So, the most it can cost you to run a ceiling fan without lights is about $126 per year, which is equal to about $10 per month and the least it will cost you is $19 per year, which comes out to just $1 per month...which in either case, is amazingly cheap.s you can see, the calculated cost to operate the fan with lights off is only $0.0029/hr. If you re-calculate it with the lights turned on, the cost increases by about 300% to $0.0091, but is still less than a penny per hour.
The energy cost of ceiling fans, on the other hand, is much different. Whereas a 2.5-ton central air conditioner uses about 3,500 watts and a window A/C unit typically uses between 500 to 1,500 watts, a ceiling fan uses only 15 to 95 watts depending on its size and speed.ooking at those New York Times statistics that compared the cost of ceiling fans versus air conditioning a little further, we can do the math on the monthly costs: â¢ A central A/C unit would cost about $129.60 per month. â¢ A window A/C unit would cost about $50.40 per month.
