If you're lucky, on a hot day, you can run from the air conditioning at home or at work to the air conditioning in your car.

However, it can take a few minutes for a car to cool off. Some people roll down their windows, while other blast the AC, but Consumer Reports says there is a better way.

First, do not sit and cool the car. Get in, and get it moving.

Consumer Reports experts say the AC works much better when the car is moving. The faster the engine turns, the faster the AC compressor runs.

They say it is best to open all of the windows and crank up the air when you feel that it is cooling off. Close the front windows, but leave the back ones open for another 10 to 20 seconds. That will force the hot air out, experts said.

If you have people in the back, don't recirculate the air. Recirculating the air keeps everyone up front cool, but neglects the back.

If your car has automatic climate control, lowering the temperature does not make the car cool off faster. Most systems will do the fan and temperature adjusting automatically, experts said.
