The motor of a ceiling fan pushes air to move the blades and create airflow. The volume of air moved and the speed of the blade rotation are what differentiate different fans, allowing them to serve for a wide variety of uses.
The correct fan size depends on the square footage of your space. Typically, for rooms up to 75 feet in size a fan with a blade span of 36 inches or less is sufficient. Larger spaces require a fan with a larger blade span or multiple fans.
If you are experiencing wobbling or vibration, check that all screws and hardware are tight, and that the fan blades are not warped or damaged. You can also try gently bending the blades to realign their pitch. Another common cause of vibration is unbalanced blades, which can be corrected by using a kit that includes small weights to balance the blades.
Many modern ceiling fans are electrically reversible, which allows the direction of the airflow to be adjusted by flipping a switch on the motor. However, many older fans are not reversible and may simply need the blades to be pitched with the upturned edge facing down for updraft or downturned edge facing up for downdraft.
A ceiling fan can be made smart by connecting it to a compatible hub and then controlling it from your phone with a dedicated app. It’s a relatively quick, easy and cost-effective way to add some smart functionality to your room.
