Customer Reviews for Nest 2nd Generation 7-Day Learning Wi-Fi Programable Thermostat, Refurbished

We received our first nest thermostat through our electric service provider. Prior to receiving the nest, I visited the nest website to verify our system would be compatible. While there, I read that many, like me have programmable thermostats but never bothered to program them. Nest estimated waste in power consumption of over 20% by not programming the thermostat. I never programmed ours because I did not want to invest the time it would take to program the thermostat. Once I installed the nest it was fun to notice that every time we altered the temperature, it remembered our preferences. Within a week it had programmed itself to our likes. When we were not home, the "away" feature would adjust the thermostat to my preset temperature low for heat and high for the AC. I have since replaced the other two thermostats in our home with a nest. I highly recommend the nest and feel it is the best thermostat I have ever owned. Buy one and I believe you will agree.

So easy to use and very helpful with telling your what temps are eco friendly based on local weather report.

We have been using it for just over a month now and we are so glad we broke down and bought it. Pros: Easy to install, good visuals online. Works as advertised, Nest was learning our preferred temps after just a few days. You can control from iphone/ipad. Cons: Wish they provided a stainless steel wall plate to go with the modern look of the thermostat itself.

I have purchased 3 of the Nest Thermostat devices. They are incredibly cool and work like a charm. I have two more thermostats to change out, yes I have 5 zones but @$250 a pop I have been installing them every other week. Be warned it get's a little complicated when you have a heat pump thermostat with 7 wires versus the regular thermostat with 3 or 4 wires. I learned this hard way! Make sure you kill the power to the thermostat. I blew a 5 amp fuse on the heat pump furnace blower. I called Ness Support and I got to speak to their lead engineer - absolutely an amazing experience!!!! I like that that I can control the temperature/zones from my phone. I plan on buying two more Nest Thermostats for my last two zones. The learning algorithm is pretty cool, after 4 days it had learned my family schedule and was going to away mode, this is great saving energy and my money! However, with the crazy weather lately in Atlanta it was a little aggressive with the away mode since my boys were home from school and I had to go to the device/phone and remove some of the leanings that the learning algorithm had implemented. In summary - it is a sleek design, the packaging reminds me of the iPhone packaging and the overall ease of install/use it simply elegant!

This product is very easy to install, control and use. I have seen a significant decrease in my energy use.

Was looking for a simple automated Thermostat and found one in the Nest Learning Thermostat. It expertly managed the Polar Vortex of '14 in it's first week! I coupled it with the Nest Protect Smoke and CO detector. Took all of 15 minutes to install both units and connect to the Home WiFi and internet! Simplicity at its best!

I've been using the nest for approximately 30 days now. The design of the unit is exceptional and it would be at home in any decor. Construction of the unit is also excellent. Nest chose to use metal and glass as opposed to the cheaper plastic materials found on most thermostats. I am extremely pleased with the design and construction of the product. The function of the Nest is marginal for a product that demands the price premium this one does. The proximity sensor (used to sense when you approach) is flaky at best. Sometimes walking by the thermostat will make it light up just as intended. Other times standing in front of the thermostat madly waving your arms has no effect. This would be a minor annoyance but for the fact that when it's not responsive, the thermostat automatically enters "away" mode and turns the heat down to 60 degrees. I have been forced to disable the "auto away" mode because of this ongoing malfunction. Multiple resets and calls to support have done nothing to correct this issue that many users are seeing. I operate a dual fuel system and have caught the system running the wrong unit based on temperature three times in the last thirty days. Calls to Nest regarding this have not been helpful. On the first call I got "level one" support that didn't appear to know how a dual fuel system works. Had I not been better informed than he, they would have had me change settings in the unit essentially wiping out any efficiency realized from having the dual fuel system. The "level two" support at least understood my problem, but still did not have any insight as to why the problems were occurring. I have not had this malfunction in the last two weeks. The web based control portion of the thermostat is exceptional. It is extremely intuitive and easy to use. If you disable many of the other functions and simply use this as a remotely controllable thermostat, you will not be disappointed. Unfortunately, there are many cheaper alternatives if this is all you're looking for. Overall I like the Nest appearance and web function. There appear to be issues with sensors and logic that need to be fixed.

