    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.

    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.

    NEST is still a baby

    • Written by from San Francisco

    It's hard I know, but control that excitement and don't buy nest yet. I wanted to love it, and still do want to. However after purchasing and having loads of independent problems, I see a LOT of dissatisfied customers with similar issues and worse. What's more, is their support team is always overloaded, and the replies on Nest.com are totally canned responses. Hold off until there's more competition!

    AMAZING PRODUCT THAT HAS GONE DOWNHILL IN 7 MONTHS

    • Written by from SODDY DAISY

    I have been a NEST devotee for 3 yrs. We have 2 installed and they worked with amazing performance until about 7 months ago when software upgrades began. Now the app shows OFFLINE randomly, the thermostat is connected through my Airport (all my WIFI stuff is Apple and nearly new) so I have no remote control. Then I have to touch the dial to get it to connect thru the app. What are they thinking?? NEST support has become a little more responsive in the last month, but even after warranty replacements, the two new units act the same. APPLE--you need to pull this product from your stores until NEST PROVES they have fixed these issues. There are HUNDREDS of threads on the NEST community forum, on these reviews, and on public blogs about this horrendous issue. There is no recourse here but to strangle their business. These problems will occur to every one who buys these, it is just a matter of time. Please pull this product until they get this fixed!

    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.

    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.

    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.

    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.

    Don't bother with this product

    • Written by from Dallas

    The good things - nice design, looks cool, easy to use, common sense user interface.

    Now for the bad things. It does not work! Nest has replaced my thermostat one time. The issues are with its ability to be a smart thermostat. It is not. The away function does not work. While Nest will tell you the software only kicks in during the daytime hours, it decides if you are away at all hours of the day or night. For example, at 6PM, it decides that I am away even though it turned on when I came home. It will also go into away mode every hour or so during the evening. So, if you change the temp at 8PM, by 8:30 it will reset to the temp for away mode. And, every morning when you wake it is in away mode.

    To solve that, I decided to use the "schedule" mode. That does not work either. If you only set a single temp and never touch it again, it works fine. If, however, you ever push the temp up or down slightly, it remembers that and constantly resets itself to the new temp. I can't recall the number of times it resets to 65 in the AM, or resets at other times on its own. It takes several times of over riding the temp to get it to reschedule the right temp.

    Quite simply, this smart thermostat is stupid. I would avoid all their products. While the shifting temp is an inconvenience, I would not trust their smoke or CO detectors.

    DON'T BOTHER WITH NEST

    • Written by from East Greenwich

    The Nest thermostat looks sleek. Unfortunately it doesn't do what it should. After about 8 calls to Nest (always very pleasant advisers), my thermostat still goes "Offline" without explanation. This means that I cannot control the temperature remotely, which is the whole point of the thing. Save your money and by a much cheaper one at Home Depot.

    Awful for Vacation Home

    • Written by from Philadelphia

    Though this thermostat is very cool looking, and the learning feature interesting, it lacks two basic feature that make it terrible for a vacation home.
    First, it does not have a low temperature alert that emails you when the temperature drops below a certain level. This would give you a chance to try to get ahead of freezing pipes.
    Second there is no temperature hold feature. Sometimes I want to just set a temperature and leave it there... The most basic of functions.
    People have been complaining about these issues for the past couple of years on the Nest boards and the complaints are falling on deaf ears.
    Going to try to sell my 2 nests and get Honeywells.

    Nest is UNRELIABLE

    • Written by from Hauppauge

    STAY AWAY from this product if you intend to use in a weekend house, or any home that isn't occupied everyday. IT is unreliable. The battery keeps going dead. The patches they've sent to fix are worthless. do NOT buy this product. It is TOO unreliable.

    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.

    Nest, Not what us used to be...

