The direction your ceiling fan spins helps create comfortable airflow in your home and can also help cut down on energy costs. 

During summer, your ceiling fan should spin counterclockwise. This will push cooler air downward in a column and help lower your room’s air temperature. In the winter, set your ceiling fan to spin clockwise and at the lowest speed setting. This will pull cool air upwards, displacing the warm air that pools towards the top of your ceiling and bringing it down towards the floor.

Regularly clean the blades, check for loose screws, and lubricate moving parts to prevent noise and wear.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

There are many types of ceiling fans, each with specific features and advantages. Standard ceiling fans are a traditional choice suitable for most spaces and can be made from materials like plastic, wood, metal, or fiberboard. For rooms with low ceilings, low-profile fans are a better fit. Other specialized types include smart fans, which you can control with a smartphone or voice commands, and dual-motor fans that provide increased airflow in multiple directions. For energy savings, Energy-Star certified fans can be up to 60% more efficient than standard models, helping to lower your utility bill. You can also find fans with built-in lights, fans with retractable blades, and large ceiling fans designed for spacious rooms with ceilings between 10 and 25 feet high.
