    Outstanding product, great practical use of today's technology.

    • Written by from overland park

    Great product. Easy DIY installation and set up. Helps save energy automatically by adjusting temp settings to your impute, either manually or automatically when you are home. It learns your comfortable/preferred temp settings rather than having to program it.
    And you can completely control it (temp settings, heat or cool on and off, etc) from your iPhone or iPad.

    Although not cheap, I bought 2 first generation units for our new house (one for up stairs, one for down stairs) and have been very impressed with easy of operation. I sit in bed at night and adjust either thermostat using my iPhone or iPad (or sit in a hotel room miles away) and see the outside temp and adjust the thermostat if it has not already learned my preferences.

    Amazing

    • Written by from Laurel

    This product is truly amazing. I had a little trouble getting it to work with my system but the nest help center walked me through it on the phone. I would recommend it to everyone.

    Really great, easy to install

    • Written by from HASTINGS

    This product was simple to install. I am by no means a home improvement do it yourself type. I've never even thought of taking apart my thermostat before. However, this was very easy to install and has been a joy to use. i'm very impressed and happy with this product.

    One of the few products I've ever bought that exceeds the hype.

    • Written by from LOS ANGELES

    1. Absolutely love the smart software - I've been using for about 5 months and the bills are about 15% lower than last year. The nest should pay for itself in savings before 2 years.

    2. Love being able to control from my phone. I recently forgot to turn off the heat when I left town. And when I smugly went to the app to do it, it had already gone to auto-away when it stopped detecting me in the house.

    3. Design. I get curious and positive comments about it from just about every visitor.

    I feel like an iPhone got my old thermostat drunk, took advantage, and 9 months later the Nest was born. Great product, giving as gifts to folks and brother this holiday.

    Nest 1st generation

    • Written by from TROY

    I've had my Nest thermostat since December 2011, and have been very pleased with the results. Also, glad to see that even though new version came out - I still get same software updates and functionality. 2 neighbors have since bought one also.

    It's a Struggle!

    • Written by from Lawrence

    Be warned, if you don't work a 9-5 job, with a set schedule and regimented weekends you will CONSTANTLY BE FIGHTING with nest to keep your house comfortable.

    Nest is constantly changing your schedule to adapt to how you've set it i the past. An extra day off in the middle of the week (like a sick day) and you'll find yourself shouting at the wall every 20 minutes because nest keeps raising the temp back up to 78! The worst thing about this $250 thermostat is that it lacks the basic function of a 'hold' feature.

    Of course you can turn the learning part off but it is not easy to do this and once you do, well, you realize you've paid 6 times more for a thermostat because it has a feature that you've had to disable.

    We've woken up sweating in the middle of the night and found that Nest had decided to turn itself up 5 degrees.

    On the plus side it looks cool and was easy to install.

    On the downside in practice it is annoying and lacks features like a hold button that is essential for anyone who's schedule is not EXACTLY the same every day.

    It Just Works & Saves

    • Written by from York

    Have three 1st gen units since last December and they just work together. They may cost a bit more but here in PA I saved over $300 just this summer on our cooling costs and came out of last winter with a credit to our nat gas heating cost. The Airwave feature alone makes you wonder what took so long for this feature to come out of the industry. One nice thing is that these units get a software update once released automatically. I feature I wish it had was the ability to just turn on the fan without turning on heating or cooling.

    Like others stated pretty straight forward to install just make sure your system is compatible. The app makes it easy to control while away. In the past while on summer vacation I had someone come in and turn the AC so the house would be cool once back but this year I was able to take it down from 80 degrees in steps rather then all at once.

    Fabulous

    • Written by from Pleasanton

    We LOVE the nest - I installed it myself, processed 2 updates and I couldn't be happier. We put our nest in the home we purchased to retire to. We aren't spending enough time there yet BUT with our Nest we can set to warm or cool for when we arrive. It "learned" our habits and has already paid us back the investment.
    I did have to contact customer service when I was installing and they were GREAT - helped me out and made sure it was running perfectly.
    So, what are you waiting for? You will be wondering why you hesitated. DO IT !
    ( I don't know any employees at Nest but I'd LOVE to work for them that's how much I love this product!)

