Rated 1.0 out of 5.0 by MikeDinGurnee Beware of these....
I had 2 of these installed for just over a year and a half. Numerous back plate failures and added repair costs forced me to remove these and find an alternative. (Ecobee) My HVAC equipment is the most basic and common- single stage, forced air heat and AC. I do have the notorious "C" wire for powering these units. Since the firmware update in Nov. 2014, they went offline much more often, which defeats the purpose of these when controlling remotely. If you're considering, do extensive research regarding failed FET backplates and the offline issues. $1500 spent for me that I'll never recover. Beware!

Rated 5.0 out of 5.0 by PopKim Everything I Wanted
The Nest takes time to adjust to your house and habits before it can fully utilize all the features it comes with. I've been using Nest for nearly three months, which is enough time for everything to adjust and work perfectly, but honestly, from day one I was happy with my purchase. There are loads of things I love about this device so far, so I'll focus on the highlights.
The device was simple to install with very clear instructions, it even came with the nicest screws I've ever seen to install it with, which was kind of hilarious but a nice touch. A small bubble level is on the base of the device to help when mounting it to the wall. While my last thermostat had me screw in the wires to keep them in place, Nest features a little snap/clamp thing where you just need to press the button where the wire goes, slide in the wire, and release. Done. The whole device pops into place easily and even walks you through the account set up once it receives power. It came with a white rectangular faceplate at the bottom of the box which covers up the old holes from my last thermostat. This was a great edition because on one hand I love the sleek design of Nest, but since my last thermostat was a different shape, holes were going to be left in my wall. This nicely covered it up and left the area looking sharp.
The device has a very sturdy design with glass and metal that will last probably forever. The screen turns off when not in use and will momentarily light up when something changes, like it if it turning on the AC. When you want to view the current temperature, you can just wave your hand close to the motion sensor or tap the bottom section of the circle to make the screen turn on.
Nest does a very good job at learning your habits through a combination of using a motion sensor, light sensor, and your own manual adjustments to the temperature. Whenever I get home and walk by the thermostat, I hear my AC automatically turn on, which is exactly what I expect. I'm also easily able to access the Nest through an app on my phone, which means I rarely need to even touch the device. While the app has a myriad of features, my two favorites are the schedule and the energy history. There was a week where I was awake and working late every night and Nest noticed and made the AC turn on late at night when I was up. Afterward, I was easily able to click the timed event on the app and delete it. Extremely simple.
The energy history feature on the app tells you every single time the Nest turned on the air and for how long. It also told me what the reason was if the AC was used more than normal, for example, it would say user adjustment or high or low weather. I also receive monthly emails about my energy usage.
I love that the Nest takes into account when my house is in direct sunlight and what my local temperature. The little green "eco" leaf tells me what is the most energy efficient temperature for the circumstances. It doesn't always show up on the same temperature because conditions change that effect it's formula, which makes it easier for me to not think about it and trust my device to make things simpler.
All in all, this is exactly what I expected from the device, and I was pleasantly surprised to get even more features than I originally thought. I installed it quickly, it started learning immediately, and has done a good job at saving me money already and paying for itself. I highly recommend this if your looking for a quick fix that will give you one less thing to worry about.

Rated 5.0 out of 5.0 by TimCPI A slick and money-saving device, fun to use.
The NEST thermostat was easy to install and actually fun to program. I did half of the initial programming on the device itself, the other half over the Internet with my laptop. It is also easy to override your settings at any time from your smart phone with the free iPhone app. I expect to save a fair amount of fuel oil because of this device and I recommend it highly.

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 a smart phone 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.

Rated 3.0 out of 5.0 by Murr Mixed Review
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.

Rated 1.0 out of 5.0 by Annunca Frozen AC lines and damage to contactor and condenser board
The Nest thermostat damaged two contactors and a condenser delay board and almost killed the AC condenser. Because the contactor was damaged and shut, the condenser was running without the blower causing the refrigerant suction line and condenser to ice up. After replacing the first damaged contactor, the Nest damaged the replacement contactor as well (permanently welded) and the time delay board causing the AC condenser to run continuously and causing the lines to freeze up again. In 20 years I have had this AC unit, I have replaced 4 thermostats and NEVER had I experienced the kind of problems and system malfunctions caused by the Nest thermostat.

Rated 4.0 out of 5.0 by OldDuffer This product does what it claims.
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.
