Using a DC ceiling fan to run your AC less

What you’ll need

• The fan remote or app
• A step stool to reach the reverse switch

Step by step

1. 1

   Set summer rotation

   In summer the blades should turn counter-clockwise viewed from below, pushing air straight down to create a cooling breeze.

2. 2

   Raise the thermostat, not the fan speed

   With the fan running, most people stay comfortable a couple of degrees warmer. That setback is where the saving comes from.

3. 3

   Switch to winter mode when heating

   Reverse to clockwise at low speed to push warm air pooled at the ceiling gently back down the walls.

4. 4

   Use the timer

   Set an overnight timer so the fan stops after you are asleep rather than running until morning.

5. 5

   Turn it off when you leave

   Fans cool people, not rooms. A fan running in an empty room is pure waste.

Energy-saving tips

• Low speed on a DC motor uses far less than a high speed, and is usually quieter and pleasant enough.
• Clean the blades seasonally — dust loading makes fans noisier and less effective.
• Pair the fan with your thermostat schedule so both change at the same times of day.
