What Should Fan Setting Be on Nest
If you have a Nest thermostat, you may be wondering what the ideal fan setting is. After all, the fan can account for a significant portion of your energy bill.
In general, it’s best to keep your fan set to “Auto.”
This ensures that your fan will only run when the Nest detects that the temperature in your home is rising or falling. By running only when necessary, your fan will use less energy and help keep your energy bills down.
There are a few exceptions to this rule, however.
If you live in an area with high humidity, you may want to consider setting your fan to “On.” This will help circulate air and prevent stagnation, which can lead to mold and mildew growth.
Similarly, if you have pets or allergies, you may want to set your fan to “On” even when the temperature isn’t changing.
This will help remove pet dander and other allergens from the air and ensure that they don’t recirculate throughout your home.
Ultimately, the best way to determine what settings work best for you is through trial and error. Experiment with different settings until you find a combination that keeps you comfortable while using as little energy as possible.

Should the Fan Be on Auto Or On?

Finally, tap on Save.
Why is My Nest Thermostat Fan Always On?
If your Nest thermostat is set to Auto and your fan is always on, there are a few things that could be happening:
-The ambient temperature may be too low for the fan to turn off.
-There may be something obstructing the Nest’s ability to properly sense the temperature, like a window being open or a heater being on in the same room.
-Your furnace may be set to run continuously.
