Customer Ratings & Reviews

I returned this unit. I had a c wire issue and even when fixed this thermostat gave me issues. Didn’t act reliably and google themselves couldn’t assist me with the issue. It would misread the actual temperature in my home.

Thermostat worked well for few months, but now it is giving error and not setting the temperature correctly. I did change the batteries, reset and reinstall it to resolve the issue but still getting the same error.

The schedule does not work. You need to turn it on and off manually. Unfortunately, the price is too high for a simple feature missing. It is a rip off. I wish I just bought a old simple thermostat, so I do not have to turn it on and off manually. I will throw this way and buy another one. It is a waste of time and money!

I bought two of these when they came out on Nov 1, 2020 to upgrade from old honeywell programmable sensors. I have two (2) 24V wire connections: 1 red and 1 white for running my oil furnace. When I first installed them, I didn't see a problem with them, but soon discovered that they were leeching the battery to run. Fortunately, I could still return them and get money back on my card due to the extra time on the holiday return window. However, it took over a month to see this problem and by that point you wouldn't be able to return them under the 15 day policy. I ended up splurging and getting the 3rd Generation Nest Learning Thermostat. It's only been running for a couple of days now, but I have them installed upstairs and downstairs and I'm not seeing any battery leech. If you have 3 wires, you'll probably be fine as you can use one as the C-wire to power your unit. But if you're like me with only 2 wires then my recommendation is to stay away from this model.

I agree completely with KungFuPanda. I have 3 Nest thermostats that are the older versions and everything about this one is significantly cheaper in comparison. I’ve even used the “E” version which was much better than this one. There is no turning dial, the screen is really just a small square and you can see the borders in the display (see photo), and the google home app is far inferior to the Nest app. Even when you adjust the temperature the new sound it makes is irritating. I really hope this isn’t the path that Nest thermostats are heading and that this iteration is just a fluke. I had intended to switch over my mom’s old school thermostats with this one because of a rebate offered by our electric company, but she’s in her 60’s and the lack of a dial would make adjusting the temperature much too difficult. As far as the C wire debate: in my experience the C wire is not needed when your thermostat controls both heating and cooling. In some cases when the thermostat controls ONLY heating or ONLY cooling then a C wire is needed.

Ever since google purchased Nest I have had nothing but problems with my thermostats. The nest thermostats burned out the PC board on my high efficiency furnace. It set me back $1200.00. I had to go back to a basic Honeywell non WiFi manual programable set of thermostats. My HVAC guy suggested I do this to prevent further damage to the new PC board. Apparently the thermostats draw continuous power from Furnace controller and eventually fry the board. Veissmann furnaces will void your factory warranty if they find out that you have Nest thermostats. It says it clearly on their service bulletin. If you value your HVAC system, steer clear of the Nest Thermostats.

The Service at the Lancaster store is terrible. This product is probably fine it just does not work with my model of furnace. When I went to return it I was first told I could not return it because I only have 3 days to return. Then I was told 2 weeks and then I was told I could not return it because it was opened (how else was I to know it would not work). I have installed 3 nests at other homes. In this case, I called customer support and they said I needed some extra wiring. That took more than a week to get and I was out of town for 2 weeks when it came. Anyway, the manager refused to credit my account and take the return. He and his manager were cranky and not even listening. The irony is, while we waiting to addressed I was telling my mom why I always chose Best Buy -- because their customer service is so good. But no more. Not sure if it is just this store or the whole company is changing but I will just order on line as that is easier for me anyway since I travel for work. I try to shop local to help out but not if they are mean.

This devise has major issues I hooked it up in January and have had to change the batteries that I wasn’t even away it used batteries 4 times. I have the better black one and have had a great experience with that one. It doesn’t work without the batteries either so what’s the point of hooking up all the wires pointless. Wasted my money and now I have to find something else that I won’t have to spend a lot of money buying batteries. By the time you find out that you need an arsenal of batteries. The return time has passed. Shame because it looks amazing just isn’t

Nothingng to do with Best Buy! Here, it's all Google. A concept that was Great, Simple and Straightforward has been turned into a non usable, non installable (without major add ons and hassles), themostat. I actually put it aside after installing and seeing that it wasn't working correctly. Re-installed my only partially working Older NEST, that can't be programmed anymore because Google needed to make more money and they've disinfranchised it!

