Now that we’ve discussed lifespan and warranties for Nest Thermostats, let’s discuss things you can do to extend the life of your Nest Thermostat.

Best Practices To Extend The Life of Nest Thermostats

Although it is not uncommon to replace items when they’ve reached the end of their life, the best thing you can do is extend the life of your items to the best of your ability. Using the following guidelines may help extend the life of your Nest Thermostat:

  • Ensuring operating temperatures
  • Standard upkeep of care and cleaning your thermostat
  • Avoid magnetic fields
  • Receiving proper service and support

In the next few sections, we will discuss these guidelines in order to keep your Nest Thermostat in tip-top shape to get the most life out of your thermostat.

Operating Temperature

Do not use the Nest Thermostat at ambient temperatures lower than 32 degrees Fahrenheit or higher than 95 degrees Fahrenheit. If your Nest Thermostat is operating lower or higher than these temperatures, it is very likely that your thermostat will malfunction in some form or fashion.

Most homes range in temperature from 68 to 76 degrees Fahrenheit, but if your power happens to run out for a long period of time due to inclement weather or other unforeseeable actions this may cause the Nest Thermostat to prematurely go bad.

Standard Care and Cleaning

This may be widely known regardless of the brand of your thermostat, but ensure that your Nest Thermostat remains clean and free of dirt or dust. Regular cleaning of your thermostat will not only provide you with more accurate readings, but it can help avoid requiring maintenance of your Nest Thermostat.

To clean your Nest Thermostat, it is recommended that you use microfiber or other soft, lint-free cloths. This will prevent additional lint or dust from clinging to the thermostat or rough cloth materials from causing scratches. Use a dry cloth for streaks, smudges, or dust.

Use screen wipes or eyeglass cleaner for stains or grime. You may use household soap or bleach-free wipes to clean the back and sides of the thermostat. To disinfect your thermostat, you may use ordinary household disinfecting wipes or 70% isopropyl alcohol-based wipes.

You should avoid the following products or materials when cleaning your thermostat:

  • Avoid solvent and any bleach or bleach-based cleaning solutions
  • Avoid rough cloth materials when wiping the thermostat surfaces
  • Avoid chemical detergents or agents, or powders

Proper Service and Support

The best practice to extend the life of your Nest Thermostat is to avoid unauthorized repairs or modifications to the thermostat. Receiving repair or modification information from outside sources may cause permanent damage to the device and will more than likely affect your warranty coverage.

While you can utilize the Google Nest troubleshooting options that are made readily available via the internet to self-diagnose problems with your system, it is best to speak directly with a Google authorized service provider and, or, have the device repaired by Google or said provider. Customer service and online help are readily available when needed.

Now that we’ve discussed how to maintain the lifespan of your Nest Thermostat, keep reading to learn how to replace the battery on your Nest Thermostat.

Battery Replacement

Some owners of Nest Thermostat may believe that because the Nest Thermostat battery is low or requires replacement, that this means the thermostat life is nearing the end, but this is not always the case.

Similar to charging your phone battery, sometimes your Nest Thermostat will need a battery “pick me up” in order to keep your Nest Thermostat running smoothly. It is not uncommon that you may need to replace the batteries on your Nest Thermostat at times throughout the lifespan of your thermostat. Replacing the batteries on your thermostat is simple and takes very little time to complete. Use the following steps to replace the batteries on your Nest Thermostat:

  1. Remove the thermostat display from the base
  2. Open the back of the display and remove the old batteries
  3. Insert 2 new AAA alkaline batteries
  4. Place the thermostat display back on the base


As mentioned above, the average lifespan of the Nest Thermostat is about 10 years. If you are utilizing your Nest thermostat with the best practices and battery replacement mentioned above, it is very likely that you will get the most bang for your buck out of the thermostat.
