Customer Ratings & Reviews

I have a zoned heat pump system, with separate thermostats on each floor. I now have three Nest 3d G thermostats to give me full coverage. They work together like a charm. I especially enjoy not having to go to the third floor to adjust/monitor temp up there -- the app works great. Easy install and easy operation.

If I get too hot (yeah, I'm at that time in my life), I don't need to get out of bed to turn down the heat in the winter, or turn on the AC in the summer. I just pick up my phone and control the thermostat from bed. Also, I can do it when I'm out, to make sure the house is at a good temperature when I get home.

Easy to install and setup, looks great, easy to use

This is the second thermostat to add to my home. The first was easy to install, set up and use. This second one was a bit more challenging setting up. Had challenges finding the internet. Four months into use the item totally lost internet connection. It still worked but there was no online controls. Called customer service and spent a good amount of time troubleshooting. It was finally determined it had was faulty. Replacement is on the way.

This is a great first piece to your smart home and one that delivers its value over time as it learns ways to improve the efficiency of your heating and cooling. The ability to heat up the house on the way home is amazing in the winter. Just make sure it's compatible with your HVAC system before you purchase.

Works great. Easy to operate. Links to my Amazon Echo.

Easy install, even for a novice. Incredibly smart and intuitive.

We love that this thermostat will know when we are not home so it automatically adjusts the temperature of the home. It has probably paid for itself in the first couple of years by the feature alone. It was simple to install through the instruction included, as well as, the customer service number incase you run into an issue.

love this Thermostat and all nest products!!! so user friendly and great customer service!!! I love that I can control it from my phone!!!m Thanks Best Buy for your customer service as well...

We have had this over 6 months and we love it. It’s nice being able to change the temp when your bedrooms are upstairs and the thermostat is downstairs. Just go to the app and adjust to your hearts desire! Not too mention it does seem to be much more effeicient than the standard thermostat. All in all it was an excellent purchase.

It looks really nice. Very sleek, seems to work fine so far though it's only been a few weeks. Haven't really used everything it can do.

Sleek, easy to use and less bulky than my former watch.

Love the Nest. Very easy to install and setup. Works great!

Installation was a breeze. It looks and works great.

So good! Easy to use, and just a great product overall.

Great product. Really comes in handy and is easy to use

I installed my thermostat and noticed my furnace was cycling often. I first thought it was an energy conservation feature in Nest. I then received an email from my thermostat telling me to check my furnace air filter. Sure enough it was dirty. Changed the filter and the furnace quit the short cycles. Its a HVAC tech as well as a thermostat.

This item works great and is wonderful to look at as well

I have been using NEST products for a long time, and by far the NEST Thermostat is one of my favorites. The ability to control the temp and schedule is a MUST HAVE. I currently live in an apartment and even switched my unit in the apartment with a nest (took about 5 mins to do) and of course I can put the original thermostat back when I leave.

This is my 2nd Nest 3rd Gen Smart Thermostat. 1st was installed 6 mos ago for our upstairs HVAC zone. I like it well enough to get another for our downstairs HVAC zone. Best lesson learned from 1st Nest: Don't let anyone install a Nest thermo without having a hot (power) wire connected to the Nest otherwise when the Nest's backup battery runs out the Nest will die disabling the HVAC. I had to have an licensed electrician diagnose the problem & run a hot wire to the Nest because the Nest installer did NOT know about the necessity of the hot wire because the Nest worked great once installed...for 30 days, then while we were away from home during winter weather everything shutdown. ! I knew the system was out as monitoring it online indicated so. At anytime, I can check on the Nest using the Nest App. I can also ask Alexa for very limited information like, "what's the temperature in the upstairs mid bedroom?" The App provides much more extensive details and options, i.e. adjusting the temperature. Upstairs is empty-nested, so there's usually no one there to use it, so I haven't had any experience yet with using it's "smart" capabilities. The new one will be smart enabled so it can learn our habits via experience and make adjustment without having to make on-the-spot personal adjustments. I am anxious to see how that works out! Most significant downside: Alexa is not yet sophisticated enough to do all she's asked to do regarding the Nest thermostat...might have to wait for the development of a "Smart Alexa" to be capable of working with a "Smart Nest" thermostat! Regarding the Nest Sensors. I love having the option of determining which of the upstairs rooms need to be comfortable for occupants. The sensors can allow that. Smart suggestion: Check online with your area's gas/electric service provider for rebates for installing Smart Thermostats. I got a $125.00 rebate for my 1st and have application for $100.00 rebate for my 2nd.
