    Very pleased

    • Written by from Live Oak

    Before buying, I used Nest's website to confirm if my thermostat hookups were compatible. An easy, but incredibly important step.
    The installation was simple, but I took my time since I wanted everything to be perfect.

    A negative surprise: It may've been my router (Motorola Surfboard SBG6580), but I found I had to Broadcast my SSID (router name). Most people have this broadcasting all the time, but I prefer to not do so. Nest would not connect for me unless I set the router to the default (allow broadcasting).

    Note: I didn't call Nest to confirm, but I could've.

    Once that change was made, everything connected and setup was smooth as silk. The UI is incredible in my opinion, and I also took the time to learn more about my house (had just bought this house) when I received prompts that I was unfamiliar with (like whether I had 2-stage heating). Nest's site helped with this also, but I still had to do some research on my own, which was not a problem.

    Since then, our AC is running much less often and somehow the house is incredibly more cool. For the first time in my life, I am comfortable with 80°… I usually kept it at 75° in this house with the old Thermostat and in previous houses. I honestly don't understand what all Nest does differently, but I am surprisingly more comfortable at these higher temps now… with is a great feeling when the weather outside is usually 100° or above this time of year.

    So even though I still do wish Nest could find my wifi without the Broadcasting option turned on, the benefit FAR outweighs the single edge-case drawback that I mentioned.

    Also, I want you to hear this: I ALMOST didn't order the Nest due to the negative feedback some posters were leaving here on this site. I eventually ran across another review that more or less discredited a huge number of 1-star posts by explaining the reason for their complaints (he was an HVAC tech, he explained, and his post was technical and well written - boiled down to these 1-star raters not having compatible systems, which would've been detected simply by following the guide on Nest's site). So I went for it and am so very glad I did.

    Not worth the money

    • Written by from Sandy Springs

    First - Nest lacks the most basic of thermostat functions: Hold Temp. Enthusiasts will tell you the Nest features eliminate the need for it, but Friday was a holiday and there was no way to tell the thing not to run the usual weekday program.

    Second - Auto Schedule makes random unexpected changes. The ability to confirm those changes would be great. My thermostat decided that I didn't want the temp to drop to 70 degrees at 10 PM anymore and cleared that part of the program even though if I made that adjustment, I only did it once. So Auto Schedule is off.

    Third - Auto Away overrides the schedule. So rather than having a comfortable temp in the house when I get home from work, like the program is set for, the thermostat goes to Away when I am at work and I have to interact with it to get it to run the program. What is the point of a schedule if the thermostat doesn't follow it? So Auto Away is off.

    The novelty features of Nest don't really work. I'm pretty sure that the thermostat is not smarter than I am, but it thinks it is and does things it thinks I want. I shouldn't have to interact with my thermostat regularly to get it to do what I want it to, but that is what the Nest requires.

    There are less expensive wifi connected thermostats that do what the Nest does. They don't have the fancy metal ring around them, but that is about all you are getting for the extra money. I wouldn't buy another one.

    Nest 2nd Gen Thermostat

    • Written by from Cary

    I recently upgraded my upstairs and downstairs HVAC units. I also installed 2 Nest thermostats. The devices are truly amazing. Rather than adapt to some old paradigm of programming a device these devices adapt and learn from your habits and schedule. In a few days I could not imagine going back to a conventional programmable thermostat. Easy to install and get running. It may be more difficult for me to determine energy savings since I replaced my HVAC units. But having a device adapt to you rather than you adapt to it is great. Revolutionary just as the iPhone was. Highly recommended.

    This is a hot product that is totally cool...

    • Written by from Van Nuys

    I was amazed at the thought and expense that went into the packaging of this product, even a fancy screwdriver set with interchangeable heads. It almost looks like an Apple product.
    The installation was dead easy, complete with colored stickers you wrap around the original wall wires so you don't get confused.
    The unit worked straight away after I figured out how the programing works.
    Looks great, works well, and we have no issues with it.
    Highly recommended.

    Recommended!

    • Written by from Annapolis

    This is a huge improvement over all traditional or programmable thermostats. The ability to remotely access and command it is reason enough to own one or more, if you have multiple zones, as you can command or manage them from a single location, even after you've gone to bed. It's ability to sense when you have left the premises means you'll never again heat or cool an empty house because you forgot to set it before leaving. You'll get useful reports of your most recent 10 days of energy use, and will wish it was at least a full month to compare with your utility bill. It's relatively simple to install and set up initially, but has enough depth of options to satisfy your "control freak" tendencies. When auxiliary heat is needed, it isn't smart enough to keep the heat pump running continuously, but is otherwise pretty with it. Since it is online and can be continuously updated with new software, it should get even better with time.

