Google Nest thermostats are designed to work with most 24 V systems, even older systems. They work with all common fuel types including natural gas, oil, and electricity.


During setup, the Google Home or Nest app will guide you through steps to tell you if your system is compatible with your Nest thermostat before you install it. The app will also give you a custom wiring guide for your thermostat.


You can also check your system’s compatibility before purchasing a Nest thermostat with our online Compatibility Checker. Some systems may require a common wire (C wire) or the Nest Power Connector. Check here for details.