I purchased a reconditioned unit. So I have to pair the unit everyday to our phones in order to use our phones to adjust. The heat setting only blows cold. When it's hot it randomly goes to 78 degrees when we are sleeping so it feels like a sauna when we wake up. I'm sure we purchased the unit that says reconditioned and they did nothing to it. We only had 15 days to return it and by the time we were trying to see if it was us not knowing how to use it or it truly wasn't working it was too late. What I've learned not to buy reconditioned items from Best Buy.

I have bought two Google nest thermostats in the last year and I continue to have issues with them dropping offline. Then when I try to get them back online it takes multiple retries. When you look up the error codes online, they are useless! I am absolutely done with them!

Had nest gen 2 and worked great. Installed Nest smart and it would not connect to wifi. You can not manually set it up either. Researched and have heard this is a common problem. Went with Ecobee premium and no issues.

So far google nest products have been nothing but junk. This is no exception. Google nest video doorbell died within a few months. Google nest temperature sensor died after a year. This thermostat needed to have a power module sent to me by google (they offer it free because they know they screwed up on the design). Finally got that figured out no thanks to their terrible installation instructions (ended up watching video on y-tube to get it right). Wifi function worked for about a month. Now no matter what i try it reduses to connect to the wifi. The app is useless, their tech support online and in app is a joke. Save your money and buy an Ecobee.

Hard to get it programmed. My app keeps saying that it cannot connect and the last time I tried it said it is not compatible with the wiring at my house. Pain in the butt. I went to send it back and was informed that it was too late and the "return window" passed by 2 days. I have had several people try to do it so that took time, plus I am in the middle of moving and construction.

As of this writing, I have been fighting for a YEAR to get this thing to work properly. I spent countless hours on the phone with just getting the thing to connect to the app!! Then it kept dropping power. And then the internal temperature it showed was very high so I had to pump my heat all the way up to get it to turn on and warm the house. I had heating bills over $200 last season because of this thing. And the worst part is Google has not been helpful in getting a replacement. So I am choosing another brand. Would give five THUMBS DOWN for this overpriced piece of crap.

This AC thermostat is horrible and unfortunately I can't return it. My previous thermostat would allow me to either turn the fan completely off or have the fan on auto. This thermostat has no option for the fan to run on auto. It's supposed to also have an option to turn the fan off completely and run it intermittently, but even though I've followed the instruction in doing this, it still runs constantly. Since it's running all the time, my electric bill has gone up so high. It was an open box purchase, but it was labeled as "EXECELLENT CONDITION". These open box items should have a longer return time frame because in my case, I was not aware that there was a problem and a defect until I could have my AC contractor verify this.

Worked for less than a week then kept giving error codes. Looked it up and alot if people have the same issue. Retunred in and installes old thermostat and problem was fixed.

The app is terrible and it has intermittent connectivity issues.

Slick looking, eady to install. But..,intermittent issues that I never experience on the earlier generation. Trying to get a refund from google

I had to purchase this as my previous nest thermostat quit working the coldest day of the year. The one that failed kept showing the temperature going up and wouldn't read the correct temperature. This new one had a bad mount plate (not sure of the correct name) luckily I was able to the previously failed thermostats plate. Also when troubleshooting the failed thermostat I reached out to Google Nest support and they tried to blame my wifi signal for rising mis read temperatures even after I disconnected the wifi from the thermostat. I understand that a failing wifi chip could overheat a device but dont blame the wifi signal that isnt connected to said device for it. They even recomened I replace my router before replacing the thermostat. Bottom line is be cautious with this thermostat the failed one lasted about 3 years. It costs more than some smart thermostats. But like most electronics these days, QA and support seem to be lacking.
