Customer Reviews for Google Nest Thermostat - Smart Programmable Wi-Fi Thermostat Fog + Nest Thermostat Trim Kit Deep Fog

Easy installation, temperature control made easy.

It took me much longer to set up than I anticipated. I have a Honeywell thermostat and decided to update with this one and like being able to control it from an app. I hooked it up and nothing. I couldn't get it to scan that miniscule QR code with my phone. I didn't realize also that the code to enter manually is on that same QR code. When I finally got the display it gave me error code E260 which is no power to Y1. Basically it meant my furnace wouldn't turn on. I re-hooked up the old thermostat to make sure the furnace would still work and it worked fine. I came close to returning the Nest thermostat at this point. My thermostat only contains 4 wires so there isn't a common wire. I found out that you can run the green wire to the common. (One video showed that you had to change the green on the furnace also). I didn't have to do the latter. It seems to work fine so far. I'm running it either manually or with the Google Home app and just tell it to turn on/off the heat. I can also just say " Hey Google" turn the heat up to 70 or such. I work from home so I don't think I'd really use the Nest app that much anyway. Another thing that I don't like is that it doesn't come with the back plate to cover up the area where the old thermostat was. If you want that you have to order the .50 piece of plastic for $14.99. Really? Thankfully my utility company is currently offering a $75 rebate or I probably wouldn't have tried this. I think I will like it in the long run though. Don't throw away your old thermostat though just in case and take a picture of your wiring diagram before you take it apart.

I am a HVAC&R engineer of 30 years, all Nest remote thermostats required a "C" wire to initiate wifi functions. ALL boilers or AC condensers has enough "C" power for 3 to 6 Thermostat (zones) . Nest intentional or unintentional created One Million dollar of profits to the battery industries, using a one million sales forecast, term is called "Financial Engineering". Purchase other brand of remote Tstat where batteries are not required. Stay away from Nest, they are not into thermostats.

Love that it can be controlled from anywhere, but do not like the new side control on the thermostat itself. I’ve had it about a month, not crazy about the preset temperatures, had to go in and change them all, as well as the schedules. Overall it’s a good thermostat for the money just wish I spent more and bought the learning thermostat.

Unlike the other Nest thermostats, this one forces you to use the Google Home app. You can't do anything but change the temp on the thermostat. Need the app to set a schedule or do just about anything. Worst of all, you can't disable home/away mode, only control it from the app, which requires location sharing, which I refuse to do. Guess I should have ponied up for the Nest Learning thermostat.

Works great so far. Easy installation. Turns on when I’m home. Turns off when I leave. Easy peasy.

Nest thermostats working perfectly so far. Trim kit covered my old thermostat box perfectly and the Nest thermostat fits snugly and securely into the provided hardware. Good design.

Works great. Old unit was running my bill up. After month $90 drop in bill

I had a traditional honeywell thermostat in my new home and wanted a new wifi connection device. People recommended google nest. I had it for 3 weeks and unable to get cold air. Been playing around with it on wires and still no success. Returing it and getting one recommended by a professional who came to my house to fix a busted fuse after i tried to connect one last time

Easy assembling, easy set up to schedule

Keeps connecting to all my devices without permission or any sort of warning, no matter how many times I turned off, was turning the room temperature down to 65 and my disable child got sick due to the cold and his intolerance to blankets. Today we replaced with the old one.

I returned it to store. not easy to install..

The nest thermostats are the most frustrating products I have ever encountered. If the wifi goes out for even a second the device disconnects. As the internet is still working, the device acknowledges that it is connected to the wifi but remains "offline" in the app until being manually restarted. Why would it not have been designed to automatically attempt reconnecting? It's insane that you expect people to have to manually restart it anytime there is a blip in the wifi. The nest doorbell is able to handle that just fine but the thermostats are a constant problem.

A lot of money for a cheap piece of plastic but it saved me from repainting when I replaced the thermostat with the nest

Easy to install. Google also provides free power adapter.

Locked up and had to be reset - worried about cold weather

This thermostat works great for controlling in-floor radiant heat with the preheat function.

Couldn't get it to work with a heat pump, so returned it to the store.

Pay extra and get the nest learning thermostat! My parents had problems with this thermostat, but i thought it was user error. I was wrong. I Had the same problem, the thermostat is not stable, kept turning on and off my AC then my heat went on!! I quit, and installed my old honeywell non-wifi thermostat..google needs to improve these !!

It will not hold temps. I suspect big brother is behind this. Works off wifi apps and google nest. You buy it you will hate it.

Easy to install and set up

Setup was easy and easy control of a rental unit from my phone is ideal for cost control !

Not "smart" savvy, so like to read instructions, so we had to find info about operation by reading other reviews rather than from instructions. Once we got it set up, works well. Easier to operate via phone than at thermostat. Kept trying to use nest icon unsuccessfully on phone, but found access via Google home and that works great.
