    Do NOT buy

    • Written by from Calgary

    We have had two Nests for a year in our new home. They worked fine until November when our main floor Nest started reading incorrect temperatures and blowing cold air whenever the incorrect temperature was higher than the set temp. This Nest was replaced by the company. Now in January in often freezing Alberta our upper floor Nest is doing the exact same thing. I called Nest and they are sending a replacement. To my horror, I was shovelling snow outside yesterday when I walked by my two AC units and saw the upstairs unit was actually running. This now made sense why it was freezing in my house. The problem is, we did not have the AC connected to the Nest for winter, I quickly shut the entire thermostat off and the AC was still running!!!!!! How can this be? I know it is a Nest issue as this happened to both my furnaces within a month of each other. All of this happened after the software update in November.

    We will be at the hardware store today buying two Honeywell units. I really wanted this Nest to work as the concept is fantastic and it also looks amazing in my modern home but holy smokes, this is crazy town. Come on Google, you are going to be seeing legal ramifications if you can't get this fixed fast. I will be getting my furnace and AC units checked to see if any damage has ensued.

    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.

    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.

    Over priced and frustrating

    • Written by from TAMPA

    I have had a nest thermostat for over a year. While it was easy to set up initially I feel this thermostat has given me more frustration than convenience. From day one the mechanism has never turned fluidly, seated properly against the base, or clicked properly when pressed but I could overlook all of these issues if it weren't for so many other shortcomings.

    As others have mentioned there is no temperature hold button to override the auto schedule… This is particularly frustrating when you are home on vacation and have to continually readjust the thermostat after the schedule has changed it.

    One of the more shocking design flaws of this thermostat is that the act of touching it alters it's temperature reading. There is a MAJOR design issue where touching the outside ring and turning the selector affects the temperature sensor causing the indicated temperature to increase beyond the actual ambient temperature. FAIL

    Another prevalent issue has been that the thermostat will lose connection (go offline) and be unreachable from a mobile device. This is particularly frustrating when you combine it with the above design flaw of touching the thermostat, LOL.

    In closing, I cannot recommend that anyone purchase this thermostat considering the cost and poor design quality. It simply has too many design issues to be a true competitor in this market.

    Neat when working...until it doesn't - caution!

    • Written by from Bloomington

    1-year after install the Nest failed.

    Came home on a freezing day to the Air Conditioner being told to run by the thermostat. The Nest could not shut the unit down - on/off = no change - had to turn off the circuit breaker. Their technical support confirmed the base plate had failed and they sent out a new one. The new base plate fixed the issue. Research shows I'm not the only one with this issue.

    This kind of failure can damage property since I live in a state with climate extremes. It's not worth the risk and I'll be getting rid of it.

    The NEST Thermostat and NEST Protect.... the truth.



    I have owned both of these item since they came on the market. I thought they would be good to have to protect our home and allow us to communicate with the items and control our home while away. After owning both of these for some time now this is our experience.



    Our home:

    We live in rural Ontario. We have an all electric home with 200 Amp service and a 15KV generator to supply power when the power goes out. Our ISP provided a Siemens Modem and behind it we have an Apple Extreme 801g/n router to provide wifi. We now also have a UPS to handle the wifi until the generator starts during a power failure. Even in a power failure our ISP provides Internet access.





    The NEST Thermostat:

    It was easy to install and worked right out of the box. It is easy to use in person and controls our electric heating just fine. It was only after a power failure we began to see the issues. The NEST does not like to reconnect to our wifi after a power failure. I have always had to wait until I return home, walk to The NEST and select “wifi” and press it. Then it connects. The NEST is only 3 meters from our wifi router and signal strength is reported to be “excellent” at 86% when tested. So signal is not the issue. To get around this I’ve installed a UPS so the wifi never drops. This has solved this issue it would appear at the moment. No battery issues so far. Other issues: It has no idea where we live. I had to trick it during setup as our location is not available. Occasionally it complains about setup issues that when checked don't exist. On occasion it will not light up when approached even though this feature is turned on. I have to poke it to get it to light up. All else appears OK. Do I trust it for an extended vacation in the winter: NOT ON YOUR LIFE.



    The NEST Protect:

    We purchased 2 of these when they hit the market. Installation was easy and they both worked out of the box. The issues with both of these units are the never-ending stream of false alarms, always when we are away. We rush home to find NOTHING.!! Even while writing this our bedroom NEST Protect went off telling us about smoke in the bedroom that isn't there. We’ve received Emails telling us our bedroom is full of smoke. When we arrive home our cat is sleeping on the bed so we can safely assume the alarm in the house did nothing. We’ve had alarms of power outage when there was none. We’ve had alarms of fire when there was none. THEY ARE A PAIN.



    The NEST Support:

    In a word: it’s non-existent. When you refer to the web site there is a “Contact Us” area but it only takes you to another page which lists HELP and The Community. In other words “You bought it and you’re stuck with it and we don’t want to talk to you to help you with your problems”. If you do leave comments in The Community someone will answer but it’s days later.



    I would in no way recommend either of these products to anyone but I did buy them and yes I’m stuck with them. I may end up dumping them on eBay and going back to Honeywell products that actually do work.

    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.

    Don't buy!

    • Written by from Toronto

    I owned it for a year and a half without issues. After automatic update on the thermostat, battery gets drained which results in your hvac shutting down. In Canada, it's not a good thing when you have kids and outside temperature is -20 Celsius...
    I contacted Nest who could not troubleshoot and solve the problem . They sent replacement unit for free but had same battery issue. There was no work done on furnace or change on internet router, problem was clearly with the product software update. Save your money and buy product that does not look as nice but WORKS, AND IT IS NOT THE NEST.

