Ceiling Fan Vs Air Conditioner Energy Use

Yes max in terms of power consumption ceiling fans are more efficient than air conditioners however they don t necessarily have to cost the same or more than an air conditioner.

Ceiling fan vs air conditioner energy use.

Ac why ceiling fans are here. This is done by combining the benefits of both an air conditioner and ceiling fan at a lower cost than air conditioning alone but with more adequate levels of cooling than ceiling fans alone. Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost. If you were using fans without any air conditioning then of course fans are cheaper.

To get the rating for example. There are ceiling fans with high cubic feet per minute cfm available at affordable price points. Most ceiling fans average between 5 000 6 000 cfm s. The cost of air conditioning vs.

So with that said 5 fans on high use 87 watts each so the total watts for 5 fans is 437 watts. A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. So in real time there is not much different from fans to air conditioner. Your mileage may vary with this method.

Department of energy s energy star rating. 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. The fan mode and switches are one such example. One of the reasons people purchase fans over air conditioners is to save energy.

A good ceiling fan it draws only 30 watts to run costing about 1 cent per three hours of use. It may seem logical to think that a fan for an air conditioner is the same as a fan that you use in a room thought this is not the case. Energy costs of fans fans in general do not consume a lot of energy. With this fan you ll be impressed with the unique programmed shutdown that enables you to operate the system automatically at intervals between 30 minutes and 7 5 hours.

A good window ac unit runs on 1 2 kilowatts and costs 14 cents an hour to run. At typical utility rates a central air conditioner costs 43 cents per hour to operate. Units with a seer of 14 or higher receive the u s. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units.

The dollars and cents tip the balance in favor of the air conditioner ceiling fan combo as well. Seer is calculated by dividing an air conditioner s cooling output in btu by its energy consumption in watts. Ceiling fans may also receive an energy star rating if they meet standards for air flow and energy efficiency. According to the article.
