Answer:
Ceiling fans should rotate B. counterclockwise in the summer.
Explanation:
Most ceiling fans have two settings: clockwise, which is good for cooler months, and counterclockwise, which is good for warmer months.
Running your fan counterclockwise creates a downward draft, pushing the cool air down to you. While fans do not change the temperature of the room, they create a wind chill effect, making you feel up to 8° cooler.
Using fans in the summer allows you to comfortably raise the thermostat on your AC, saving energy and money!
