If you are investing in a new ceiling fan for your home, you will want to find a design that operates efficiently and conserves as much energy as possible. In this week’s Fan Facts with our resident fan expert, Hugh Prosser, we give you tips to find an energy efficient fan by understanding different fan motor types, looking out for the Energy Star label and properly acknowledging a fan’s airflow metrics.

DC Motor Ceiling Fans

Ceiling fans with a Direct Current (DC) motor are the most efficient type of fans available today. In opposition to AC powered ceiling fans, DC ceiling fans require less energy to operate — up to 70% less energy — by only requiring electricity to start up the motor of the fan while a magnetic drive keeps it spinning. DC powered fans also offer up to six fan speeds compared to the common three speeds found in AC ceiling fans.

Skylon Ceiling Fan by Monte Carlo Fans

DC motor ceiling fans like the Skylon Ceiling Fan by Monte Carlo Fans appeal to a contemporary aesthetic, while also providing escalated efficiency to help you conserve electricity. In addition to Monte Carlo Fans, manufacturers like Emerson and Casablanca Fans also offer noteworthy fan designs with DC motors.

Instead of guessing at the efficiency of a fan design you like, you can look to the official Energy Star label to know with certainty that it operates as efficiently as possible. Ceiling fans with an Energy Star Qualified label are guaranteed to be efficient by the Environmental Protection Agency (EPA) and to earn the label, each fan must pass a series of rigorous performance tests.

Additionally, Energy Star ceiling fans must come with a minimum 30-year motor warranty, a one-year component(s) warranty and a 2-year lighting kit warranty.

Energy Star fans make it easy for you, the consumer, to identify a ceiling fan design that is built to reduce its impact on the environment while simultaneously reducing your energy bill.



Understanding CFM & Airflow Efficiency

We covered how to understand Airflow Efficiency in our guide on How To Choose a New Ceiling Fan with the key points being the following:


  • Airflow: A measurement of CFM or cubic feet per minute
  • Energy Used: The amount of power (watts) being used to operate the fan
  • Airflow Efficiency: A calculation of both specifications (Airflow / Watts = Airflow Efficiency)


Energy Guide SymbolWhen shopping for a new ceiling fan at Lumens, you will want to compare and contrast the energy consumption differences by viewing the Energy Guide information for each fan. This helpful information will provide you with the fan’s airflow (by cubic feet) and electricity use (in watts) to give you a calculated airflow efficiency. By properly determining a fan’s airflow efficiency, you will be able to make a well-informed decision when buying your new ceiling fan.
