Customer Ratings & Reviews

This thing is such a piece of crap. It's complicated, and HVAC personnel don't like it when coming to fix the thermostat. The Google technicians are generally not knowledgeable and don't know their own system when you call them up, which makes no sense. Not recommended.

Always wanted one so bought one during Thanksgiving sale, installation was fairly easy followed by all the software updates and things like that, it seemed to be running ok. Cold days here so had set it to 72. Heat kicked off and then after few minutes it turned off and it said it had reached the target temperature. I have two other thermometers, one from my old thermostat (with batteries) and other that shows me humidity and they were both showing the house temp to be 69. So I placed these both thermometers very close to the NEST and bump up the temp to 73. NEST comes on and shuts off the air in few minutes. The nest sensor showing that my room temp was 74 and since the target was set at 73, it shut off. At this point, the other two are still showing 69 and 69.5. So I call support, three separate calls on three separate days and then in the end, their supervisor said that is OK for NEST to be off by plus or minus 5F. So basically in winter, when my nest is showing me 72, my actual room temp could be 67F. I so wanted it to work but now its going back and putting my Honeywell back on. The least Nest support could have offered is a replacement.

I thought this would be a good addition to my home but I was wrong. The install was pretty straight forward everything was working and I was glad to see it working. After a few hours i saw it went offline then i started diagnosis only to find out 1 out of 3 people will have this issue that requires extensive work to fix. There is no easy fix everything will require rewiring the device to work.

I purchased two nest learning thermostats 3rd generation more than 2 years ago. They were great and working fine until they weren't. All of a sudden they're disconnected from the network and failed to find the Wi-Fi network. I have several other gadgets connected to my Google WiFi mesh network, most of them Google products and they are all working fine. I did everything it's suggested on the support page but they are no longer connected to my network and controlled via home or nest app. There are hundreds of the same complaints on the Google forums. Somehow, as soon as the warranty is expired, devices go bad. I don't want to make any accusations but it's fishy that so many products have the same issue all around the same time. I'll just continue using them offline as I'm not going to spend another $400. I'm obviously very disappointed and recommend thinking twice before making a commitment. Keep in mind that you'll be very likely experience the same problems and you'll not be happy then.

I had an Ecobee thermostat and it had the occasional cloud issue where it would either log you out of cloud randomly or you'd be told it could not connect due to back-end issues but the Nest worked for all about two weeks and since then it will not detect ANY WiFi networks, which is leading me to believe it's defective. I tried resetting just the settings and then resetting the entire thermostat but when you go to setup the WiFi it doesn't find a single WiFi network which is unusual in an apartment -- especially considering if I go to WiFi on my laptops, it finds over 2 dozen networks almost instantly. Outside of that, devices like the Logitech Harmony remote that are supposed to be able to control it constantly throw error messages that they can't connect so you end of using your phone for the most part. For all of the trouble I would go back to an Ecobee if the Nest wasn't what was pre-installed by the apartment for energy saving credits. Plus Google was late to the game on using room sensors to make sure rooms were heating and cooling to your preference based on occupancy, which Ecobee had from the beginning and it's also HomeKit compatible so you can control it along with all of your other home automation devices from a single Home app that's already pre-installed on your iPhone (not to mention the setup process is as easy as scanning a barcode and going -- trying to enter the name and password for a WiFi network by rotating a circle around is painful, especially when you consider you have to switch keyboards for upper and lowercase and symbols).

I really wanted to like this thermostat , But A right pain in the A There is no way over ride the temperature without it deciding what temperature it believes your house should be at This could take up to several hours for it to decide when it will turn on the heater Google needs to modify their software to allow humans to override the thermostat temperature Since they are the ones paying the gas and electricity bill

It disconnects from router and draining batteries, I have 940 MB internet from Spectrum and 30 devices connected and never dropped any signals on any devices with my ORBI MESH RBK852, but this product drops signals and showing battery low every three days, I would not recommend anyone.

I have two Nest Thermostats that i purchased and installed in May in my home for two furnace/AC systems we have. Everything was working fine until last week at which time one of the units died. After MANY hours of debugging/resetting and swapping units I determined it was the Nest that had died and after MANY hours on chat with nest support they agreed. After an attempt to have me send my unit back and the send me a replacement we agreed that they would ship the replacement and then have me send the unit back - charging me if I failed to do so. I was to receive an email with confirmation that evening. A week latter and COUNTLESS HOURS on the brain dead support chat later I have no confirmation (although being assured it might be coming) and no next step. Literally every day I have inquired and pleaded my case and each day I get further away. NEST/GOOGLE have hit rock bottom. I am ready to move away and embrace Apple something I thought I would NEVER say. I am a google wifi, pixel 4, nest home, nest thermostat x 2, android developer with Play store apps, etc etc person. What a let down.

After having the nest for a year, I started having significant problems with my AC/Heating unit. Multiple items on the unit were breaking, I wasn't able to switch between AC and heat as the weather shifted, etc. After over $500 in HVAC repairs/service calls, we finally found out that the issue was the Nest. Something went wrong with the thermostat, causing my unit to short out and the box to burn up. After replacing the nest, my unit has been fine. I've contacted google, and they won't do anything to replace it. While it is out of warranty (the warranty is two years, and I've had it two and a half, but the issues started after one year of ownership. It just took us a little bit to figure out it was the thermostat), I don't think a $250 thermostat should go bad after only two years.