This is the most beautiful thermostat I have ever seen. The fit and finish are entirely beyond the competition at the same price point, and the learning and reporting features are a real bonus. I only had two complaints: the first unit's internal battery would not hold a charge and would shut down daily. I charged it off the wall with a phone charger until my replacement unit arrived in the mail. My second and final complaint is the misalignment of the replacement unit with the existing base pin connector (they only sent a new faceplate without a matched base). So it wouldn't work at all. So I took it back and now I have a less interesting but completely reliable competitor unit.

Installed the Nest Thermostat this weekend and it pushed our heat up to 80 degrees no matter how low we programmed it to go. It is 40 degrees outside. So we called Tech Support and they told us to keep it set to 80. When we told them we couldn't live in a house that was that hot, they advised us to turn it off. Did I seriously pay $250 for a product they advised us NOT to use? One hour and a half later tech support could not resolve the issue. They don't know what's wrong. We are reinstalling our cheap olde programmable one that always worked well. DOn't waste your time or your money - it is NOT what they promise.

I own this product and have used it since January 2013, in winter and summer. It is great. My electric bill has gone down $28 per month and my heating (gas) bill down $12 per month. I have an Android app to run this and they are continually updating the software. Not only a great product, but great looking too.

This thermostat was easy to install. I ran into a small issue during installation and I called the people at NEST and I got a live body and he was very helpful. I had a blown fuse in my furnace, replaced the fuse and the NEST was up and running. I had just installed an air conditioner a month prior and I got my power bill, I about fainted. The next month which was hotter I got my power bill and using the NEST it saved $44.00. My family was comfortable. This is a great product.

The NEST was a bit painful to teach as it wants to save you money by making it warmer in the house, but once it figured out our patterns, it's been hands off and has worked out for us quite well. We had to disable auto-away feature because it would turn the AC off when it thought we were away for more than 4 hours. Unfortunately that meant coming into a hot house and waiting a few hours for it to cool back down. Still would recommend it.

The Nest thermostat takes the guess work out of programming. Initial setup has you manually change your thermostat over the first week or so, after which the thermostat learns your habits and starts to set itself. I found the thermostat very easy to install, simply connect the wires to the corresponding terminals and the nest detected them and automatically set itself for my heating and cooling type. Motion sensors are built in, so it knows if you are away and automatically sets itself to conserve energy. This worked very well for us. I returned home early one day and the Nest sprang to life and cooled the home. Some features not found in a regular thermostat are the "Airwave" feature. Typically thermostats stop the fan when the heating or cooling is stopped, this leaves some hot or cold air in the ducts. The Nest runs the fan a little afterwards, pushing out this otherwise wasted air. The Nest also learns how long it takes to heat or cool your room. So when you select your desired temperature it tells you how long it is going to take to get there, this actually influences your choice and can result in energy savings; for example I told the Nest I wanted to cool to 75 degrees and it said it would take 44 minutes to get there, selecting 76 told me just 20 minutes. I picked 75 instead and saved 24 minutes of energy (I didn't notice the 1 degree difference). The Nest tries to influence your energy use habits. If you pick an energy efficient setting it shows a little green leaf on the display, this actually influenced me to pick a smarter temperature, saving me money and energy usage. Aesthetically the Nest is a work of art. Very futuristic, yet not too obvious. The color display and solid metal casing make this stand out against the traditional plastic offerings. The polished black display spring to a vibrant colorful display when you approach, and also when you make changes using the free mobile application. A helpful install kit, including tools, is provided. As is a concierge service to help with installation issues. I cant comment on the latter, as I didn't need to call - it was so easy to install. I used this with an iPhone app, and I was surprised as how quickly it responded. I've used mobile applications with other WiFi thermostats and there is always a little lag, this seemed to respond immediately. The thermostat can be controlled manually, via a web site, or using a smart phone. Filter change emails can be configured too - these are smart alerts. The Nest alerts you based on usage, not on how long the filter has been installed. If you don't need to run your AC or heating for a while, the Nest knows the filter is not getting dirty and doesn't tell you to change it unnecessarily, conversely if you are using it a lot it knows you need to change it more often. Energy usage is available on the web and smart phone, along with information on how you compare to other users in your area. You'll find yourself trying to save energy to get in the top bracket of low energy users.

