    Simply amazingly... simple!

    • Written by from Rockport

    What's so incredible about the Nest is that it's so easy to install and use. Like first learning to use an Apple product, everything works so smoothly that you feel that you're missing something. At the same time, you wonder why all the other thermostat companies (Honeywell, Johnson, GE, etc etc) have never been able to even come close to this level of efficiency and performance. After the Nest thermostats will never be the same.

    Anyway, I never thought that controlling a furnace could be so fun. With your Nest account and an iPhone app you can control your home climate from anywhere.

    Not so smart afterall

    • Written by from Athy

    Will keep this short -

    Despite having two units replaced and testing with 8 (yes 8) routers these thermostats hate to stay online. They constantly loose their connection to WiFi and cannot be controlled remotely.

    NEST support state that its a known issue etc etc but no fix.

    Advise. Dont buy

    Great Product. But Let's Get Practical

    • Written by from Pasadena

    I purchased my Nest a week ago. So far it is running as advertised. No issues. I won't talk here about long-term reliability, because I've only had it a week. I would, however, like to add some perspective on installation - in particular, installation time.

    I've read a number of reviews that say you can install the Nest in 15 minutes or so. Be careful about such rosy estimates. First, you have to open the box, get familiar with the contents, and read the instructions. That takes several minutes alone. Once you do that, you have to get to your heating/AC unit and find a way to turn it off. Not all units have a simple "off" switch-mine certainly didn't. So you will either have to find the circuit breaker for your heating unit or the power cord. Depending on where your unit is located, this can take a few minutes. Then I had to disconnect the old thermostat, identify the wires, and use the compatibility check on Nest's web site to confirm the Nest would work for me. Again, several minutes. Then I had to attach the Nest to the wall. As you might guess, the holes for the Nest screws did not match with the holes for the old thermostat, so I had to drill new holes for the Nest screws. Finally got the holes drilled, attached the Nest to the wall, connected the wires, plugged heating/AC unit back in, and, voila! Success! But the entire process took well over an hour - not including the wireless setup and software download. This isn't Nest's fault - it simply reflects the reality of safely installing a sophisticated piece of equipment.

    Again, the unit is working fine, which is why I am giving it 5 stars. But don't rush into this installation thinking it will be a 10-15 minute job. If you do, you will become impatient, make mistakes, and find yourself unfairly hating a very good product.

    Great Design, horrible product with major issues

    • Written by from Riverside

    The Nest has the beauty of Apple design but poor quality product

    The product installs easily and support is good

    After running fine for a couple months I came home to both my furnace and air conditioner running at the same time. This was for three days and house was 90 degrees. The energy costs alone are greater than any potential savings. The danger factor alone for this known problem is high and I can't believe they don't recall the product.

    I received no alerts or anything on the iphone app. It only pretends to be intelligent for minor features. It is has little intelligence for reliably heating and cooling your house which is the main job.

    I went back to a $25 Honeywell thermostat from Home Depot and everything is fine. Nest will replace unit but how could you trust the device.

    Immediate money saving product

    • Written by from Tinley Park

    As soon as we installed this product in our home, we saw our bill start to drop. It is very easy to configure and schedule and it also learns on its own so if you forget to tell it that you are away at work, it will set itself to away for you.

    Makes saving energy more interesting and fun.

    • Written by from Thunder Bay

    I replaced my old programmable with the Nest after reading a great deal of positive reviews. They were right, it's just fantastic. I believe it is saving energy. The temperature feels more constant and more comfortable overall. It leaves little to be desired, except a few things. For one, the app that controls it should provide more information and graphs on the main screen. It was easy to program. I would recommend to anyone that can afford one. It is said they pay for themselves in less than two years. Time will tell.

    Great piece of gear.

    • Written by from Novato

    The Nest was my Christmas gift. It would have been easy to install if I wanted to leave it behind a door, but its too good looking to keep it hidden. The Nest work great, easy to adjust and program, and looks great. I really like that I can control the Nest remotely.

