    I was skeptical

    • Written by from Holly Ridge

    I recently purchased my first home and the first thing that I noticed was an incomprehensible programmable thermostat. The instructions were provided, but the thing requires an advanced degree of technical expertise in order to operate it... oh and it was beige and ugly. When I did use it, I would change the temperature manually but even then it would 'forget' after a day or two and return the temp to some hidden factory setting stored in its memory.

    Being a gadget-geek, I was browsing the Apple store for one of my wife's christmas gifts (an iPad mini which she has yet to put down... the diamond tennis bracelet however is still in the box. I love my wife!) I noticed the nest and made an impulse buy mostly for the elegance of it's design and implied ease of use. Upon installation, I was not disappointed. I did my own installation. As other owners have mentioned, the Nest is MUCH smaller than a typical programmable thermostat. I for one broke out the plaster, sandpaper, and touch up paint... I like things that are simple and intuitive. You can use one of the enclosed backing panels, but it simply will not be as clean and streamlined.

    I love the iPhone and iPad apps, which allow me to create a manual schedule - a constant 68 degrees. And when you set it at 68, that is where it stays. That doesn't sound like much, but it was a new experience for me... a much appreciated one.

    The only issue I had was connecting it to my Airport Extreme. I maintained a hidden network, and Nest simply could not maintain a connection... after calling customer support (who are amazing) I decided to unhide my network and it worked without issue.

    Nest

    • Written by from Dollard Des Ormeaux

    This product is amazing! You can control your thermostat from wherever you are whenever you are. Don't worry if you've been gone for 2 weeks and you think all the air conditioning has gone to waste and will cost you a ton of money because with the Nest you can put it to a certain setting so that it will save you energy and money.

    The Nest - Problem after problem

    • Written by from Wayne

    The Nest upgrade to v 3.5.1 (7.1.13) software has created massive connectivity issues (failures) for me (Apple Routers) and others. See Nest community form. Very disappointing product.

    Once its properly installed it is great.

    • Written by from Maple Ridge

    I had a two wire thermostat, gas fired furnace installation.
    While the instructions state that this type of installation is straight forward and will work, it quickly became apparent that this is not the case.
    The unit has an internal re-chargeable battery that charges itself while the heating circuit is closed and the furnace is running when in used a two-wire thermostat system. The problem with this is that the heating system may not be active for a long enough time to fully charge this battery.
    This was the case in our installation and it was not long (about 10 hours after installation) before the battery was discharged to the point where the Nest would not function.
    To ensure that the battery does charge on a regular basis I ran a third wire from the thermostat to the furnace and connected this to the continuous low-voltage supply at the furnace thermostat wiring panel. This wire is referred to as a "C" wire and the "C" terminal on our furnace wiring panel was clearly marked with a "C" making it easy to complete this installation on my own. Having done this I have had no problems with the unit and it works exactly as promised in all of the literature.
    The "self learning" function works great and the ability to activate and control the Nest from wherever I have an internet connection and my iPhone or iPad is outstanding.
    We have been using the Nest for over one month now, during a particularly cold period, and can already see a difference in our overall power consumption. While this may be due to any number of other factors I feel that this product has contributed.

    Nice Idea but Bad Product

    • Written by from Hopkinton

    Same as the previous review I woke up one morning during the recent cold snap to the downstairs (where the Nest T-stat was located) being in the 40's and found that the Nest thermostat had stopped communicating with my furnace. To be clear both other zones in my house were working so it was clearly a problem with the Nest. After disconnecting it and rechecking the wiring (which was fine) the unit was reinstalled and it worked again. Two nights later the same thing happened again. After a quick internet search I found that this a problem with the Nest on some types of HVAC systems. Once I installed the old (non-Nest) thermostat everything worked as it should. Do yourself a favor and stay away from this product.

    Poorly Engineered Product

    • Written by from Mississauga

    As previous posters found out with hefty install bills from HVAC techs, being electronic / electrical literate I decided to do the install myself. If you are not colour blind and can meter voltage at wiring it should be a no brainer to troubleshoot or transfer wires off an existing thermostat right? Wrong. These things indeed have baseplate resistance or bad terminals on them, the firmware is not up to recognizing that either - I went through 3 and about 8hrs of troubleshooting, ended up running completely new thermostat wiring from the furnace controller just to rule out any resistance off the old wiring. In the end I think that did the trick, these things require clean 24V at RC / Y1 / Common or forget about it. And of course each time I put the old thermo back in on the old wiring, it worked! But I could never get the thing out of these E30 errors, either no power to Rc or Y1. Who knows, 3rd product was the charm I guess and new wiring (18 gauge). My local Home Depot gets more back than they say stay out. However, thumbs up to the software, they got that down right. I should also say I put in 2 Nest Protect C02 units, both function perfectly.

    Nest Issues--New Paperweight

    • Written by from Phoenix

    I bought my Nest approximately 8 months ago. It worked perfectly until 2 nights ago. It then started turning on the heat and cooling at the same time. My a/c-heat technician says the baseplate shorted out and now won't work. Crazy money for such an imperfect and short-lived product. I gave it 2 stars solely because I like the visual design so much--otherwise, it is a waste of dough.

    Total POS

    • Written by from Alton

    These things are horrible. I have spent hundreds of dollars on HVAC repairs that always end up being the mystery "low battery" phenomenon. I am about to remove all 6 units and replace with Honeywell stats. Oh, they are very pretty but that is all they are.

    Too much trouble - energy cost increased.

