Typical Electricity Costs. The town of Wellesley, Mass., has estimated the average cost of running central air conditioning in a typical home for six hours a day will use 900 kilowatt/hours (kWh) per month. At a cost of $0.134 per kWh, this amounts to $120.60 per month.A large 12,000 BTU air conditioner, like that in a window, running six hours each day will consume 270 kWh, at a cost of $36.26 per month. A smaller 6,500 BTU room air conditioner will consume 144 kWh at a cost of $19.34 per month. large 12,000 BTU air conditioner, like that in a window, running six hours each day will consume 270 kWh, at a cost of $36.26 per month.
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.
