
Modern cars are practically all have a streamlined design to help them meet and minimize wind resistance ... rather like a boat 'cuts' through the water. The body design wants to minimize swirls of air that cause 'drag' on the body as it moves. If you have the windows open while driving, you cancel out these 'slick' design features. The wind is sucked in through the windows, swirls around and then is forced out by more air entering. That's drag. The breeze blowing in your face might feel good but, closing the windows and cranking up the air conditioning can feel just as good, and it puts less load on the engine and increases your gas mileage.
What is highway hyponosis and how can you fight it?
After driving for awhile. Your eyes start to stare out on the road and your mind will wander. Move your eyes from side to side. Look at the right berm the left berm. Look up get the big picture.
Is it better to run your air conditioning in your house with your windows open or closed?
Closed! If you leave the windows open all the cool air will go out the windows, and your house won't get cool.
