If you’re planning to buy a Nest thermostat, you might be wondering if they work well enough to be worth the investment. Otherwise, you might already have one but are questioning its longevity. 

Generally, Nest thermostats last approximately 10 years, but some factors can hasten or lengthen their lifespan. Read on to learn more about their longevity and common signs that they need to be replaced.


What Is the Nest Thermostat?


First released in 2011, the Nest thermostat continues to be among the most popular smart home devices on the market. This highly useful gadget not only helps ensure your indoor spaces are always at a comfortable temperature but also helps you save on energy bills. 


The Nest line of smart thermostats uses artificial intelligence (AI) and references a machine learning algorithm to identify your household’s habits and preferences in terms of temperature. 


With a Nest thermostat, you won’t have to come home to a freezing or hot and stuffy home. It will power on the linked HVAC systems before you arrive, according to the schedule it has learned from your daily habits, the seasons and personal preferences. Conversely, it turns itself down when you’re away from home.


Another important benefit you get from a Nest thermostat is energy savings. According to a Google white paper, Nest users in the U.S. saved an average of 10 to 12 percent on heating bills and approximately 15 percent on cooling costs. Since this averages down to annual savings of up to $145, your Nest thermostat will pay for itself within two years or sooner.


Nest Features and Capabilities


Google has released several versions of the Nest. The ones widely available for purchase today are the Nest Learning Thermostat (third generation), the Nest Thermostat E (released in 2017) and the updated Nest Thermostat (released in 2020). 


All models are Wi-Fi-compatible smart devices. The following table provides a brief overview of each one’s features and capabilities.

How Long Do Nest Thermostats Last: Factors Affecting Their Lifespan


Most online sources say that Nest thermostats can last up to a decade. However, Google itself has not released any information about the longevity of Nest thermostats, so the answer to how long Nest thermostats last may depend on factors like frequency of usage. It’s possible that they could last even longer than 10 years as long as they have been installed correctly. 


The batteries installed in your Nest thermostat are a major factor. 


The “Nest Thermostat” model uses two standard 1.5 V AAA alkaline batteries that can be easily replaced if they get low. However, the “Nest Thermostat E” and “Nest Learning Thermostat” models have internal rechargeable batteries that users cannot replace. If these batteries don’t charge or the thermostats aren’t getting enough power, they would need to be repaired or replaced.


Common signs that your Nest smart thermostat is failing include


  • Poor battery life
  • Frequently disconnects from Wi-Fi
  • Sudden reboots 
  • Heating and cooling are short-cycling 


Nest products are covered by a warranty for a limited period. If the Nest breaks beyond this period, you’ll need to pay to have your smart thermostat replaced or fixed. 


This is easier said than done if you own an older version of the Nest thermostat, as parts can sometimes be challenging to find. Whether repair or replacement is the ideal solution depends on your budget and your willingness to scour the Internet and other sources for reputable parts and service providers.
