BOISE – According to estimates by the U.S. Department of Energy, running your air conditioner on long road trips can lower fuel economy by as much as 25 percent.  AAA is sharing tips to help cool down your car more efficiently.

  • Find a shady spot to park.
  • When you start your car, roll down all the windows, and use fresh-air mode (non-circulating) to help flush the warm air from inside the vehicle.
  • Once you hit highway speeds, roll up the windows, then switch to circulating mode.
  • Check and replace the cabin air filter every 15,000 miles or as needed.  It’s easy to do – the filters are sold at just about every auto parts store and can quickly be installed as a DIY project. 
  • If you suspect your A/C isn’t working properly, have a trusted mechanic check it for leaks or replace refrigerant as needed.

“This week’s extreme summer temperatures are no joke, and heat-related illness can set in very quickly,” says AAA Idaho public affairs director Matthew Conde.  “Make sure that you and everyone in your group stays hydrated and maintains a safe body temperature.”

Adding cooling rags to your emergency kit, in addition to a gallon or two of water, could be a big help.  You may also need to reduce your risk of exposure by completing outdoor activities earlier in the day, including hikes and other recreation.