    Unstable

    • Written by from Uxbridge

    I normally don't write reviews but this product is so unstable it desires one. After owning my device now for over a year, I can tell you that my device is rarely online, Nest customer support is not helpful and my hydro/heating bills have actually increased from using this product.

    You have been warned

    • Written by from Newton

    Went through multiple emails making sure NEST was compatible with my heating system. Had the NEST professionally installed. On the 2nd day it just started blowing cold air. It is 40 degrees outside now and 42 degrees inside and I have to have the old system installed back on. Horrible gimmicky gadget here.

    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.

    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.

    Worst Thermostat EVER!

    • Written by from BUFFALO

    I can't even begin to say how upset I am to have to title the Nest Learning Thermostat as "The Worst Thermostat EVER." For the "cool" factor and appearance it was in "A" in my book. I installed it in November 2014 and it worked like a charm... for 4 weeks. The we came home to a house that was 80+ degrees in winter (in Buffalo no less) and found "the base unit was malfunctioning" preventing the nest from shutting off. The "overnight" Fed-Ex replacement arrived in 2 days which meant I had to manually turn on and off the furnace from the circuit breaker. The new nest worked great... for 3 weeks before it did the same thing. Another call to nest with their crazy long wait customer service stated this was a known issue and another unit would be sent... "overnight." Four (4) days later FedEx showed with my third unit in the same number of months and it worked again...well. Yesterday, after only 2 1/2 weeks from install, the Nest again malfunctioned and my phone call to their customer support agent and "senior" agent finally concluded my energy effecient Heil forced air gas furnace was "incompatable" to the nest. What?!?!? I have finally had it and went straight to Home Depot and purchased a Honeywell "Smart Thermostat as a replacement. My last honeywell thermostat lasted over 20 years and I'm just hopeful this one will last longer then the Nest's.

    So...divert your eyes from the aestetic appeal of the Nest Thermostat and purchase another brand. Maybe in the future the Nest will be viable, but until that day you owe it to your home to find another thermostat.

    WENT DOWN HILL FAST!! DONT BUY!!!

    • Written by from Covington

    Have had the Nest 2nd Gen since the release date and WAS absolutely amazing. App worked great never and problems. Unit was easy to hook up and is great. Heat is set to 70 the heat will kick on at 69 and shut off when it hits 71, so it's not constantly turning on. You can fine tune the temp to around quarter/ halfs without it saying 70.5 or 70.25. It was great!!!! Amazing!! Best thermostate ever!!!
    THEN I DONT KNOW WHAT HAPPEND, TERMASTATE APP WORKED ONLY A QUARTER OF THE TIME. EITHER WOULD SAY OFFLINE OR YOU WOULD CHANGE THE TEMP, CLOSE THE APP THINKING YOU CHANGED IT AND IT DOESNT CHANGE IT. EXTREMLY FUSTRATING BECAUSE I USE THIS DURING WINTER TIME TO FINE TUNE TEMP UPSTAIRS SO MY TODDLERS DONT OVER HEAT OR FREEZE WHILE IAM UPSAIRS AND I DONT NOITICE IT DIDNT CHANGE UNTILL MY BABY MONITOR ALARM GOES OFF BECAUSE ITS TOO HOT AND I HAVE TO RUSH DOWNSTAIRS TURN IT OFF (HAVE TO TURN THE NEST DAIL AND IT CLICKS BUT DOES NOT REACT UNTILL 10 SEC OF TURNING THE DAIL) THEN GO AND OPEN THERE DOORS TO LET OUT HOT AIR. ALSO UNIT SHOULD TURN ON AND DOES NOT AND I TURN THE DAIL TO GET IT TO SHOW TEMP AND TURN ON AND CLICKS BUT DOES NOT REACT UNTILL 10 SEC LATER AND IT JUMPS 10-20 DEG TO THE SET TEMP. ITS LIKE ITS ON SLEEP MODE OR ITS ALWAYS DOWMLOADING OR UPLOADING AND TURNING THE NEST OFF UNTILL YOU FORCE IT TO TURN ON.
    1 YEAR AGO I WOULD HAVE TOLD YOU BEST TERM EVER AND HAVE TOLD FRIENDS THAT ASKED, NOW I WOULD SAY ONE OF THE WORST TERM EVER. SEEMS LIKE AFTER GOOGLE BOUGHT NEST ITS WENT DOWN HILL FAST. IAM REPLACING MINE SOON AND WILL NEVER GO BACK TO NEST, TOO BAD TOO. WAS GOING TO GET A HAND FULLY OF NEST PROTECTS AND AN UPSTAIRS TERM AND DROP CAMS. NO WAY I WOULD EVEN CONSIDER IT, EVEN IF IT WAS ALL FREE!! I AM NOT EVEN GOING TO SELL MY NEST, I COULDNT DO THAT TO ANYONE. IAM GOING TO TAKE A SLEDGE HAMMER TO IT.
    BY THE WAY HAVE LEFT REVIEWS AND ASKED TO BE CONTACT ABOUT THIS MANY TIMES AND STILL NO CONTACTS OR FIXES. AS I SEE BY OTHER REVIEWS ITS NOT JUST A ISOLATED THING.

    Very Dissapointed

    • Written by from East Falmouth

    The Nest is a real disappointment to us. It simply tries to be too smart and generally gets everything wrong. The advanced functions like "scheduling" and "away from home" never get it right and it is essentially impossible to just set a temperature have the Nest leave it alone. This company obviously has too many computer programmers and not enough human beings. It certainly does not deserve customers. Awful product.

    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!!!