    Issues with backplates can show up any time

    • Written by from Chagrin Falls

    I purchased my second generation Nest in November 2012. I enjoyed 10 months of efficient use and loved the product, until one night in August while running in cooling mode, it started making a simultaneous call for heat and caused my HVAC system to go completely haywire. Emergency HVAC calls and $700 later it was determined it was determined the Nest had gone bad. At that point Nest didn't tell me about the significant number of issues with backplates that had been cropping up -- I got a replacement that also failed. This time it started running my air conditioning in heating mode when it was 30 degrees out. My third backplate also went bad. The problem seems to stem from Nest's use of FETs which makes it highly intolerant of normal voltage swings found in HVAC units. The nightmare of trying to get Nest to refund my purchase for this sudden incompatibility has been painful -- more than 4 hours of waiting with tech support. The Nest is a great idea, but the company is showing real issues with product quality, reliability and support that needs to be addressed.

    Stopped working

    • Written by from ABINGTON

    I bought the Nest about 6 months ago and had it professionally installed along with a brand new HVAC system. It worked fine until about a week ago went it got cold outside. The Nest had both the heat and the AC running at the same time. I had to go out and pull the breaker to the AC unit. I had the HVAC company come out today and take a look at it. The confirmed that the nest was sending the signal to the AC unit to turn on. They could not do anything about besides leave the breaker pulled. The other option is to remove the nest and replace with another controller (not a nest). I will now try calling Nest to see what they will do. I am clearly experiencing what is happening to a lot of people. Will be interesting to see how Nest handles it. Makes me mad because I really like the way the nest looked and functioned but clearly this is a huge problem that will most likely have me throwing the nest in the trash.

    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.

    Wow! Smart product. Great start.

    • Written by from Liberty Township

    Nest is a GREAT start! Here's how it could be even better.

    Missing features:
    -Outside temp displayed on screen.
    -Forecast (hourly and or weekly) displayed on screen.
    -Integrated usage of hourly temp web predictions to anticipate whether or not it needs to heat or cool or if it can just wait for the home temperature to adjust naturally. Why do I want my thermostat to cool my house 1 hour before the temp is predicted to drop? Nest has access to this data via WiFi.
    -Phone app GPS to learn when I'm away and when I'm headed home.
    -Developer app support (3rd party app development). I don't need to play Angry Birds on my thermostat but I would like to learn what a community of developers would dream up. I'd buy a cool app or two.
    -Centralized NEST hosted forum for feature suggestions and bug troubleshooting.
    -Monthly usage summary that suggests slight reprogramming changes that could maximize efficiency and instant implementation if user confirms.

    Horrible time with Nest...

    • Written by from highland beach

    I picked up two Nest thermostats last week. One is working fine, the other not so much. My AC units in the home are all the same. I sent in pictures of my thermostat was told I was good to go, etc...

    At this point I have returned 4 units... I was told each time my terminal (the thing the wires plug into that mounts to the wall) had a bad "G" connection N26 error and to return it for a replacement. I was finally told that small voltage spikes can kill the base unit/terminal and cause it to need replacing, a common issue?? Seems odd that a $20 20 year old thermostat can take it but the $250 Nest can't?

    I then was told my system is incompatible?? But its working fine on the other one with the same AC model unit... Makes no sense.

    I then call in my AC guy and spend $200+ on some troubleshooting to be told the same thing about bad base unit/terminal / voltage spikes replaced the base again 4th time and it worked for about 8 hours. I wake up at 3am hot the fan is not running ac is frozen... Check the wiring under equipment on the nest and guess what!? "G" connection N26 error like every-other time. No solution given when I called this morning.

    I then called concerned about my working unit, will it go down so easily with a small spike?

    I was given no solution and told to return all of the units if I was really concerned... FAIL. I will not be recommending the Nest thermostat to anyone regardless of their experience with technology or AC units.

    Love/Hate

    • Written by from Levittown

    I loved the idea of this thermostat so much, I bought two. The first hurdle was installation. I chose a professional installation through Nest, but after 3 failed attempts to schedule "local" installers on their list. I gave up. It seems that the contracted installers have a certain mileage limit they commit to as Nest Certified Installers, but won't actually travel more than 20 miles or cross State lines to do a job. At least that's the way it is where I live. Nest would schedule and the contractor would call me directly and tell me they couldn't do the job and I should call Nest to find another installer.