    Monitored My Home From 1,800 Miles Away

    • Written by from Carman

    Spent the winter in Arizona and monitored my home's temperature in Carman, MB via iPhone, iPad and a PC. Great! Still can't believe they haven't built in a notice system that would send an email if furnace fails to start on demand and temperature drops. Given that one's login credentials include the email address, it seems like the infrastructure is all there. Someone just needs to activate it.

    Motherboard Chatter Causes Problems

    • Written by from Calgary

    We own a three-year-old York furnace. I installed the Nest thermostat before winter. Throughout the winter we had several problems with the furnace – we had to replace the motherboard twice, fan and other repairs. The technician finally diagnosed that the Nest kept making calls to the furnace turning it on and off (chatter). We have since replaced the Nest with a regular thermostat and have experienced no problems. This was a very expensive experiment. Cool product, but does not appear to be ready for mainstream …

    Happy and surprised

    • Written by from Lakewood Ranch

    I have to say, pleasantly surprised all the way around.. easy install, has performed over the past 6 month (almost) flawlessly. I say almost, only because it dropped wifi i think 1 time... but seriously, I couldn't be happier... You will enjoy, without doubt!

    Frozen Pipes

    • Written by from Zhangjiagang

    Before starting this review, let me state my credentials. I am a Physics Ph. D, with over 20 years experience in test and measurement, and I also have an electrical engineering degree, dozens of technical publications on testing and simulation algorithms, in addition to law school and being CTO of a tech company. If I have trouble getting this device to be reliable, I'm going to make the claim the device is not reliable.

    I used a Nest thermostat for about 4 months before it failed, causing the pipes in my home to freeze and rupture. The issue is apparently related to the inability of the battery to remain charged when the weather is cold and the thermostat needs to signal the heat to run for long periods of time. There is no fail safe mechanism built into the thermostat makes the device function in a safety mode when the controller dies from the dead battery. I bought a gen II device with some version 3.5 something of the ROM. It had upgraded to version 4.0.1 without my consent when problems began to happen. I was away traveling one day when I noticed the battery was creeping downwards, and there was absolutely nothing I could do remotely to turn the heat on. It eventually went offline for a few days, and then magically reappeared a week later, running the heat for 48 hours to heat the home to the scheduled temperature. What was interesting to me before the failure was in spite of the fact the battery had enough charge, I still could not get the Nest to turn on the heat. After a day the battery died, and I lost contact. I was fortunate to have turned off the water at the home before leaving, but of course it is always impossible to drain the water meter, and the meter froze and ruptured. When the heat resumed by itself without me being there, the basement became wet. Very scary!

    My opinion is this s a great concept, but rushed execution resulting in a device that is not tested in all possible real world situations. It is not a good thermostat to use in environments where it is either so cold or so hot that failure is not acceptable. If you have winters where the temperature falls in the -20 C or cooler range for extended periods of time, do not use a Nest. Buy something with 120 years of proven reliability, like an electromechanical round Honeywell thermostat. It will save you a lot of headaches and cash. If you want to monitor your home temperature remotely, learn to use an arduino and temperature sensors. It will be safer.

    I think Nest ought to start worrying about a class action. I have heard several similar complaints. They might consider proactively addressing this problem.

    Not as good

    • Written by from Dearborn Heights

    I purchased Nest, after couple month of on and off working out the way it works, it was working fine, until and in a cold night of January, the house was very cold, come to find out that the thermostat is completely dead and without any warning, lucky enough I have kept my old thermostat, I changed the thermostat back to the old one. after checking the Nest thermostat, the battery was completely drained, and needed to be charged.
    if it works like it should, its a good thermostat, but when the problem is in the source of this thermostat, lots of glitches needed to be workout.
    I don't advice anyone to purchase this thermostat, and if you do, keep your old one handy because you going to need it.

    Use Your MAIN WiFi Account

    • Written by from Surrey

    I have been using the NEST 2nd Gen Thermostat for over 10 months now and LOVE IT! It "learns" and can be "programmed" to a set schedule if you want. I have mine set to start warming things up 30 min before my alarm goes off, nice to wake up to a warm house.

    Wi-Fi Heads Up:
    I changed my home Wi-Fi to the new Apple Time Capsule (Tower) about 3 months ago and a little issue showed up.