I came home to find nest on, in heating mode, at 59 degrees when it is set to 63. I have no idea why, but apparently houses in my area had a very short power outage (less than 5 minutes). Maybe it is related, maybe it's not but this is not acceptable. I am looking for a replacement that can go to heating after a reset, if programmed so.

I spent $250 on this piece of junk and end up wasting $7000. After I changed my old thermostat to the nest, I noticed the room never cooled to my set temperature. I thought my AC system was old and inadequate and replaced the whole system for $7k. The new AC still did not cool the room. Then I noticed the Nest kept going into delayed start, and would stop cooling after only a few minutes. Called customer service, their reps were clueless even though I had wait long time and spent couple hours with them. Apparently this is a problem affected incredible amount of customers. I googled and found many complaints on this. Tried many solutions offered online, and none worked. I had to switch back to old thermostat and now everything worked. If I can sue Nest to get my $7k back, I would. Really the worst purchase in my life. Be warned if you want to buy this piece of junk. If you donot believe me, google Nest delayed start. I would give it negative one star if the option exists.

This thermostat cost me more money than what its worth. Nest have techies developing it, and the techies don't have a clue what HVAC is or means. This thermostat is made to shut down the compressor with out your control, which means your house will get cold. It's made to save the inviorment, not keeping you warm. After all the money and time I lost from nest thermostat, I bought a ecobee, and it worked like a charm. I also threw away all my google assistant speakers, apps etc... and went to Alexa. I finally have my house warm without being dictated from a thermostat telling me me what Nest thinks It should be.

While I used to be able to recommend this product to anyone as I have been a user since the first Gen Thermostat....I can no longer do so. Today 05/10/19 an article was posted about the Nest Thermostat becoming fully phased into Google. Nest had privacy settings, a smart hub that could control other smart devices, and a fantastic app....there all going away. But the most important item of all was the Firewall that Nest developers built into the system. That is also being erased. Google will now have access to you data in your home ranging from your location down to the IP address of your wifi Router. https://apple.news/AF9xQOBCfQ7Kw-mfdCqq-Jg this is the article detailing the "Death" of the Nest system. While I can say this is a sad day for me as I have become accustom to using this product it is not the end of the world. Considering I spend a significant amount of money at Best Buy I will try other smart Thermostats and give everyone updates that are needed.

Bought mine before Google bought them out; If I knew that was coming I would not have ever bought this as I do not like my information to be sold for a profit. The device works as expected BUT is not HomeKit compatible. I am going to sell mine to the highest bidder and buying a Honeywell Lyric. Lyric does everything Nest does bit at a much lower price and is HomeKit compatible.

We bought a house with this thermostat installed and thought it a nice bonus. That changed pretty quickly. We have pets and so want to maintain a constant temperature in the house. Nest makes this impossible. I have turned off home/away assist and schedule learning yet in the winter we will wake up in the middle of the night cold and have to go turn the thermostat back up. It does the opposite in the summer. It keeps turning the air colder than what we set it at. I will set it to cool to 75 and 3 hours later walk by and it has set itself to cool to 73. We have even password locked it to make sure no one is changing it or brushing against it in the hallway and causing it to change. The most basic thing a thermostat does is maintain a set temperature and this thing just cannot seem to do that. We will be tossing it and replacing it with a normal thermostat that actually works (hopefully).

DO NOT BUY THESE. There's a defect and right after your 2 year warranty has expired, the unit will be unable to connect to your Wi-Fi. If you don't believe me, Google it. If this happens before your 2 year warranty has expired, it seems Google will work with you, but good luck in trying to find someone at Google.

It’s battery always runs out so it’s “offline”. Its schedule is difficult to set and it’s always adding heat times that I don’t want -and increase my bill. “Clunky” is an understatement when describing the on-unit interface. If you must do anything besides change the current temperature, using the app is a necessity which shouldn’t be an issue for a device that costs $300. Pretty round glass tho. (ecobee has a great touchscreen) It’s a stupid design to allow this thing to run without a C-Wire, it has a battery, but it frequently runs out, and it forces the furnace to run off-schedule to charge itself. The upstairs bedroom is usually at least 10° warmer than the ground level, where the nest is mounted. Additional room temperature sensors (like the ecobee), and running the fan more would be a benefit. Oh, and the ecobee works with Siri. Buy an ecobee.

I had two working thermostats in my home. I replaced them both because I wanted smart thermostats. One Nest works fine and the other has been a disaster. Sporadically it shows that my home is heating but no hot air is coming out. Google Nest support has been a disaster. After multiple phone calls and tests they have me perform to isolate the problem it is still not fixed. I've paid to have HVAC people come out and they say the problem is the thermostat. Google wants me to keep exerimenting to solve the problem - they won't send a new unit. I've wasted 10 hours of my dealing with their support and mulitple mornings without heat. I'd never recommend a Google Nest to anyone.

I will be getting rid of my nest because after about a year it's failing. It was supposed to make life easier but just the opposite. Now I have to restart and recharge with a USB cable frequently. NOPE!

I purchased the Nest Learning Thermostat from Best Buy and I paid upfront for the installation. 2 days later 2 installers come to my house to installed since I paid $99.00 for installation in addition of the $249.00 for the Nest. The technician ended up scratching wall plate with his screw driver and I did not get any heat for a few days. I did some researched and it seems that they wired incorrectly. I really regret it getting their installation. I called to complaint and they keep you on the phone for 1 hour transfering you from agent to agent. I am starting to hate this company....we had to sleep for a few days without heat.
