    It‘s not compatible with baseboard heaters

    • Written by from Montreal

    If you have a baseboard heater forget about nest! We couldn't get any technician to install it here in Canada, nobody wanted to do it and they said that we need to convert our system to 24 volts because Nest is designed for 24 volt systems (furnaces type setups).

    One of my two Nest thermostats has suddenly stopped controlling its furnace

    • Written by from Merrickville

    After two months of apparently working as advertised, one of my two Nest thermostats quit controlling its furnace this evening.

    It was set at 18 Celsius, but the furnace just kept running and running: 19 degrees, 20 degrees, 21 degrees, 22 degrees. I could control the thermostat from my iPad and iPhone, but it did not control the furnace. I turned the thermostat completely off, the furnace still kept running.

    No one answering the phones at a Nest support in the middle of the night.

    So I've turned the furnace completely off. At -2 outside, that's not a great plan, but nothing else to do.

    Love the idea, but product is faulty

    • Written by from Phoenix

    Bottom line - great idea, but they just don't work. After spending $200 for an "Authorized NEST Installer" to install them - the installer told me that they have nothing but trouble with these products and they recommend the equivalent honeywell products instead.

    Here is the whole story if you're interested in the details (I am very technically proficient with HVAC systems):


    Bought three of them. Installation was a breeze, and everything was very well thought out and explained. Then....after about 3 weeks.....the NEST's stated that they needed to be charged! Made no sense to me. They reported a VOC input voltage of 5.03 volts, but I measured 24 volts with my voltmeter. Tech support was WAY LESS knowledgeable than I was about the product, so I gave up. Called an "Authorized NEST installer".....who told me to not bother with the NEST - but I don't like to give up that easily. So we checked everything and installed new transformers on the furnaces, etc. THEN - EVERYTHING WORKED! Until 2 days later when the NEST's reported that there was no power to Rc. The "Authorized NEST installer" sighed and then came over again to install a resistor between C and W......which worked! Until 1 more day when the NESTS again reported no voltage at Rh. Again, I confirmed that there was 24v with no problems.

    NEST tech support was very friendly, but I really get the impression that a lot of people are having similar trouble to what I had. Tech support finally recommended that I return the product for a refund. Interestingly, I could hear a lot of the background conversations while on with tech support - and it sounded as if a lot of people are having similar trouble. In a cold country - you CAN'T have a bad thermostat.....these products probably need to be recalled if they don't come up with an appropriate software update for them.

    This is too bad - wonderful idea with a total miss on application. These NEST thermostats should be a case study in an Engineering textbook on how NOT to deliver a product to the consumer.

    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.

    Fantastic

    • Written by from Leesville

    If it wasn't for the lack of the logo, I'd swear this is an Apple product. It is elegant, thoughtful, and superbly constructed with sturdy materials. The box even has that "new Mac smell," and if you own a Mac, you know what I'm talking about! I've only had it for a week, but so far I'm very impressed. We'll be purchasing another one for our other rooms. The "Father of the iPod" has gone on to do great things!

    Thermostat Disconnected

    • Written by from Eureka

    I purchased a house with 2 Nests. Seemed like a great concept, however the unit's constently disconnect from the App. I'm told it's because they lose power and connectivity is the first function that shuts down. What good is a thermostat that you can control remotely that is only connected 15% of the tiime. Not to mention if you change your schedule for the slightest reason the whole concept of a learning thermostat is in the toilet!. If you work from home Iyou'll need to keep telling the unit that "I'm working in the office, stop setting the system to away!!" The only benefit I have gotten is the abitlity to set the system to away when I'm out of town. That is, if it's connected. Check back enough times and I might catch it connected.

    Stay with traditional Programmables!

    • Written by

    In theory a great thermostat... that is IF YOU are a predictable person / family. As a retired construction / remodeling business owner, including HVAC, I would NEVER put one in a customer's home WITHOUT advising them of the potential problems with this "engineering marvel". AGAIN, IF you have a VERY regular AND predictable lifestyle, maybe an OK choice, but at the retail price (what the homeowner is charged by most contractors), I'd NOT recommend it! PERIOD! My business operated / grew on by-name-referral BECAUSE the products I installed were top-notch as was our craftsmanship -- "Old Worlde". W e did NOT do bandaid fixes NOR install junk! This item may not be junk, BUT it'll have you wanting to rip it off the wall and throw it out the window or in the fireplace... when you wake up at 3 AM sweating because the STUPID thing has decided no one is home! OR, you'll come home having set it back BEFORE you left for the week... only to come back to find it "had a mind of its own" AND turned the house into a meat locker when no one was home!!! Neither of my HVAC systems have one!!!! As I said, in theory (and design) may be an OK idea, BUT has far too many shortcomings -- PROBLEMS -- to be used in my high-end business. AND by "high-end", I mean QUALITY, NOT ridiculously expensive!!!! Stay with traditional Programmables! They're more dependable & trustworthy, like the KC-135s I flew, that are still in the air, while KC-10s may soon be history (retired USAF)

    Gorgeous design & impressively engineered. Buy it!

