    Beware of these "thermostats"....

    • Written by from Gurnee

    I had 2 of these installed for just over a year and a half. Numerous back plate failures and added repair costs forced me to remove these and find an alternative. (Ecobee) My HVAC equipment is the most basic and common- single stage, forced air heat and AC. I do have the notorious "C" wire for powering these units. Since the firmware update in Nov. 2014, they went offline much more often, which defeats the purpose of these when controlling remotely. If you're considering, do extensive research regarding failed FET backplates and the offline issues. $1500 spent for me that I'll never recover. Beware!

    Baseplate FET failures are a real and unresolved issue

    • Written by from Livingston

    This thermostat has a high failure rate. Search for nest FET failures online and you'll find multiple hits. The failure rate is significantly higher than reported and the consequences for these failures are significant (damaged or destroyed hvac equipment and extremely high heating or cooling bills). The FET relays in base plate seem to be temperamental and short out very easily or leak. This is particularly true for the y1 line (air conditioning condenser). The result is that the nest turns on hvac equipment without even knowing its done so. There's no way to find this out remotely. Some people seem to believe installing additional relays may solve the problem. I lost a condenser on our vacation home to the nest and my electrical bills were never higher than when I had the nest. I am sticking to thermostats from established companies that know how to handle power surges, leaks and other issues that are common in hvac systems. I've lost enough money already and don't want to experiment any more.

    Guess what?? It's offline again.

    • Written by from Riverside

    We have two of these thermostats in our home. They take turns each day going offline. When you physically go into the settings of the offline thermostat, it shows it's connected to the wifi network with full signal. The eight Nest Protects we have never have an issue with wifi connectivity.

    Offline Daily

    • Written by from SAN PEDRO

    My Gen 1 Nest worked like a champ. My Gen 2 Nest is offline more than it's online. It's at the point that the only reliable way to control it is manually. The pretty much negates the reason for owning it. Nest customer service is polite, in fact I've never felt better while being blamed for a problem. My Nest Protect seems to work just fine so it can't be my wireless network, a fact that seems beyond the comprehension of the tech reps I've spoken to.

    Definitely looking into alternatives at this point. I'm rating it two stars only because it looks neat.

    Keeps going off line in both homes

    • Written by from Hudson

    Have a Next Thermostat in two homes and both keep going offline. Someone has to be at the thermostat to get a reconnect code so this is not really a remote Thermostat. Over $500 shot.

    This thing use to WORK

    • Written by from Townsend

    This product was great 2 years ago and all of the sudden in October 2014 it stopped working. It would go off-line and I would be unable to control the temperature in the home. The customer support was great but they never help me fix the problem. I'm sorry to say I got rid of my nest

    Avoid At All Costs!

    • Written by from LEAWOOD

    I am constantly having thermostat going offline with my 2 Nests. It didn't start until the last software update. Been using the same Airport Extreme both before and after the SW update. Nest is taking way too long to get this fixed. This makes the iPhone app useless since it can't talk to the Nest. Also, no HomeKit or Geofencing support. Once a great product now marginalized. I wish Apple would have bought Nest instead.

    Was great. then disaster.

    • Written by from Philadelphia

    Have had Nest installed for over a year. Some wifi connectivity issues, but temp never fell below my preset minimum temp. We just got back to Philly from a two week vacation. We connected to the best when we landed and took off the AWAY setting and set Nest to 70. Get home in two hours and the house was at 41 degrees. Assumed it was the furnace and called for emergency heater repair. Tech proved out that it was the Nest, not the furnace. $280, one new Honeywell thermostat and 10 minutes later heat was back on. Nest log shied activity until 2 days before our return. Luckily, with Philly's high-teens weather it failed during a warm spell and we avoided frozen pipes.
    This has got to be a no-fail product. I'm thinking I bought into the IoT hype too fast. BE VERY AWARE!!

    Always going OFFLINE

    • Written by from HOLLAND

    I would rate this stat a 4 star if it was not going OFFLINE all the time.

