Questions & Answers


does the nest require a separate wire for power or will work just with the existing wiring

Asked by kman December 23, 2016

can the nest work with the existing wiring i have now

Do I need to turn power off at the main breaker?

Asked by Keith January 5, 2016

It's easier to just turn off switch on side of furnace. Or the breaker on the front of an electric furnace and heat pump air handler.

does the thermostat require a hub to operate

Asked by bill April 7, 2018


Does it matter what heating and cooling system you have to use this product

Asked by Jay17 April 2, 2018

Yes it does. Most HVAC systems with a 24v control circuit can be controlled by a NEST. To be sure your system is compatible go to the NEST web site and enter your system’s information. Or you can ask the service person who maintains your system.

Will this work with xfinity wifi network

Asked by tld869 February 17, 2020

Yes, Nest thermostats will work as long as it's a broadband internet connection. While 3rd gen Nest Learning Thermostat and Nest Thermostat E can connect to either 2.4GHz or 5GHz bandwidths, older versions of Nest thermostats can only work with 2.4Ghz bandwidth.

How difficult are these to install? Are the installation instructions hard to understand

Asked by Vernon June 15, 2018

Mine was very simple to install, remember to identify each wire with the stickers that come with the instructions.

My furnace is old 1995 will the nest work with it?

Asked by Kk August 20, 2018

This was a present. However, the recipient had it installed in a house whose furnace is much older than 1995. So, I'm thinking it will work in your house Best to check with NEST company.

the property i want to install is vacant. can I control via cell phone if there is no wifi at the...

Asked by Rico November 29, 2018

No. A WiFi connection is necessary to control a NEST remotely.

Is this thermostat will work without Internet service. Just in my wifi area from my router? Thanks

Asked by AP May 1, 2018

Correct. It should only need to connect to wifi.

heating only feature

Asked by Curious June 4, 2016

Yes it will control heating only. The CO and Smoke sensors will communicate with the thermostat to turn off the furnace automatically if CO or smoke is detected, assuming of course that the thermostat is still working properly. Mine needs to be factory reset a few times of year to do what NEST claims it is supposed to do.

Sharp design ! Easy to use. I had a problem w the trim kit not fitting my device so I’ll be returning it after my next one comes in . It actually was featured as going together so I trusted that . But oh well that’s life . I’ll be all set this week .

Set it and forget it
This smart thermostat takes one thing off your mind. There are many programmable thermostats out there, but this works with many smart devices and has an app to change temperature. I can set it anywhere if I'm in bed, vacation, or about to head home it lets me have peace of mind for my gas furnace savings. It also can use your location feature on your phone to turn control the thermostat if it being used or not when you are nearby or away from home. I use Alexa and it is easy to program and to setup like a programmable thermostat depending on the season, time, and weather. Doing this the thermostat also can learn your habits and automatically adjust for it. I rarely touch my thermostat now as is it automatic. Pros: Learns your habits, easy of use, app available, programmable, Alexa Google devices enabled, saves money, phone location uses, sleek looking

I've used about every generation of the nest thermostats personally and they've been rock solid for me. The key is always installing the common wire. Nest stands behind the product and getting replacements for bad units has never been a problem. As a pro installer as well I have nothing bad to say. A lot of hvac techs complain about the product but really it comes down to widespread ignorance in the hvac industry .

I love that it was an easy installation. Please disconnect circuit to thermostat. It is aesthetically pleasing to the eye and easy to read in color. I love the feature of being able to see the weather (outside temperature) and icons for sun, cloudy, rain, etc. More valuable info than setting it on clock. However, my unit will not connect the app to use remotely on my phone. I heard this is an issue; but I didn't purchase it for that. It will learn when I am not home and adjust the temperature based on my personal settings. Plus, it earns you an rebate from your power company!

WIFI Chip Failure!
Quality :
Value :
Do your research before buying this product! You have been warned. WIFI chip went bad in mine in less than 6 months. Their customer service is non-existent. Chat only, no phone support. Warranty says 2-years, but they will not honor it. Horrible cheap product. Features are awesome when they work, the problem is they are not reliable. Search online for Nest WIFI chip failure. Then make your decision. I recommend buying a different brand altogether.

I really like this product. Installation was a breeze and it gave my room a nice upgraded look. It wakes up when you walk by it, which is pretty cool, as I sometime use it as a night light. Overall great product.

Great product. Had to return this though because there was a used one in the factory sealed box. Great staff at HD. No hassle returning it but they were sold out of this color so I got another one.

The old thermostat didn't seem to be working properly so we decided to go hi tech with our new purchase. I'm so glad we did. We had a new A/C unit installed in September 2016 and It just didn't feel as comfortable in the house as I did in the past. This thermostat shows the humidity also which is perfect. You should know what the humidity is in your home. This proved to my husband we have high humidity. I have a repair man coming tomorrow from home depot. We just purchased the Nest thermostat and extra sensor yesterday. But it seems to cycle the airconditioner much better so far. It was easy for my husband to install and I already got back my rebate from the Illuminating company!! Best part I could turn the air conditioner down after I go to bed without getting up!!! The only downside was one of the clips was broken on the unit and my husband had to return the first one. After he had installed all the wires.

The thermostat works well, seems a like a little much for what it actually does. But most importantly it DOES NOT qualify for the SCE rebate like they claim.

The Google nest is a great product! This system controls your temperature in the house through learning your habits. Already my electric bill has gone down. You can also set your own schedule through the Nest app on your phone or your computer. At night if i want a little cooler, i just get my phone and go through the nest app and change it. Easy Peasy! I am also 67 years old woman and installed the Google Nest by myself. I watched their video on YouTube and also read the instructions. Very simple to install. I give Google Nest the highest rating! I also plan on installing the Google Nest Secure for my home security.
