Ceiling fan vs air conditioner power consumption.

One way to fan out a nasty power bill is to use both air conditioning and ceiling fans in tandem to achieve maximum comfort. Take a look at the charts below to compare the electricity consumption of regular household items. However i measured the power consumption for those modes as well for reference purposes. Fan only means the air conditioner is only powering the fan and isn t actually cooling the air.

A three ton central air unit a common cooling system runs on about 3 kilowatts and costs about 36 cents an hour to run. A good window ac unit runs on 1 2 kilowatts and costs 14 cents an hour to run. Fans can t match the raw cooling power of air conditioning units especially in warm climates but the air circulation provided by ceiling fans or a whole house fan can make a house feel substantially cooler for a fraction of the energy cost of a central ac unit. The power consumption of air conditioners averages 318 watts hourly for a 24 000 btu unit in most american households the power draw of a unit that size ranges from 1 800 to 2 500 watts in most cases.

You ll see some unlikely appliances paired with each other to show where your money is going and to shine a light on high energy consuming appliances you may not have considered. Air conditioner power consumption trumps that of most appliances. We know that the propensity for maximum chill with air conditioners can t be beat and neither can ceiling fans cost to run. Exact energy amounts vary based on the size of the fan s motor but most whole house fans use between 120 and 600 watts according to the national renewable energy laboratory but this is still much less energy than a central air conditioner uses.

Most ceiling fans average between 5 000 6 000 cfm s. Energy costs of fans fans in general do not consume a lot of energy. There are ceiling fans with high cubic feet per minute cfm available at affordable price points. While that s a feature on many air conditioners it s not typically used often.

According to the article. Given their size it s not surprising house fans consume more power than ceiling fans. The average is only 318 watts because air conditioning units automatically cycle their compressors on off as needed. The electricity consumption of a.