    I purchased the nest a few months ago and let me tell you that it is the best! In the first week of using nest, it learned my heating/cooling habits and I haven't touched my nest since then. It is really handy when you have to go to work and it will go into "Auto Away". It saves a lot of energy that would've been wasted. Good job nest!

    Avoid At All Costs!

    • Written by from LEAWOOD

    I am constantly having thermostat going offline with my 2 Nests. It didn't start until the last software update. Been using the same Airport Extreme both before and after the SW update. Nest is taking way too long to get this fixed. This makes the iPhone app useless since it can't talk to the Nest. Also, no HomeKit or Geofencing support. Once a great product now marginalized. I wish Apple would have bought Nest instead.

    Always going OFFLINE

    • Written by from HOLLAND

    I would rate this stat a 4 star if it was not going OFFLINE all the time.

    I have 8 of the Nest thermostats. They worked fine for the 1st year and a half. Then after a firmware update to 4.3.3 , sometime in November 2014, they all went intermittently OFFLINE. Typically not all at the same time. I've had as many as 6 at the same time being this way. I got with support, which took a while to get to an engineering level person, and after going thru some stuff with my network they admit that there is a problem with their firmware but as of yet no update was released.
    This was about 5 weeks ago.

    I really like the stat. It seems to regulate fine but the problem is using an app or computer browser that it shows the stats OFFLINE and can't communicate with it. It might be in this state for 5 minutes or 25 minutes. Eventually it comes back ONLINE.

    I'm in a holding pattern now but if not fixed soon I'll go to another brand thermostat.

    Looks awesome. Worked Great for 3 months. Then Epic Failure.

    • Written by from Arlington Heights

    After 3 months of impressive performance, my family went away on a three day vacation. On the way back and about an hour away from returning home, we tried to turn the heat up so we could arrive to a warm home. The setting was on "away." When we tried to turn the heat up, we got a message saying that the last time the unit was "on line" was two days ago. We were disappointed that we could not warm up the house but that was the least our problems. After assuring my wife that the Nest would just maintain the preset "Away" temperature, we were shocked to arrive at a house that was 43 degrees F ! The weekend had been cold. It never got above 20 degrees and the over night temperatures were in the single digits...I have a separate thermometer in the house that records low and hi temps as well as the current temp and I confirmed the house had gotten as cold as 34 degrees! Half of our houseplants looked dead and our upstairs bathroom had frozen pipes! Nest support was responsive once the 20 minute wait to get to a live person was experienced. After several trouble shooting recommendations, we were able to get our heat working by tricking the Nest into believing the AC was the heat source. So the problem was our base. Nest promised to send us a new one immediately but seriously, this product, while nearly there in terms of functionality, design, and ease of use; is not ready for prime time. A device this importance needs redundancy protections built in. IT CANNOT change settings preset by the owner. END OF STORY. No excuses please. Make a device more reliable, not less reliable, that the unit being replaced. It took more than 12 hours to heat our home back to a normal temperature. Imagine if we had been gone for a week or more???? This was a horrible experience I don't wish on anyone. I reinstalled the old thermostat. Bummer but at least it works.

    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.

    Can't hold comfortable setting

    • Written by from Bothell

    It looks good and the remote interface isn't bad but, but it allows the temperature to swing almost 2 degrees in either direction of the set temperature. This leaves you feeling too hot or too cold most of the time. It also make the set and forget ability of a programmable thermostat useless because you have to constantly adjust it. Going back to my ugly, no remote interface Honeywell.

    Monitored My Home From 1,800 Miles Away

    • Written by from Carman

    Spent the winter in Arizona and monitored my home's temperature in Carman, MB via iPhone, iPad and a PC. Great! Still can't believe they haven't built in a notice system that would send an email if furnace fails to start on demand and temperature drops. Given that one's login credentials include the email address, it seems like the infrastructure is all there. Someone just needs to activate it.

    Love this!

    • Written by from Kansas city

    I installed the nest myself and had no problems. Our home is fairly new so all of the wires were the right ones. I had a few questions and the Nest customer service was great! I love being able to control our thermostat when I am not at home. We aren't going to use the setting where it learns our home and away from home pattern because we have crazy schedules and its never the same.

    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.