Best aspect of this device is the external service nest provides to monitor and report on the energy usage. If you could benefit from the benefits of a programmable thermostat then this one will make the programming effortless. However if you have consistent occupancy then the away function may not save much in energy. But you preferences for temperature can be accomodated easily. Little noted feature is the integration of local weather and sunshine to regulate HVAC usage as well as indoor humidity. I assume this is via a hydrometer internal to the thermostat. Installation literally took 10 mins given that I didn't need to use any of the installed wall covers for holes.

This product helps the world because it reduces the energy consumption at a house level. I love the fact that I can control the nest from anywhere as long as I have my phone. I was very happy that if i'm cold or hot I can touch my phone and control it from anywhere in the house to the comfort level. I'm also thrilled by the fact that it keeps track of all the temperature levels that are comfortable for the family and it can save us a lot of money for the years to come. It is a quality product, and it looks great in our dining room. it is SO EASY TO USE!!!

The Nest Thermostat is a big step to making your house smart. You can quickly access energy reports from your laptop/smartphone/tablet, control the heating/cooling, and much more! Installation was too easy. Following the manual, taking pictures of your wires, and giving the wire labeling information to their website, are essential to this part of the process. In turn, the website will tell you whether your system is compatible with Nest, and where each wire will go on the wiring component for the thermostat. Nest really does an awesome job holding your hand on this step! If you're having trouble, don't hesitate to call their support. The product also includes a screwdriver with magnetic bit, handy for simple jobs around the house even after you're done with this step! The setup and functionality of the device is intuitive and terrific. It takes you step-by-step, from confirming what kind of unit you have, to the wiring, to the wi-fi, to updating the device and getting itself ready to amaze you. After it is done, you can sit back and relax while it learns your habits, or you can dive right in on the website and schedule and control what the Nest should do, and when. Personally, I like to be in control, and I don't really like the "learning" and "auto-scheduling" the Nest involves. If you are like me, though, you are more interested in the savings behind the device. And the savings is definitely there! If you let the Nest auto-schedule and learn what your habits are, you are risking the true potential savings in the device. By manually scheduling, you are in control. By the next day, you can review your energy report and see exactly when your unit was on, and for how long. You can also see what temperatures were set by you or someone else throughout the day. Talk about 1984! By utilizing the energy report on a day-to-day basis you can learn from your own behavior and how to find that savings. It lights up when you walk across the unit and shows you the temperature the thermostat is set on, and what temperature the house is at. After a couple weeks, when it is cooling or heating, it will tell you how long it will take to get to the required set temperature. Cool! My wife called me one day to tell me it was 89 degrees inside the house; she thought I was trying to kill her! I checked the Nest online and saw where the problem was, and quickly fixed it. Being able to control the Nest from wherever you are really gives you that sense of awareness and control. Overall I am very impressed with this thermostat. It is so simple and easy to use, and neighbors are always marvelling and asking what in the world it is! It's very smart, and it will help save you money in the long run, just compare your last year's energy report to this next one with the Nest, and you will see! Nest is always updating its device with newer features, and it has a lot of potential to do even more!

When I first unpackaged the Nest, I quickly realized that Nest makes this really easy for you. They even provide you with labels for your wires, so you can keep track of everything. In addition to that they give you a tool (which i'm adding to my tool box) to use for installation. The directions were great and it took me about 15 minutes to completely install (I'm an average DIYer). Not only do you have a great machine, but you can control it via an APP on your phone which shows you how much energy you are using. Overall this is a top notch product that provides better insight to your HVAC activity.

Starting with the installation - There were a couple of connection labels on my old thermostat that I wasn't sure about so I called the Nest help line. The wait was less than one minute and the tech support was absolutely the best. Answered my questions and I installed the thermostat in about 15 minutes. After installation the thermostat guides you through the setup in a question and answer format. That process took just a couple of minutes. Controls cooling temperature very well and displays set point and actual temperature when you walk in front of it. There is a menu to select cooling, heating, etc that is user friendly and easy to navigate. The technology packed in this thermostat is amazing. Hooks up to your Wi Fi for control from a smart phone or PC although I haven't tried that feature yet. The display lights up when you walk in front of it with nice large and easy to read numbers. It seems expensive until you see all of the technology built in to the device and with our mobile society it fits in perfectly.

