Customer Ratings & Reviews

My problem with this thermostat is that it does not do one of the two essential things a thermostat is actually supposed to do: heat your house. The Google Nest Smart Thermostat is an expensive piece of garbage. It worked fine for the first few weeks, but then it began to delay heat by 2-3 hours. If I set the temperature to be 70 degrees by 8am, the heat wouldn't kick on until about 10am, and then it would take another hour to get up to the desired temperature. My previous, 14-year-old, AAA-battery-powered thermostat never had this issue. I've spent the last month troubleshooting. I even had an HVAC tech look at the furnace, and there were no issues with it. So we installed a common wire because we'd seen online that pretty much everyone who didn't have a common wire had similar issues with the Nest. Even with the c-wire, we still have the same issue. The heat takes hours to turn on in the mornings, and since we work from home, we're wearing thick sweaters, slippers, and sometimes even thin gloves inside our house until about 11am every morning. I missed the return window here at Best Buy (because it didn't have issues until after the return window closed), so we contacted Google, and after an hour of troubleshooting (that I'd already done on my own, but the customer service rep insisted we had to do), the only solution they offered was a replacement of the base. When I asked for a refund they refused. Odds are I'll be out $250 and end up throwing out this replacement thermostat that won't heat my house during the coldest months of the year. I'll be re-installing my 14-year-old thermostat in the meantime. My advice would be avoid this product like the plague, even if you have a common wire. Old, dead technology with no customer service or software updates is more reliable than this flashy, useless garbage. If Best Buy offered in-store credit for a return, I'd take it in a heartbeat at this point.

Really good nice to be able to change temperature when your away from home ! It goes to economy mode when your gone to.

Con: Seems only Nest Thermostat is round on market, also it can choose color to match my wall. Pro: the mounting plate is not matching the original screw holes which left over from previous thermostat

Easy to install and works with my 30 years old air conditioning system!

Works as expected. I bought an Open Box Excellent condition, but the product was all scratched... The most interesting thing I found on the stickers on the box: 11/13/2024 the product condition was rated good condition, and the second sticker from 12/10/2024 indicates that now the condition is excellent (if you wait another month, then apparently its condition will be rated as new). The product itself in fact looks like fair condition... For me it was a very unpleasant and sad experience, because I needed it urgently and I had to drive 60 miles to pick it up... I would like to warn everyone who buys an open box - check it immediately and on the spot...

I've had issues with 2 of these either prior to the 1 year mark or after. If you buy it get an extra warranty.

I like Nest as you can set the carol from anywhere. Don't have to return to a hot bedroom anymore.

Every smart and helpful and going to buy my 2 smart

The Nest Learning Thermostat is a great addition to our smart home features. It is so nice to know that I am saving energy and money with this product. And, being able to control the temperature from the app on my phone, wow, am I just getting lazy or what!

First off got this for a freaking steal 66 bucks with tax on clearance at home depot…NEW!….. definitely didnt want to pay full price and I definitely didnt wanna grab the 4th gen since reviews say its a step back and i was gonna go with the lower model but this was the one I really wanted …. 1. Install was easy, i have an older house built in the 50’s and was suprised this would work… just labeled the wires and relplace the old honeywell one that was here when we moved in….. 2. App setup was where things got wonky the device kept restarting itself while trying to connect to app but some how i got it on one of the restarts and it connected.. i love that i can control it in my google home app but requires nest app to set up and to get most out of controls… 3. The device itself it premium feeling and looking and has some weight to it and looks beautiful on my wall, I was originally gonna go with silver but glad i grabbed the last white one they had cause it just looks flawless…. 4. Software on the device itself is easy to use but how to click it took me a munite but that could be user error/air headedness lol……. Overall for the price i paid i love it cant wait till next summer to see if it actually helps me save money on the electric bill….. also the packaging was first class came with a neat little screwdriver and wall plate

Great thermostat it really learns the temperature you put when you leave and goes back to what you had it before you left . Love it i recommend this product!

The thermostat is by far the best I’ve ever used, and it’s very user friendly.

I can't say enough good things about the Nest Learning Thermostat. From the moment I installed it, it has completely transformed the way I interact with my home's heating and cooling system. First off, the installation process was a breeze. The Nest app guided me through every step, and I had it up and running in no time. The sleek design of the thermostat looks fantastic on my wall, and the white color complements my decor perfectly. The real magic happens once you start using it. The Nest thermostat quickly learns your preferences and adjusts the temperature accordingly. Over time, it has become incredibly intuitive, anticipating when I'll be home and adjusting the temperature to ensure maximum comfort while saving energy. The Wi-Fi connectivity is a game-changer. Being able to control the thermostat from anywhere using the Nest app on my phone is incredibly convenient. Whether I'm at work, on vacation, or just lounging on the couch, I can easily adjust the temperature to my liking. One of my favorite features is the energy-saving reports. The Nest thermostat provides detailed insights into my energy usage, helping me identify ways to save money and reduce my environmental footprint. It's empowering to see the impact of small adjustments on my monthly bills. The compatibility with other smart home devices is also impressive. I've integrated my Nest thermostat with my Google Home, allowing me to control it using voice commands. It's like living in the future! Overall, I couldn't be happier with my Nest Learning Thermostat. It's reliable, user-friendly, and has significantly improved my home comfort while saving me money on energy costs. If you're considering upgrading to a smart thermostat, look no further than Nest.

