How to Set Air Filter Reminders with Your Nest Thermostat

The Nest Learning Thermostat can save you money on your heating and air conditioning bills, but if you aren’t keeping up with maintaining your heating and cooling system, you’re probably not saving as much money as you could be. Luckily, your Nest Thermostat can help remind you to perform regular maintenance.

Granted, your furnace and air conditioner don’t require too much maintenance, but the little maintenance that it does require is really easy. For instance, it’s recommended that you change out the air filter every few months. You may need to change it more or less depending on your usage and household. For example, if you use it less often, you can change it less often, but if you have pets, you may want to change it more often.

However, some people may not be heeding this advice and may have an air filter that’s old and needs replacing. While you may have a fancy new thermostat that can save you money over time, a dirty air filter isn’t doing you any favors, and it’s one of the easiest home maintenance tasks you can do.

One cool feature of the Nest Thermostat is the ability to remind you when you need to change out the air filter in your heating and cooling system, that way you’ll never forget.

Start by opening up the Nest app on your smartphone. The home screen will appear.



Select your Nest Thermostat.



Tap on the settings icon in the top-right corner.



Select “Equipment”.



Select “Air filter reminder”.



Tap on the toggle switch for “Air filter reminder” to turn on the feature. It will change from gray to blue.



Next, select “Last changed”.



Select when the air filter was last changed. If you’re absolutely not sure and are concerned that it’s been a while, go ahead and change the air filter now before you set up a reminder, and then select “This month” when you’re done.



You can also set up air filter reminders right from the Nest Thermostat itself.

Start by pushing on the unit to open up the main menu and navigate to “Settings”.



Scroll to “Reminders” and select it.



Push to continue.



Select “Remind Me”.



Select the month when you last changed your air filter.



That’s it! You’ll be taken to back to the settings and “Air filter” will appear under “Reminders” now instead of “None”.



From now on, you’ll receive reminders when it’s time to change out the air filter in your heating and cooling system. The Nest Thermostat will determine when the filter needs changed after 1000 hours of usage, instead of just reminding you at set intervals every time.

For example, if it’s a particularly hot summer and your air conditioning is running a lot, your Nest will likely remind you to change the air filter more often. However, during the fall or spring, when you may have your system completely off or just running sparingly, your Nest may not remind you to change out your air filter as often. (Annoyingly, you can’t customize this option, though.)

Keep in mind that some users have had some trouble with the Nest reminding them about changing their air filter, saying that it’s been more than several months since getting a reminder, and that if your Nest crashes, don’t be surprised if the counter resets itself. So if you can, try to keep track on your own–and hopefully your Nest will remind you if you forget.