    I have 8 of the Nest thermostats. They worked fine for the 1st year and a half. Then after a firmware update to 4.3.3 , sometime in November 2014, they all went intermittently OFFLINE. Typically not all at the same time. I've had as many as 6 at the same time being this way. I got with support, which took a while to get to an engineering level person, and after going thru some stuff with my network they admit that there is a problem with their firmware but as of yet no update was released.
    This was about 5 weeks ago.

    I really like the stat. It seems to regulate fine but the problem is using an app or computer browser that it shows the stats OFFLINE and can't communicate with it. It might be in this state for 5 minutes or 25 minutes. Eventually it comes back ONLINE.

    I'm in a holding pattern now but if not fixed soon I'll go to another brand thermostat.

    I have had this thermostat for over one year. Nest has replaced it once but still a problem going offline. Every wi-fi device I have stays on line but the nest stays off line a good part of the time. it is a real problem when I am out of town and need to turn it on when I get home.. I would shop around !

    Great Solid Product

    • Written by from Plymouth

    Been using the Nest thermostat and Nest Protect's for a few years and no huge complaints. I've never had any significant issues with the thermostat except for a few software issues that were quickly remedied by updates. Im not sure what issues the other reviewers have had with significant temp drops, since its set up with auto temps and a safety feature that will turn the heat on if it gets under a certain temp. I had the 'Offline' issue but that was fixed with some network troubleshooting. I can definitely see how it saves me money on oil as we've used much less oil in the past two years having the Nest. My only complaint is the difficulty getting support on their website. Since theres no live support or email support, you have to call them, which when I work during the day of their support hours, It can make it difficult. But as far as the hardware itself, its fantastic. Has more than paid for itself.

    Holy smokes what is with this product?

    • Written by from Sherwood Park

    we bought this thermostat to save a bit of energy but come on! You can't control the temperature, it seems to do its own thing and won't let you override it. I woke up to a house in Canada in the dead of winter at 16 Celsius! My dog was about ready to pack his bags and leave it was so cold! Listen in theory this product is amazing but it's not a good product, I'd worry leaving this guy on when I was on holidays! It randomly turns my furnace on and off and it's not efficient in the least. Stay away until they work out the bugs!

    Not so smart afterall

    • Written by from Athy

    Will keep this short -

    Despite having two units replaced and testing with 8 (yes 8) routers these thermostats hate to stay online. They constantly loose their connection to WiFi and cannot be controlled remotely.

    NEST support state that its a known issue etc etc but no fix.

    Advise. Dont buy

    Looks awesome. Worked Great for 3 months. Then Epic Failure.

    • Written by from Arlington Heights

    After 3 months of impressive performance, my family went away on a three day vacation. On the way back and about an hour away from returning home, we tried to turn the heat up so we could arrive to a warm home. The setting was on "away." When we tried to turn the heat up, we got a message saying that the last time the unit was "on line" was two days ago. We were disappointed that we could not warm up the house but that was the least our problems. After assuring my wife that the Nest would just maintain the preset "Away" temperature, we were shocked to arrive at a house that was 43 degrees F ! The weekend had been cold. It never got above 20 degrees and the over night temperatures were in the single digits...I have a separate thermometer in the house that records low and hi temps as well as the current temp and I confirmed the house had gotten as cold as 34 degrees! Half of our houseplants looked dead and our upstairs bathroom had frozen pipes! Nest support was responsive once the 20 minute wait to get to a live person was experienced. After several trouble shooting recommendations, we were able to get our heat working by tricking the Nest into believing the AC was the heat source. So the problem was our base. Nest promised to send us a new one immediately but seriously, this product, while nearly there in terms of functionality, design, and ease of use; is not ready for prime time. A device this importance needs redundancy protections built in. IT CANNOT change settings preset by the owner. END OF STORY. No excuses please. Make a device more reliable, not less reliable, that the unit being replaced. It took more than 12 hours to heat our home back to a normal temperature. Imagine if we had been gone for a week or more???? This was a horrible experience I don't wish on anyone. I reinstalled the old thermostat. Bummer but at least it works.

    Do NOT buy!

