When I was younger, my parents always called the air conditioner simply "air" ('Turn on the air, turn off the air, etc.) Once we were driving and the air was on, and my mother said, "Don't roll down the window or the air will go right out the window?" Of course, she meant just the cold air, but I thought she meant the whole machine would be torn from the car and go flying out the window. I was always very careful to never open my window.
