    Disaster, waste of money and time with totally useless tech support

    • Written by from Chicago

    We bought one and got it to work to run the heating, but couldnt connect to internet. Then as suggested by Nest, we reset, restarted the device and since then it didnt detect the heating. After wasting 2 hours on the phone with tech support, they couldnt solve the problem. We said FINE, we sent the wiring and the picture to Nest compatibility email to get their advice. After a few days we got an email saying it wouldnt work cause we have high voltage which is absolutely wrong. Not sure how to trust such tech support who cannot even diagnose high voltage from low voltage, let alone to help with the rest. I strongly not recommend this product as it is over priced and not working. it just looks fancy and the idea of how it supposed to work is enticing, the reality is it's not working. period!!!

    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.

    Stopped working in the middle of a cold night!

    • Written by from Pitman

    Suddenly stopped working in the middle of the night! Woke up to a freezing downstairs and no response from the thermostat. Looks like my 7 month old baby will be sleeping in the cold again tonight. Total rip off!

    NEST LEARNING THERMOSTAT DOES NOT WORK!

    • Written by from BABYLON

    I am an architect and we were pretty excited by using this thermostat in several of our projects. One third of them couldn't even connect to the equipment they were suppossed to regulate even though they were compatible as per Nest's list of compatibility. And the other third would work OK for one week and then die.
    We tried working something out with Nest.com directly but they do not have real Customer Service. If you call, they'll have you waiting for one hour and then the call will magically fall and they will never follow up nor answer your emails. DO NOT BUY THIS PRODUCT. IT'S A NICE CONCEPT, BUT IT DOESNT WORK YET!!! SO FRUSTRATED BY THE LACK OF RESPONSE OF THIS COMPANY. NEVER AGAIN!

    Does not work with Carrier

    • Written by from Reston

    I purchased a Nest for my wife for Christmas. Before opening the box, I watched the nest online installation video and went to the nest compatibility website. The website instructed me to take a photo of my existing wiring and send it to nest customer support. I called nest and spoke to a tech after a very short wait. He advised me that my nest "may not be compatible" but had me continue to investigate. After an 18 minute call, he determined that i should go ahead and instal my nest. After installation, my nest said a wire was not installed correctly. I went through troubleshooting and called the support telephone line again. This time they said "because of the proprietary wiring (in the photo i had previously sent) your nest is not compatible." I then went to google and immediately found an article on nest.com that explains Carrier Infinity systems are not compatible. I don't know why the box doesn't say "not compatible with Carrier Infinity Systems" and I don't know why the first phone technician didn't say "not compatible with carrier infinity system."

    Don't buy a Nest Thermostat - Low Battery = no wifi

    • Written by from San Francisco

    The Nest Thermostat simply does not work. I have owned and returned 5 Nest thermostats. They look great until low battery notification appears and then no wifi connection. So really no Nest remote functionality. It may look better but internally it is a poor design and doesn't work. I replaced 2 Nest Thermostats, and in less than a month both had low battery problems. Just to be clear, you can not access or change the battery on the Nest thermostat. I am going to try the Honeywell. Have a good day.

    Was good until version 4.0 software ... now leaves house without heat

    • Written by from Madison

    Loved my Nest thermostats so much I bought 5 more for friends/family. Since the software updated to 4.00 in mid Dec (who releases a major software update during the coldest winter in decades), the Nests have been failing with dead batteries, including those with c-wire connections (full voltage so battery isn't required). Apparently 4.01 isn't helping any and Nest isn't globally releasing it, you have to beg and plead to get it.

    Avoid these until Nest figures out their software issues ... I've taken the Nest Protect alarms off my want-list.

    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.

    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!

    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.

    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.

    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.

    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.

    Fantastic times 3!

    • Written by from CHICAGO

    Have had one installed in our weekend home, and recently installed two more in our primary home. Installation is so intuitive, even I can do it in about 10-15 minutes per. I've always turned off the learning/auto-away functions and use it only to adjust when we'll be away, and to turn back on a few hours before we return. Very elegant app, and great looking with any decor. Love the nests.

    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.

    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.

    NEST ROCKS !!

    • Written by from calgary

    Well if that wasn't the easiest installation I have ever done, even for a woman...lol
    I had it up and running within 20 minutes and it works Excellent so far.
    Every thing is explained to a "T" and pretty much child proof..
    I'm on my way for the first day as to a schedule for my NEST.. will inform you all at a later date.
    VERY HAPPY so far .... I love the fact that you can control your heat from your phone app..
    especially if you have pets! A++

    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!)

    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!
