Product Description

Product Description

The Nest Learning Thermostat learns what temperatures you like, turns itself down when you're away and can be controlled from your smartphone, tablet or laptop.

From the Manufacturer

A Thermostat for the Smartphone Generation

The Nest Learning Thermostat learns what temperatures you like, turns itself
down when you're away and can be controlled from anywhere over Wi-Fi.

Check Compatibility
NOTE: This will take you away from Amazon.com

Let's Stop Wasting Energy

Your thermostat controls about half of your energy bill - that's as much as the refrigerator, lighting, TVs, stereos and computers combined. Problem is, a lot of that energy is wasted heating and cooling an empty home.

Programmable thermostats were supposed to help, but they can be hard to program. Many people never program them. So we made it simple -the Nest thermostat programs itself.
Nest Info

Control From Your Wi-Fi Connected Nest Account

Control your Nest from Anywhere

Simply connect the Nest Learning Thermostat to your home Wi-Fi to control it from a smartphone, tablet or laptop. Change the temperature, view and adjust your schedule or settings, and see exactly how much energy you're using.

Detailed Energy History is available on the Mobile and Web app for the last 10 days. Your Nest Thermostat also sends you an energy summary every month with tips to help you save more.

The Nest Learning Thermostat is secure, private, and reliable. Nest supports HTTPS, SSL and 128-bit encryption.

Programs Itself, Saves Energy

The Nest thermostat learns from you - your temperature adjustments, your
house, your patterns. Teach it well to stay comfortable at home and save
energy when you're away.

Auto Schedule


Turn it up, turn it down. The Nest thermostat remembers what temperatures keep you comfortable and creates a custom schedule for your home. As your life and the seasons change, Nest automatically adapts.

Auto Away


The Nest thermostat uses its activity sensors to sense when nobody's home and turn itself to an energy-saving temperature. Auto-Away works in 90% of homes, even if Nest is in a room you don't use much.



Airwave cuts your AC costs while keeping you cool. It turns on automatically
when your home’s humidity allows.

System Match

System Match

System Match automatically turns on specific energy-saving or comfort
features for you, depending on what heating or cooling system you have.

Personalized for Any System.

Nest knows one size doesn't fit all. So you tell the Nest thermostat what system you have and System Match will turn on specific features to automatically help you save.

The Nest Leaf

The Nest Leaf

The Nest Leaf appears when you turn the Nest thermostat to a temperature that will save energy. It guides you in the right direction.

Energy History

Energy History

See exactly when your system was on with Energy History, then get a summary of your entire month's energy use with the Nest Energy Report. The more you know, the more you can save.



Get the temperature you want when you want it. If your schedule says 72°F at 6 a.m., Early-On will start heating or cooling early so it'll be 72°F when your alarm rings.

Filter Reminders

Filter Reminders

Nest reminds you to change your air filter based on how many hours your heat or AC has run. A clean filter can cut 5% off your heating or cooling bill.

Heat Pump Balance

Heat Pump Balance

Heat Pump Balance works for homes with heat pumps. It minimizes how often you need to use expensive auxiliary heat - just choose whether you want more comfort or more savings, and Heat Pump Balance will automatically adjust when AUX comes on.

True Radiant

True Radiant

True Radiant for radiators and underfloor radiant system gives you a predictable schedule and even heat. No more frustrating guessing about what temperature to set when.

Easy to Install

We designed Nest to be a quick, easy install: three out of four people install Nest themselves in 30 minutes or less. If you're comfortable installing a light fixture, you can install Nest. Everything you need comes in the box. Too busy? Learn more about Nest Certified professional installation at 855-4MY-NEST.

I'm an HVAC contractor who's installed and troubleshooted this product in customer's homes for the past couple years and experienced the good, the bad, and the ugly. Let's start with the good.


-It looks great. Personally I don't really care what my thermostat looks like but I know that is very important to many people and the Nest is unmatched in this area.

-When it works, it is hands down the easiest thermostat to install. The ability to sense wires and automatically configure the thermostat is a cool feature you don't see too often. They have a nifty wizard on their website that where you check the wires you have and it figures out what type of system you have and whether or not it will be compatible. Not that I really care, since this is what I do for a living, but for DIYers who have never done something like this before, it's nice.

-In theory, it can control quite a wide range of HVAC systems, including 4 stages of heating, 2 stages of cooling, dual fuel systems, and humidification/dehumidification.

-The customer service reps do genuinely seem to want to help, and there have been cases of them giving refunds even outside of the return period, or paying for visits by HVAC contractors to troubleshoot issues or repair damage caused by the thermostat.

-The auto away and auto learning seem to work as advertised for the most part and IF, a big IF, you didn't program your previous thermostat, they will save you energy. However your money would be put to much better use by spending 10 minutes reading the manual of your traditional thermostat and programming it (even if its unintuitive, it's not something you have to do often).

As a certified licensed HVAC contractor for 32 years and Certified Nest Reseller in Scottsdale Arizona I have personally re-installed and troubleshot over 50 of the Nest thermostats. We like the Nest and it's concept though we have been experiencing multiple problems with regards to error messages, units operating erratic, systems switching from ac to heat, compressors cycling into internal overload, burnt up control boards and relays to name a few. I do admit it's great for business, though once we show up for service, we now own the call and are responsible for making the system work. The newest problem was this last week on a commercial building with 4 new AC units on the roof and 4 new Nests. We have logged in 6 additional non chargeable hours to troubleshoot and replacements in a 1hr job to change out all 4.
To keep it short, these are the facts;
*Installed 4 nests, all AC units are same brand, 2 Nests are functioning
*Nest #1, installed, ran for 1 day went into heat, troubleshot replaced control cable and determined bad base, replaced with new from supplier. Installed new Nest, ran 3 cycles, began chattering compressor contactor relay (shorted from 26v to 16v) and compressor went off on overload. Replace Nest with conventional thermostat, unit is now operational for last 2 days.
*Nest #2, customer wanted nest in his office, shut off system power, removed Nest head, relocated line in office, reinstalled base and applied power to system, Nest displayed error message on G terminal as no power and system had no fan, removed head metered lines and jumped fan circuit and fan came on. Replaced Nest with conventional thermostat, unit is operational.

I purchased 2 Nest 2nd generation thermostats from the company store this summer. I am an engineer who in the electronics industry. I am tech savvy, build computers, troubleshoot networks, and fix most everything around the house myself.

I liked the look and concept of this product. A thermostat that programs itself, looks great, is easy to operate, and links directly to my multiple iPads and iPhones. There is even a plugin that makes it integrate with my MiCasa Vera home automation controller. It seemed like the perfect fit for our high tech AZ home. I love technology and understand that new products have growing pains, I usually only write positive tech reviews, but enough is enough...

The decision: We had two old tan box thermostats on our walls. They were programmable, but barely so. When our electric bill hit $500 over last summer enough was enough. We invested in two nest thermostats.

The installation: I installed the thermostats myself. I had a few questions so I took a picture of my wires and emailed it to nest. Installation support was good. I was able to get them running within about an hour. There was a minor issue with changing the o to b on one of my systems to get it to cool instead of heat. In AZ in August this is important...

First sign of trouble... I came home from work a few days after installation and on the main house system the fan was blowing but no cooling was on even though the thermostat was displaying blue indicating cooling demand. I turned the thermostat on and off and this resolved the issue. Concerned, I called tech support and the advised me to reaload the software. Really? Ok... Whatever. I did this and a few weeks later the issue happened again. Does not seem like it was ever resolved.
