Ceiling Fan Vs Air Conditioner Energy Use
Ac why ceiling fans are here.
Ceiling fan vs air conditioner energy use. There are ceiling fans with high cubic feet per minute cfm available at affordable price points. Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost. Most ceiling fans average between 5 000 6 000 cfm s. At typical utility rates a central air conditioner costs 43 cents per hour to operate.

If you were using fans without any air conditioning then of course fans are cheaper. A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. Ceiling fans may also receive an energy star rating if they meet standards for air flow and energy efficiency.
So with that said 5 fans on high use 87 watts each so the total watts for 5 fans is 437 watts. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. And the watts used for an air conditioner is 467.

To get the rating for example. One of the reasons people purchase fans over air conditioners is to save energy. Your mileage may vary with this method. The cost of air conditioning vs.
The fan mode and switches are one such example. Seer is calculated by dividing an air conditioner s cooling output in btu by its energy consumption in watts. A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use. I will assume for arguments sake that no one is honestly considering getting ceiling fans instead of air conditioning as this would be a poor choice unless you lived in the north like bozeman montana where it is cool most of the year.