    • Written by from Nashua

    A beautiful, beautiful, piece that will turn heads and turn down your electric bill, this well thought out thermostat is an architectural element that will literally pay for itself over time. (And you can adjust the temp without getting out of bed!) Honestly, I would've bought it just for the design, but Nest did it right, and made it better than all of the rest for the number crunchers concerned with a return on their investment too.

    HAL 9000

    • Written by from Moreno Valley

    HAL 9000 is what I named my Nest. This is one of the coolest things that I have ever bought. My old thermostat would always turn off and on at different times, yet it was not broken. When I installed it—the old unit—I set up a schedule. Yet 2 years later it seemed like it either never went by the schedule or just ignored it all together. Like many people, my energy savings went out of the door. I replaced it with the Nest—read Hal 9000—this thing is unbelievable! First off, they have thought of everything. The install, they have plates that cover up your old thermostat's hole... they include a screwdriver to disconnect the leads/wires from the old setup... they even have a leveler with the green fluid and bubble built into the unit so you know it is level. After the install be prepared to be amazed. This thing has wifi, learns your habits, you can operate from your phone or computer—it even senses when you are standing infront of it! This things is like strapping an iPhone/ipod/ipad to your heating and cooling system. Hal 9000- I mean the Nest is amazing! The only problem that I am having is explaining to my friends that they need to come over to my house to check out my killer thermostat. They think its weird until they see it, and then they want one. Only thing left to do now is teach it to open the pod bay doors, and then tell it to refuse to open them after I ask.

    Excellent

    • Written by from Innisfil

    I have had this for over three months now, and I am truly amazed with it.
    I like the fact that if I go away for a few days, I don't have to worry about setting up a new schedule, it knows I am away and takes care of everything.

    On my way home form a weekend of fishing, I can turn on the air conditioning before I get home, so the house is cool by the time I get there.

    I really like not having to switch the thermostat from heat to cool, it just knows what to do.

    A fantastic device. I think it is overpriced, but I still bought one and I am very happy with it.

    Best Thermostat you can buy

    • Written by from Spokane

    My wife pre-ordered me one of these when they first came out a couple of years back - and I love it. Nest has updated both the iOS software and the software running the unit itself many times with new features and enhancements and they've all worked perfectly. It's interesting to review the history it keeps and learn how often your furnace or AC kicks on in different weather conditions. Over the years, I've turned it into a game of how much I can save by either letting it work itself, or even for example actively cooling the house at night. When we are away on vacation, it's even piece of mind to know that nobody came into your house (and that it's still standing!). I actively turn it on when I'm an hour or so away from home so that the house is up to temperature when we get home. I bet that becomes a feature with future software updates. No doubt the most used iOS App on my iPhone. Check them out at Lowes if you're unsure - but you won't regret buying this thing!

    It took me 10-15 min to set it up. Works great and I like the look of the device. I just got it so I am still experimenting with it but its got lots of options. I'm looking forward to playing with it and enjoying the benefits.

    Amazing is an understatement

    • Written by from Fresno

    Sooo I bought two of these jewels for my home. Setup was a snap. I had them both working in less time than it took for the software to update. The energy reporting day over day is really helpful. The remote access is great fun. We were out of town for the weekend. We set the temp to 80 and cut the usage for one unit to 0 hours compared to 6 hours and the other to about 6 hours instead of 11 hours (two story house). When we left for home we set them back to 77 and when we walked in the door the entire house was cool and comfortable. I am very anxious to see what kind of energy savings we will enjoy now that we can really monitor our usage. Only criticism, is I wish the daily energy usage could also be viewed real time every six hours day over day.

    Awesome Thermostat!

    • Written by from Conshohocken

    Works great. iPhone 4S app is amazing. Very intuitive. Looks great. "Away" feature allows you to use the A/C or heating less and save $$$. Really nice to be able to go away on vacation and turn it on remotely before you get home.

    And great customer service. I thought I had a hardware issue that likely was software related but support helped me out over a couple phone calls. Even sent me replacement parts and a charging cable all free of charge. Highly recommend.

    I never thought a thermostat could upgrade a room. I know my old white one that was stuck on 74 degrees wasn't very pretty. My new lovely Nest thermostat is gorgeous! And it almost feels like my AC works better now. This is one of the coolest gadgets I have ever bought. I think I might like it more than my iPad or iPhone....well, at least I equally love them all.

    Love It!

    • Written by from Bethesda

    I've had the nest for a little over a month. I have yet to see another power bill to compare savings, but intuitively, I know I have saved money.

    The installation is easy. Just take a picture of your current thermostat's wiring, use the Nest website to determine if your system is compatible, and then its as simple as taking the old unit off and reconnecting the new one with maybe a few holes needing to be drilled. Programming the unit was relatively easy too. Once I manually entered the wifi password, just about everything else I could do from my laptop.

    Once you set up the system, it does learn your habits, but it also has settings to keep various temperatures during the day and an away feature that can be set. The way I see it, you have redundant options to keep your house comfortable without wasting power.

    One feature I love is the iPhone app. I can monitor the house temperature throughout the day. I often use this feature when I am leaving work to ensure that the house is comfortable by the time I arrive home.