    So, I lost two days of work dealing with that hot mess. Nest was kind enough to refund the install fee and my local Heating guy took the amount I was quoted by Nest. So, it was a Win/Win except for having to burn two days of vacation. The install was a breeze for the Heating Company tech. He had one in his home and one in his vacation home. He had nothing but good things to say.

    The last six weeks have been great. I've been watching energy savings rack up on the iOS App by setting my heat to a 50 dgree low while away 5 days per week. In fact a friend just asked me today how I liked the T-stat. I raved about it and he plans to buy one tomorrow. Then I got home.

    The entire upstairs was cold, it's 18 degrees outside and snowing on a Friday night. My upstairs Nest was showing an error E30. One of the wires was not giving power. If there is one thing I have learned in my 40+ years, it's that the wire itself is hardly ever the problem. The problem is usually at the origin or the termination point. So, I fired up tech support on the Nest site, got a case number and called the tech support line. Two hours later, many wire swaps, power cycles, trips to the fuse box and transfers of support personell. I was left with a choice between shorting the wires so that my Oil Burner runs continuosly costing ooodles of cash or sleeping on the couch and hoping the upstairs pipes don't freeze. The Nest tech thinks it's the Tstat base. It's Friday, my new Nest arrives on Tuesday. Really? This product may not be ready for prime time.

    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.

    Update killed thermostat.

    • Written by from Woburn

    Newest update causes the battery to run down and shut down. In the cold north east no thermostat is a big concern, but not to Nest. With no battery you can not even manually turn on your heat!!!! Frozen pipes while you are on vaca? Elderly in the house? They claim to have a fix but upon calling they admitted they can't even roll back to a working version.

    Do not buy a Nest

    • Written by from Mississauga

    The Nest is not reliable. We installed ours 2 wks ago and it does not work - we are presently freezing in our home. Yesterday, we came home from work as usual and it was mysteriously in "away" mode. Today, we came home and it had the air conditioner and furnace running at same time. The house was freezing. We turned off the air conditioner at the electrical panel - we tried to do it at the Nest but it did not work, so the only option was to flip the breaker. We then put a thermometer beside the Nest and saw that it reads 8 degrees less than is displayed on the Nest, meaning that the Nest does not properly measure the ambient temp. We went to their website for troubleshooting - it is a useless piece of fluff. We called their 1-800 # and did not get service after almost an hour on hold. So, here we sit, freezing and disappointed, in our house in November! We will return to Honeywell asap. Do not get a Nest!

    FAIL

    • Written by from Oakville

    Don't be fooled by the shiny, sleek look. This this is an epic fail that can cost you hundreds of thousands of dollars if you live in a cold climate. This is an expensive consumer electronic device and NOT an HVAC device. The customer support is non existent apple-like "geniuses" who are totally untrained for the problems this thing generates
    I had constant stop WiFi connectivity issues and several losses of power to the furnace and AC and low battery warnings.
    I lost count of how many times I came home to a boiling or freezing house
    One day, It failed on a nasty cold snap and my water pipes froze, my basement flooded with cold frozen water and destroyed my finished basement and everything in it.
    The HVAC guy said it was the nest. He refuses to sell them because of the constant problems that can easily become catastrophic.
    Don't be an idiot like me. READ THE REVIEWS and stay away!!

    Buy a cheap honeywell or something that is designed as a real thermostat. The aren't shiny, but they work. This POS does NOT!

    C wire needed but then all is good

    • Written by from Glenwood

    Good - easy to use free app, sleek, simple, great phone help

    Bad - needed C wire, suggested Pro install would bump cost into other more robust system price range such as Honeywell

    I was lucky I had an unused wire in the wall and was able to run 24v from my plenum heater panal. Happy now, but almost did not work. Talked with a local installer who said he always ran C wires to the unit.

    Easy to Install! Save a lot of Money...

    • Written by from Washington

    My old neighbors had the first generation NEST and they swore by it. They told me that in a couple of months (3 in total) they had already saved as much money as the NEST had cost them. I was a little suspicious of the hype behind it all, but after the second generation NEST came out, I finally gave in and bought it.
    It took a little more than 30 minutes to install and just watching the video that NEST has on the website is enough for you to do it.
    After a week, it learns your pattern and makes one initial one for you to save money, but it never really stops to learn. Its AWAY mode is brilliant and having access to it on your iPhone or computer is priceless... I would highly recommend it to anyone...
