Is using ceiling fans and the air conditioner at the same time cost efficient or a waste of energy?
A. Ceiling fans are definitely not a waste of energy. Ceiling fans use very little electricity. Use them to circulate air in the house, to make the house feel cooler. By doing this, the thermostat setting for your air conditioner can be raised to 85 graos Fahrenheit, and still maintain the same comfort as the lower setting.
