    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.

    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.

    breaks easily

    • Written by from miami

    bought the nest at Christmas in three months it broke

    the technician nest recommended me to use in my area told me he's seen a lot of them break

    do not buy this product
    wish apple did not carry it because I thought apple would have not carried it if it was not reliable
    now I have my old thermostat and everything works well now

    try Honeywell

    if anyone from nest reads this build a more reliable product before releasing

    Give it a try, so long as you can return it.

    • Written by from West Hollywood

    I read a bunch of reviews online here and other websites. People love it or hate it. Mostly because it works for some and not for others. I bought Nest a couple of days ago. The batteries continually die, causing the Nest to shut down and resulting in me having no control over my AC or heat. So for me, it didn't work. When it's on, it looks great. The concept is fantastic and I have friends who have Nest and they have been problem free, which is why I decided to give it a shot.

    It seems the best option is to buy it from Apple or from somewhere you can return it, should it not work for you. Also, only if you can install it yourself. It took me about 20 minutes. So when it didn't work, I spent another 20 minutes disconnecting it. All I lost was the time for the install and removal and two trips to the Apple Store.


    My Nest is completely compatible with my system and when it was on and had power it controlled AC and heat just fine. I do have an RC wire, which is supposed to provide power, but that must not be the case, hence the frequent shutdowns for loss of power.

    I hope this helps clear up the confusion for some people on why there are 5 star reviews and 1 star reviews for the same product.

    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!!!

    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.

    I really wanted to love it

    • Written by from Chesapeake

    I wanted to love it but I love being comfortable in my home more. I purchased 2 second gen Nests for my home and immediately I noticed that the batteries drained, they lost wifi, and then shut down. Several times I came home to a freezing home and had to light the fireplace while I manually charged the Nest with the mini USB. No help from Nest support and finally I had to replace them with the old simple programmable thermostats ($19.99 at Home Depot) - problem solved! Waste of $500.

    Reading the forums and comments lets me know I'm not alone.

    Check the type of system you have before buying

    • Written by from Toronto

    I am the owner of a 1st generation Nest Thermostat. It worked amazing with my old single stage mid-efficiency furnace. The furnace quit last week and I replaced my furnace with a 95 percent high-efficiency furnace with a dual staged fan. Nest thermostats (1st & 2nd generation are not compatible with furnaces with multiple stage fans - as per Nest Technical Support. I had to revert to using my old programmable thermostat and I am now the owner of a $250 hockey puck.

    Has Potential. Needs A lot of Work

    • Written by from Baton Rouge

    I did my research and decided I would try the Nest. I previously used an Ecobee in my last home and loved it, the idea of the Nest using software and algorithms to "Learn" and automatically set to away to save energy seemed amazing. I do not however have a set schedule and after 2 months it is still in learning mode. My girlfriend and I both have the Nest apps on our iPhone, Perhaps if it were to use location to know when we left the house, and when we are going to return... it could help but to my knowledge does not. There have been times when I am in another room and it sets to "auto away" increasing the temperature and making it very uncomfortable. Other times in the middle of the night I will wake up sweating, realizing the Nest decided to raise the temperature 5+ degrees. Aside from that... installation was extremely easy, it looks very nice on my wall, and needs a lot of work from the Nest team.

    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!

    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."

    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)

    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).

    Nest not as advertised

    • Written by from Salisbury Mills

    Not satisfied with operation after 2 calls to Nest support. 2 issues:
    1-if not at home thermostat does go to auto away but it also automatically turns itself on and heats to set temperature even when not at home. It is supposed to stay at auto away until it senses someone arrives home.
    2- when at home if set temp is turned down manually it automatically goes back up to set temperature....wasting energy.
    I am sorry that I spent $500 on two thermostats that I find have never operated as advertised.
    I would not recommend this product to anyone.

    good looking terrible product, made electric bill double~

    • Written by from louisville

    I have tried and tried to get this great looking thing to work, but alas we are putting the old thermostat back on. Frustration, every month with our heating bill out of control, and never able to really regulate the temperature in the house to a comfortable temp. Either freezing or burning up. Randomly turns off after it's turned on for 30 seconds and then comes back on for 5 and then turns off again! Don't waste your hard earned money because it looks so cool! Looks are deceiving.

    Heat bill doubled

    • Written by from Charleston

    Swapped an old digital basic thermo for the Nest in Dec of 13. The aesthetic quality of the Nest had me hooked. I had a professional come by afterwards to check it out because the house was taking forever to heat. He said it was installed properly, just a Nest trait. It kicks on the first stage of heat and runs as much as it can with out utilizing the 2nd stage which really heats the house up quickly. My 1st stage of heat was running constantly. Well, it's been 3 months and average temps were with in a degree of the same time last year and my electric bills have doubled each month compared to last year.
    I requested support from Nest 2 months ago and have received no replies. My Nest is going back for an exchange to something more affordable that works.