TLDR: If you know how low voltage systems work, buy it. If you are not comfortable with HVAC troubleshooting, this may not be for you. Yes this thermostat is great to use. However, the setup could be difficult for so many folks that don't have an understanding of low voltage systems, and even for some DIYers. I started using it with 2 wire oil fired boiler to know how many hours my boiler runs. It is perfect for that. I used it just as a 2-wire thermostat with Rh and W. I have an understanding of how things work and I easily set it up with no issues. However, just like any other 2-wire thermostat without battery, you need to keep boiler switch on in order to have power through it when using 2 wires only. Many reviewers don't know why their nest learning thermostat doesn't work and rate it low and it's sad to see that. Even HVAC techs visiting my house warn me to not use nest and I always show them how easy it runs. I recently switched to a gas 2-wire 24V system and installed another 24V transformer for Google doorbell and other LV systems for my house and now I run it with the boiler off in the summer. Why do I run it in summer? Because I have Google temperature sensors all over the house and it gives me relatively humidity reading near the thermostat and temps in the house so I can run window ACs where needed. When running on 2-wire system, it did hum, but barely audible beyond a feet. Installing 24V external transformer with C/Rc wire combination resolved that (see photo - please excuse wire colors). There aren't many videos on how to do that, but you can do it. No wonder HVAC techs don't recommend it because it is so versatile and easy to troubleshoot. Don't rely on Google support because they don't know anything. Trust someone with knowledge in low voltage systems and you will be fine. Other functions in the thermostat are cherry on top and I am waiting to use another one on a split system in future. I don't care about nest/home app being separate. Are there any competitive thermostats at lower price? May be. Cheaper ones may not have relative humidity and analytics. Honeywell is comparable, but it's just a rectangle and Google learning thermostat does look good on a wall with its round shape. The touch and ring are smooth as well.

I picked up the Google Nest Learning Thermostat for a new home, switching from an Ecobee I used previously. The design is sleek and modern—it looks great on the wall and is very user-friendly at the device level. Setup was smooth, and the learning features worked well to adapt to our schedule over time. However, I’ve noticed some downsides recently. The Nest app has become noticeably slow—sometimes lagging or taking a while to load, which is frustrating when you just want to make a quick temperature change remotely. Even more concerning, I’ve seen a large spike in data usage coming from Google API services tied to the thermostat. It’s not something I expected from a smart thermostat and definitely raises some questions around efficiency and background activity. In terms of core functionality—controlling temperature, scheduling, energy-saving tips—it performs well. But the app experience and data consumption are things to watch, especially for those with limited bandwidth or who monitor home network usage closely. Overall, it’s still a solid smart thermostat with great design and automation features, but it could benefit from some software and backend optimizations.

Installation of the Nest thermostat was straightforward with all of the necessary parts and labels supplied. The online help through the Nest website helped to provide confidence that the installation was being done correctly. The set up was simple and straightforward. The connection to the wireless network was pretty much self driven. Pretty nifty to see the little puck go through it's paces. The entire installation and set up took 30 minutes. As a thermostat it works just fine. A little expensive maybe but we were leaving on a trip during the heat of the summer and we wanted to be able to monitor the house temperature and have the option to have the temperature at a comfortable level before we got back without asking someone to come into our house. Four hours from home we used the app to set the temperature back to a comfortable temperature and the house felt great when we walked in the door. The Nest app has worked fine on our Android and Apple devices. The ability to see the history of how much the A/C unit has run over the last week or two is interesting.

We love this thermostat. It is easy to install and program. My house feels cooler with the AC on and it lights up when we walk past is to tell us the inside temperature of the house and what it is programmed to be. It will also troubleshoot to tell me what is wrong with it if it is not working. For example, when we first installed it, one of the wires was not “ seeded” properly and it told us which wire to fix. It looks great on the wall

So easy to install. The instructions will walk you through the steps so you really can't make a mistake. It looks fantastic on the wall, the main display is high resolution so it is easy to read onscreen text. And operation is just as easy; i was amazed at how quickly it picked up our weekly and daily patterns. After a couple weeks, we hardly touch the thermostat at all. I like that it can be controlled remotely, and that it also links to other home control applications. Although I don't use the feature very often, it is nice to know it's there if needed. It's too early to tell for sure if our utility bills will go down or up, but it appears to be slightly lower so far. Even if there's not a significant cost savings, the control features make this well worth the price.

I did a lot of research on these smart thermostats before purchasing this style. I have a heat only boiler that has 5 zones, and this particular one, was the only one that was pretty much assured that it would work with my system. It is a 2 wire system, with no common wire. I was able to hook these up with no issues what so ever! They charge fine, and there was no need for the extra adapter that could be purchased seperately, to hook to the boiler. So far, I have installed 5 of these thermostats, to upgrade our old school Honeywell mercury thermostats. Do your research, but this thermostat is wonderful! I love that I can control my thermostat through the Nest or Google Home app, so no worrying if you leave, and wonder if you remembered to turn down the heat. I also have them installed in our rental units, and I can make sure that the tenant didn’t leave the heat on 70, and leave for days or leave for a 12 hour shift. You can control all the thermostats from one app, so it is wonderful! I would highly suggest these thermostats for anyone that want to make their home a little smarter.

This device is fantastic to control the temperature of your house from your phone. It looks great on the wall and its easy to install and to use.
