Overview

  • Improved compatibility.
    It works with most 24V systems, including gas, electric, oil, forced air, heat pump, and radiant, and no C wire is required for installation in most homes.³
  • Better visibility into adjustments.
    Smart Schedule learns the temps you like, and when you like them. It asks for permission to make schedule changes to help you save energy. You’ll receive notifications in the Google Home app, and you can view and accept changes with a tap.¹
  • Beautiful design.
    With a 60% larger display⁴ and Dynamic Farsight, you can see info from across the room.¹ Choose the design – a clock, the temp, weather, and more. It automatically adjusts brightness for the best readability or you can adjust manually.
  • Easy control in the Google Home app.
    Adjust the temperature on your phone from anywhere¹ or by using your voice.⁵ It’s easy to install yourself³ and it’s Matter compatible for simple integration into your smart home.⁶
  • Manage hot and cold spots.
    The Nest Learning Thermostat (4th gen) comes with a Nest Temperature Sensor (2nd gen) and works with any Nest Temperature Sensor. Put a sensor in any room and use the Google Home app to set the temp it should reach at a certain time of day.
  • Savings you can count on.
    Nest thermostats can help save up to 31% on heating and cooling bills.⁷,⁸
  • New natural heating and cooling.
    Your thermostat learns how the temperature outside affects the temperature inside (for example, when the sun coming through the windows will heat the house naturally) and pauses your system to help you save.¹
  • New Adaptive Eco.
    It uses the temperature outside to help find an energy-saving temperature when you’re away and returns to a comfortable temperature within an hour of your return.¹
  • Looks out for your heating and cooling system.
    System Health Monitor helps catch many issues early. And if something needs attention, it can send an alert.⁹
  • Your HVAC heads-up.
    When it’s time to change your air filter, you’ll get an alert based on actual use.⁹ And you’ll get seasonal maintenance reminders.
  • Smart is in the air.
    To save energy, smart ventilation brings in fresh air when outdoor air quality is healthy and most efficient, like when temps are mildest.¹,¹⁰
  • Clean energy made simple.
    Energy Shift from Nest Renew can automatically shift your energy use to cleaner or cheaper times.¹¹