    When I got the new Time Capsule I set up a "guest" wi-fi account and used that for the NEST, this did not work well. After a while the NEST stopped communicating on-line, turns out the security Apple builds in for a "guest" wi-fi account is actually pretty good and that interfered with the ability for the NEST to do it's thing over an extended period of time. I simply set the NEST up on my MASTER wi-fi account and it has not skipped a beat since (over 2 months now on the new account). Working PERFECT!!

    Being able to control from the app is awesome! If you travel, about an hour before getting home simply switch it to "home" from "auto away" and when you walk in, temp will be perfect!

    Enjoy!

    Perfect Implementation, Perfect Product

    • Written by from Concord

    I recently installed two Nests. I had held off because I was concerned about what I was getting into. Now I am kicking myself for holding off. First, Nest comes with pretty much everything you need (right down to a screwdriver). They even supply little labels for the wires, so that once you remove the old thermostat you will not be confused about which wire goes where. Another nice touch, they supply a backing plate in case the previous thermostat was larger and the wall is in less than perfect condition.

    Install time --> This literally took under 15 minutes. From start to finish. Not an issue at all.

    Using the Nest is a breeze. If you are not technically minded, then you just turn it right to increase the temperature and turn it left to decrease. That's it. That's all you have to do.

    However, if you are technically minded, the Nest will (quite easily, actually) connect to your wireless network. Once connected you can change your temperature settings from anywhere. Leaving on a trip and forgot to set the thermostat accordingly? No problem (more on this later... Auto Away... Awesome). Getting ready to leave the office and you want to make sure the house is the proper temperature when you get home? Piece of cake. My personal favorite: Feeling a little cold while watching TV, but REALLY don't want to get up to fix it? Not an issue, just pick up your smart phone and turn it up a degree or two.

    Humidity control, power saving features like running the fan when heat or AC isn't necessary, polling the predicted weather over the internet to make decisions about how to best cool the house, sun blocker technology so the unit will not freeze you out just because your builder was an idiot and put the thermostat directly in the path of sunlight. These are all things that are built into this product. Finally, Auto-Away. The unit detects when you are away and automatically switches into Away mode, where it will keep the temperature from getting too high or too low, but won't run unless it absolutely needs to. Saving you money. Live in a hot and humid area? It will even adjust the temperature to make sure the humidity doesn't reach the dreaded Mold producing levels.

    This is a perfect product.

    Makes saving energy more interesting and fun.

    • Written by from Thunder Bay

    I replaced my old programmable with the Nest after reading a great deal of positive reviews. They were right, it's just fantastic. I believe it is saving energy. The temperature feels more constant and more comfortable overall. It leaves little to be desired, except a few things. For one, the app that controls it should provide more information and graphs on the main screen. It was easy to program. I would recommend to anyone that can afford one. It is said they pay for themselves in less than two years. Time will tell.

    Simply amazingly... simple!

    • Written by from Rockport

    What's so incredible about the Nest is that it's so easy to install and use. Like first learning to use an Apple product, everything works so smoothly that you feel that you're missing something. At the same time, you wonder why all the other thermostat companies (Honeywell, Johnson, GE, etc etc) have never been able to even come close to this level of efficiency and performance. After the Nest thermostats will never be the same.

    Anyway, I never thought that controlling a furnace could be so fun. With your Nest account and an iPhone app you can control your home climate from anywhere.

    Immediate money saving product

    • Written by from Tinley Park

    As soon as we installed this product in our home, we saw our bill start to drop. It is very easy to configure and schedule and it also learns on its own so if you forget to tell it that you are away at work, it will set itself to away for you.

    Great thermostat

    • Written by from Rockland

    I bought the first Generation and it worked well till they upgaded the software and everything went crazy and I was about to get rid of it because I couldn't find a solution and I notice that most new thermostats require the C wire so I changed the wiring to 5 wire and added the C wire and everything is working great since I made the changes so hopefully this may help other to fix there problems.
    If it wasn't for the problem I had I would of gave it a 5.

    The Nest was my Christmas gift. It would have been easy to install if I wanted to leave it behind a door, but its too good looking to keep it hidden. The Nest work great, easy to adjust and program, and looks great. I really like that I can control the Nest remotely.

    AMAZING!!

    • Written by from Harlan

    I purchased the nest a few months ago and let me tell you that it is the best! In the first week of using nest, it learned my heating/cooling habits and I haven't touched my nest since then. It is really handy when you have to go to work and it will go into "Auto Away". It saves a lot of energy that would've been wasted. Good job nest!
