How to Install a Nest Thermostat
It’s easy to install the 3rd gen Nest Learning Thermostat. And it’s quick – most people install it in 30 minutes or less. Grab your smartphone and make sure you have access to your fusebox; you'll need it to turn off the power before safely installing your thermostat. Everything else you need is included with your Nest Thermostat.

Grow Your Nest Family
Now that your Nest Thermostat is up and running, consider expanding your Nest home. Nest products are made to work together. In fact, each of the Nest products below talks to your Nest Thermostat to give you greater control and more peace of mind.
Nest Protect™ smoke + carbon monoxide alarm
Your heating system could be a source of carbon monoxide leaks or it could spread smoke through your home in a fire. If there’s a carbon monoxide leak, Nest Protect can tell your Nest Thermostat to turn off the heat. If Nest Protect detects smoke, your Nest Thermostat can turn off the fan.
Nest Cam™ Indoor
If you have a Nest Cam, it can automatically turn on alerts when you set your Nest Thermostat to Away. So when you go on vacation, your thermostat turns itself down, and Nest Cam turns itself on.
Nest Cam™ Outdoor
Nest Cam Outdoor is beautiful, weatherproof and can help keep your home safe. Security, rain or shine. On your phone 24/7.