I have used several programmable thermostats over the past 20 years and have always gone back to a simple thermostat because of the difficulty in making adjustment. This new Nest Thermostat takes “Ease of Use” to another level. No rigid daily schedules to program, and it uses a motion sensor to learn your daily schedule after a few weeks. The Installation Instructions for the Nest Thermostat are very thorough and easy to follow, and all necessary tools and adapter plates are included. The initial setup took only a few minutes and the thermostat automatically found my wireless router and requested the network password. It also generated a code for setting up an account at Nest.com to access and control the thermostat via the internet. I especially like the energy management function, which shows the time your HVAC unit operates each day. You can clearly see the energy consumption impacts from adjusting the temperature setting and different weather patterns. The longer I own this thermostat the better I like it. The build quality is superb and the ease of use and functionality are excellent. Highly recommend this new state of the art thermostat.

I heard about the NEST Thermostat and how it can cut energy spending in the home. I saw their website and promo video and was instantly hooked! Cracking open the box, I found all the pieces to be made with exquisite precision. The design is whimsical and intelligent, yet modern and chic all at the same time. This device is more than a thermostat, it elevates my living room and home to a "Jetsonesque" level! All the tools to install were included. NEST even included a wall plate to cover up the size difference from the previous unit that it is replacing. This kept my wall clean and eliminated the need to waste time prepping and painting. VERY SMART! After installing the wall plate and tagging the wires with the supplied identifier stickers, I installed the wiring harness with 2 screws and clicked in the system wires. I snapped in the NEST bezel and turned on the power! "IT'S AAAAALIVE!" (We giggled with fascination and gawked at how beautiful it really is!) The manual setup was easy and thorough. My WiFi connection synced and I was able to install the app on my iPhone 5. SO EASY and FUN! Please watch my video and see how fun and easy it is to REVOLUTIONIZE YOU HOME HEATING AND COOLING! Happy Thermo-regulating!

Of the number of programmable thermostats I've owned, this one was the easiest to install, and configure. It took me longer to patch, sand, and paint the holes and scuffs left from the old thermostat than to program this one. I could have used the supplied back plate to hide the holes and scuffs, but I wanted the look of just the dial. Once installed and power turned back on, it discovered my home network and connection was a breeze. With an established connection, the thermostat downloaded and installed some updates. Following that it displayed my location, temp, time, and humidity. I was then prompted to set my low and high temps. I have an Android App on my phone for the Nest, and when I went into the App, I was prompted to go into my online Nest account and confirm the addition of my thermostat to my account. From there, I set up my schedule for weekends and weekdays, etc. Overall, I love this thermostat. Start to finish, it took me about 2 hours to complete everything...To include patching the screw holes and painting. Throughout the week as the Nest learns our house living patterns, I'll keep an eye on the temp as the temperature we normally keep our house at during the summer is all-of-a-sudden too cold. The Nest is indicating our house is 76 degrees however, I'm not sure it's that hot but, it's also a much better thermometer within the thermostat so I'll have to adjust the schedule temps. Extremely great build quality, functionality, and appearance.

Let me start by saying I was very skeptical of the Nest thermostat before I finally bought one. However, Nest's ability to respond to dynamic situations is ultimately what made me buy it. My wife is a nurse who does not work a regular schedule and we live a pretty dynamic life. This meant a typical programming thermostat would be difficult to use effectively. Nest, on the other hand, has an auto-away mode which detects a lack of motion for a period of time and switches to a less energy intensive cooling mode. It also handles on-the-fly changes really well. Setting the schedule is a breeze using an iPhone or the web interface on your computer. Installation was really easy as well. The wire-terminal ring is genius and could not be easier to use. I do think the 1st generation Nest is a little bulky so the 2nd generation model is suggested. If you have an older or larger thermostat, you will likely find a pretty rough looking area of wall behind it when your go to install your nest. Nest tries to help by providing you several backing plates to cover up un-painted or ugly wall, however, I would suggest painting the area and not using the cover plates as I do not like the look. I did not have any problem with wifi hookup as the instructions were nice and simple.

Neat product. Easy to install. 10-15 minutes. Works great with Iphone.

We have to keep taking the thermostat off the wall and manually charge it. The battery keeps going dead on the wall and will not recharge. Very annoying - I wish we had not purchased this thermostat.

Works great and easy to install if you have basic wiring skills.

Awesome device

Really does more than I need. I wanted to do 2 things: 1. Allow anyone to adjust the thermostat as long as they didn't try and set cooling below 72 degrees. This thermostat allows that and has a password lock to ensure that no one can put the cooling temp below 72. 2. Control remotely.
