What Should Fan Setting Be on Nest

When it comes to your home’s HVAC system, there’s a lot to consider. But one of the most important questions is: what should the fan setting be on your Nest thermostat? Nest offers three different fan settings – Low, Medium, and High – and which one you choose will depend on a few factors.

Let’s take a closer look at each option so you can make the best decision for your home. Low Fan Setting The low fan setting is ideal for those times when you just need a little bit of air circulation.

It’s perfect for rooms that are already comfortable or if you’re only going to be in the space for a short period of time. This setting will also help to reduce energy costs since it uses less power than the other two options. Medium Fan Setting

The medium fan setting is a good choice for most situations. It provides enough airflow to keep things comfortable without going overboard (and driving up your energy bill). This is typically the best setting to use during the spring and fall months when temperatures are moderate.

How Do I Set My Nest Thermostat to Fan Mode?

There are a few different ways that you can set your Nest thermostat to fan mode. The first way is by using the Nest app. You’ll need to open the app and tap on the settings icon in the top right corner.

From there, tap on “Fan.” From there, you can choose how long you want the fan to run for (15 minutes, 30 minutes, 1 hour, or 2 hours) and then tap “Done.” Another way to set your Nest thermostat to fan mode is by saying “OK Google, turn on the fan for [length of time].”

For example, you could say “OK Google, turn on the fan for 15 minutes.” Once you’ve said this command, the Nest will automatically begin running the fan for that amount of time. The last way to set your Nest thermostat to fan mode is by using voice control through the Google Home app.

To do this, open up the Google Home app and tap on the Devices icon in the top right corner. From there, find your Nest thermostat and tap on it. Then scroll down and toggle on “Fan Mode.”

After that’s been turned on, you can say “Hey Google, turn on/off my [thermostat name]” and it will respond accordingly.

Should the Fan Be on Auto Or On?

There is no definitive answer to this question as it depends on personal preferences and the specific circumstances of the room in question. However, some general guidelines can be followed in order to make a decision about whether to use the fan on auto or on. If the room is small and well-insulated, then running the fan on auto may be sufficient.

This will ensure that the room is evenly cooled and that any moisture is quickly removed. However, if the room is large or poorly insulated, then it may be necessary to run the fan on in order to achieve desired results. Additionally, if there are multiple people in the room who have different temperature preferences, using the fan on may be more effective at accommodating everyone’s needs.

How Do I Set the Auto-Schedule on My Nest Thermostat?

If you have a Nest Thermostat, you can set it to automatically adjust the temperature based on your schedule. To do this, open the Nest app and tap on the Settings icon. Then, tap on Auto-Schedule.

On the next screen, you will see a list of days and times. For each day, you can set a different schedule. To do this, tap on the day and then use the slider to select the time period during which you want the Nest Thermostat to be active.

You can also tap on the + and – buttons to add or remove time periods. Once you have selected all of the days and times that you want the Nest Thermostat to be active, tap on Save. Your changes will now be saved and applied to your Nest Thermostat.

Why is My Nest Thermostat Fan Always On?

If you notice that the fan on your Nest thermostat is always running, there are a few possible reasons why. First, it could be due to the Nest’s auto-fan feature, which kicks the fan on periodically to help circulate air in your home and keep things comfortable. Additionally, if your Nest is connected to a humidifier or dehumidifier, the fan will also run when those devices are turned on.

Finally, if you have an HVAC system with an integrated blower motor, the Nest may turn on the fan whenever it runs a heating or cooling cycle – even if the temperature in your home isn’t changing. If you’re not sure why your Nest’s fan is always running, contact customer support for more assistance.


If your Nest Thermostat is having trouble keeping up with the temperature in your home, you may need to set the fan to “Auto.” This will ensure that the fan runs when the Nest Thermostat detects that the temperature in your home is rising. Here’s how to do it:

1. Open the Nest app on your phone and tap on the thermostat icon. 2. Tap on “Settings.” 3. Scroll down and tap on “Fan.”

4. Tap on “Auto” to turn it on. You can also choose how long you want the fan to run for by tapping on the “Duration” option and choosing a time period.