    • Written by from Loveland

    First off, I'm very tech savvy, over 20 years in electronics design and software engineering, so I'm capable of following basic installation instructions. I was quite interested in the Nest thermostat. My house is heated and cooled by a newer heat pump. I dutifully took a digital photo of the connections to my old thermostat and sent them to Nest. When i called, I was assured that the 2nd generation thermostat would work fine with my system. Nest even sent me an email with wiring instructions. This would be a snap, I thought.

    All seemed fine at first. Then, during a twice-yearly HVAC service, the tech asked me why I had the emergency heat on all the time the unit was running. I was puzzled. He showed me that it was indeed running on emergency heat. After a couple of calls to Nest tech support, I gave up, reinstalled the original thermostat, and returned the Nest for a refund. Then - insult to injury - I received an electric bill that was nearly 3x normal - emergency heat is expensive! I could have bought 2 more Nests with the additional energy cost. By the way I checked, double checked, and confirmed with Nest support that everything was wired and configured correctly.

    Not a happy outcome.

    Nest is Junk

    • Written by from Minnetonka

    Woke up one morning freezing and found that the Nest "learning" thermostat had stopped communicating with my furnace. Tried to turn the heat up and received a low battery message. Called support and they assured me that after charging the thing with a phone charger that it would work again. Temps went to -15 in MN and I woke to a temp of 49 degrees inside my house. Called customer service again and spent over an hour trying to correct issue until they decided it was time to send me a warranty replacement. It took over 3 days for this to arrive and the customer service rep told me that I should go to the hardware store and purchase a traditional thermostat if I hadn't saved my old one to keep my pipes from freezing in my home! Warranty replacement still does not work, I've spent way more on electric bills to run space heaters while the furnace was out, missed a day of work to install emergency thermostat so my pipes wouldn't freeze, I have an 11 year old son who couldn't sleep on a school night because it was bitterly cold in our house, spent hours on the phone with nest "technicians" . Do yourself a favor and buy a normal thermostat, I wish I would have.

    Does not work in cold weather

    • Written by from Hanover

    I have had HVAC technician talk twice with NEST to get it to operate correctly. In single digit weather the system would only blow cold air. Change system back to Honeywell thermostat and house is warm. Also, does not work with changeable fan speed system. I gave it a year to learn but to no avail.

    Really wanted these to work

    • Written by from Tipton

    For what it's worth, I'm a software engineer actively working in the "connected devices" world. Point being, I SHOULD have above average technical know-how.

    Summary of installation for TWO thermostats:
    Wiring 20 minutes total - easy
    WiFi config - 40 minutes (really painful - no exaggeration) AND I had to change my router security to mixed mode before it work. I have a 3 year old Cisco router. I've had no problems with any other device in my house and I have probably 12+ "things" connected all of the time.

    Next morning
    - Error displayed on the Nest and my upstairs was at 61 degrees.
    - Nest support ran through some tests and determined my furnace had an issue and I should call my HVAC guy.
    - Just google "N26 No power to G wire detected."
    - This furnace is a heat pump and apparently didn't provide enough power to keep the Nest happy. I replaced my old thermostat and everything was just fine.

    During the next week
    - My Gas force air furnace worked great and the info coming off of the Nest was exactly what I had wanted/expected. ...until it stopped connecting to my WiFi. It was only online for about 5 days total.
    - After a couple of additional attempts I gave up.

    Bottom line: WiFi connectivity is key for this product and both units had general connectivity problems in my house where other devices seem not to. Before installing on a heat bump, do some additional research. You might be better off with a non-programmable anyway.

    Does not alway work

    Great idea but....

    Bought the 2nd gen Nest. Returned it because it didn't work with Honeywell air cleaner or humidifier.

    When they upgrade again (3rdgen) hopefully these shortcoming will be corrected.

    Best gadget purchase of 2012

    • Written by from Omaha

    Awesome product. My "do it yourself" skills are limited to changing light bulbs, but even I was able to install this thing on my own in under an hour. Coolest app enabled accessory I've purchased so far. Very easy to use and intuitive. I would definitely recommend it to anyone.

    Great idea but flawed implementation - Heat Pump owners be warned

    • Written by from Beaconsfield

    Great aesthetics and very easy to use both manually and remotely. In fact every part of the system except one delivers on the promises it makes. The problem is that system simply cannot handle a duel stage heating system that uses a Heat Pump as a primary means of heating backup up by an auxiliary system such as a furnace. Despite changing several of the options and pre-sets the fact is your Auxiliary heat will be on far more than ever before costing more not less money to heat your house. The support boards are full of people trying to solve the issue, including re-wiring and fooling the system into thinking it’s in a different part of the country (it sets some conditions depending on where in the country it is and what the weather is like).
    The answer I received from Nest was to disconnect certain wires during certain weather conditions….plain stupid.
    The biggest worry is that to date I can see no recognition from Nest that this is an issue at all. Technology always needs debugging but every day that goes by with this product is going to cost you more and more money in heating bills if you have a Heat pump and auxiliary system….be warned.

    Does not work!

    • Written by from Gloucester

    After purchasing the Nest thermostat at my local Apple store (along with $2,500 worth of computers), I installed the Nest in my vacation condo so I could turn up the heat before arriving after a prolonged absence. Three days after I left, the wifi quit. On returning to my cold condo, I installed a new router. A few days later over the holidays, the Nest wifi controll quit with a "low battery" warning. (The router is not the problem.) With sub-zero temps outside, the Nest defaults to a dumb thermostat...a very expensive dumb thermostat. At -8 degrees F, can it be trusted to keep the pipes from freezing? Bottom line: easy to install, very pretty, doesn't work. (Apple: warn your customers!)

    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)