    • Written by from Oakdale

    I purchased my Nest 1st generation 5 years ago, and it 'was' a phenomenal piece of equipment. It managed my heat pump, heating and cooling requirements better than my old mercury driven thermostat... The Nest DID save me money on my electric bill. However, Nest must have recently had an update to their device which I'm finding 'I cannot manage my FAN air function.' During the daylight hours when my system is demanding AC, Nest operates as it should by providing AC. In the evenings when it's too cool for AC and still too warm for HEAT, my FAN does not turn off... It constantly runs even after I manually command Nest to 'OFF.' I find I need to manually turn the AC, HEAT PUMP unit to OFF to force the fan yo stop operating. Hence, I'm no longer saving money on electric/heating bill. Note: For some strange reason, this issue is only a problem during the evening hours. I'm considering removing my Nest and replacing it with one b their competitors.

    AVOID NEST; Coolest look; Inferior functionality

    • Written by from Beverly Hills

    This is a very cool looking, poorly designed thermostat.

    If you are looking for a thermo that is easy to use this is NOT it.

    1. There is no on-off switch; that's basic. I want to turn the effing system off. There is no simple, obvious way to do that. I want to turn the effing fan off. There is no simple, obvious way to do that.
    2. No tech support, except FAQs and the "community." Clearly cheap for apple. Clearly inadequate for a consumer.
    3. Navigating the system is cumbersome, limited, sequential screens.

    Do yourself a favor: Get a Honeywell or some other brand that does not look so cool but that has a good display and can be easily used.

    Great product, but don't upgrade yet, especially if you live in the South

    • Written by from SLIDELL

    Have had my nest almost a year. Installed it the end of last summer. Love all its features except 2:

    The first is the way it plugs into the wall. It is very easy for family members to knock it off the wall while trying to set it. It is better set from your iPhone. This would not be an issue if people were not playing with it so much do to the main issue in the next paragraph.


    The main issue with the Nest is the lack of ability to control humidity settings. My old thermostat allowed this. I have discovered that living in the South, this is a very important feature for comfort.

    When the nest turns on to cool the house, the humid cold air is annoyingly uncomfortable. Turning up the ambient room temperature to correct this results in a room that feels to warm after the AC stops blowing. So either you feel a little too cool when the AC is blowing, or a little too warm when it's not. This is not extreme, but just enough to be annoying if you spend time in your house. I don't notice it when I return form work and go to bed, but I do notice it on weekends and days off when I spend time in the house this summer.

    I am well past the learning curve for a new device, and have not solved this, but I do see where the Nest measures the humidity. So it should be possible for the company to allow us to control it.

    Since a basic wired thermostat has a humidity control feature, I am surprised that Nest does not. If I was not so lazy, I would re install my old thermostat. If Nest solves this problem, I will upgrade.

    Not worth the money

    • Written by from Sandy Springs

    First - Nest lacks the most basic of thermostat functions: Hold Temp. Enthusiasts will tell you the Nest features eliminate the need for it, but Friday was a holiday and there was no way to tell the thing not to run the usual weekday program.

    Second - Auto Schedule makes random unexpected changes. The ability to confirm those changes would be great. My thermostat decided that I didn't want the temp to drop to 70 degrees at 10 PM anymore and cleared that part of the program even though if I made that adjustment, I only did it once. So Auto Schedule is off.

    Third - Auto Away overrides the schedule. So rather than having a comfortable temp in the house when I get home from work, like the program is set for, the thermostat goes to Away when I am at work and I have to interact with it to get it to run the program. What is the point of a schedule if the thermostat doesn't follow it? So Auto Away is off.

    The novelty features of Nest don't really work. I'm pretty sure that the thermostat is not smarter than I am, but it thinks it is and does things it thinks I want. I shouldn't have to interact with my thermostat regularly to get it to do what I want it to, but that is what the Nest requires.

    There are less expensive wifi connected thermostats that do what the Nest does. They don't have the fancy metal ring around them, but that is about all you are getting for the extra money. I wouldn't buy another one.