    • Written by from Washington

    Thermostat worked fine for about a year, then disaster. It started turning the heating on and off repeatedly. All attempts to troubleshoot through the web site were useless and eventually escalated into a trouble report submission. Their support process is really broken. You must deal with an especially annoying voice menu which, of course, puts you on terminal hold.
    Save your money and stick with an "old fashioned" thermostat -- having given up on Nest/Google I'm reinstalling my ancient Honeywell (which actually is dependable, unlike Nest).

    Big Brother has Control of your THermostat

    • Written by from Holyoke

    I hope you correctly interpret the one star above as a negative assessment. I was forced to click on at least one start before I coudl submit my review. Too bad we could not depict negative stars.
    The NEST product was an interesting and fun gadget for a year and a half ... until control of it was taken away by someone during one of the coldest days of the year. As the house got colder and colder I worked through the NEST website looking for tech support to no avail. Finally Googling "NEST help" got me a contact number. During three hours of troubleshooting I found out that this thermostat was part of an energy savings program. NEST thought the thermostat was controlled by my local utility. I contract my local utility and they had no idea what I was talking about. I then went back to NEST and they still had no idea who was controlling the thermostat or how low the "Controller" whoever that was would let the temp fall. I worked with them a little longer in an attempt to opt out of this energy saving program and after three hours I told them thank you very much, but your time is up. I then replaced this thermostat with a conventional programmable thermostat. The NEST product is not ready for prime time.

    Simply Horrible

    • Written by from Greenwich

    I have been using eight Nest thermostats in my vacation home for quite awhile. They worked great when first installed. Then Google takes them over and the product is a brick. Goes offline constantly. Simply unacceptable. I use numerous Ecobee3 thermostats in my primary residence. They work flawlessly. Although a major economic hit, I am switching all my Nests to Ecobee3s.

    Over priced and frustrating

    • Written by from TAMPA

    I have had a nest thermostat for over a year. While it was easy to set up initially I feel this thermostat has given me more frustration than convenience. From day one the mechanism has never turned fluidly, seated properly against the base, or clicked properly when pressed but I could overlook all of these issues if it weren't for so many other shortcomings.

    As others have mentioned there is no temperature hold button to override the auto schedule… This is particularly frustrating when you are home on vacation and have to continually readjust the thermostat after the schedule has changed it.

    One of the more shocking design flaws of this thermostat is that the act of touching it alters it's temperature reading. There is a MAJOR design issue where touching the outside ring and turning the selector affects the temperature sensor causing the indicated temperature to increase beyond the actual ambient temperature. FAIL

    Another prevalent issue has been that the thermostat will lose connection (go offline) and be unreachable from a mobile device. This is particularly frustrating when you combine it with the above design flaw of touching the thermostat, LOL.

    In closing, I cannot recommend that anyone purchase this thermostat considering the cost and poor design quality. It simply has too many design issues to be a true competitor in this market.

    Worst Thermostat EVER!

    • Written by from BUFFALO

    I can't even begin to say how upset I am to have to title the Nest Learning Thermostat as "The Worst Thermostat EVER." For the "cool" factor and appearance it was in "A" in my book. I installed it in November 2014 and it worked like a charm... for 4 weeks. The we came home to a house that was 80+ degrees in winter (in Buffalo no less) and found "the base unit was malfunctioning" preventing the nest from shutting off. The "overnight" Fed-Ex replacement arrived in 2 days which meant I had to manually turn on and off the furnace from the circuit breaker. The new nest worked great... for 3 weeks before it did the same thing. Another call to nest with their crazy long wait customer service stated this was a known issue and another unit would be sent... "overnight." Four (4) days later FedEx showed with my third unit in the same number of months and it worked again...well. Yesterday, after only 2 1/2 weeks from install, the Nest again malfunctioned and my phone call to their customer support agent and "senior" agent finally concluded my energy effecient Heil forced air gas furnace was "incompatable" to the nest. What?!?!? I have finally had it and went straight to Home Depot and purchased a Honeywell "Smart Thermostat as a replacement. My last honeywell thermostat lasted over 20 years and I'm just hopeful this one will last longer then the Nest's.

    So...divert your eyes from the aestetic appeal of the Nest Thermostat and purchase another brand. Maybe in the future the Nest will be viable, but until that day you owe it to your home to find another thermostat.
