On a hot day and traveling in a car, which method of keeping the occupants comfortable with the A/C is more energy and fuel efficient?
-
Set the thermostat to a lower temperature and keep fan speed to the lowest setting
-
Set the thermostat to a slightly higher temperature and compensate by setting the fan to a higher speed so you can feel cool enough with the breeze
Right, my point was that having the air on at full blast was negligible, barely affecting the efficiency of the car. So the settings probably don’t matter very much.
