Do you think it is cheaper to run 5 fans in the house or turn on the central air? I have been running the air for weeks now with the hot weather. Yesterday was beautiful so I opened the house up. Today it is back to being hot again. DH says to turn on the air, but I told him I would just turn the fans on. He says it probably takes more electricity to run all the fans as it does to turn the air on. Which do you think takes more electricity?
