From the Manufacturer

Nest Learning Thermostat

Saving energy is a beautiful thing.

Meet the Nest Learning Thermostat. It learns from you and your home, programs itself automatically, and helps save energy when you’re away. And you can control it using your phone, tablet, or laptop.

Let’s stop wasting energy.

Your thermostat controls about half of your energy bill. That’s more than appliances, lighting, TVs, computers and stereos combined.

A lot of that energy is wasted heating and cooling an empty home. Programmable thermostats were supposed to help. But many people never program their thermostats – it’s just too complicated.

So Nest makes it simple by programming itself.


Just turn it up and turn it down. The Nest Thermostat learns the temperatures you like and creates a personalized schedule for your home.

Energy History:

See exactly how much heat or air conditioning you used in the last 10 days and why. The more you know, the more you can save.


Don’t heat or cool an empty home. After you leave the house, the Nest Thermostat senses you’re gone and automatically adjusts the temperature to save energy.

Nest Leaf:

Want to know if you’re saving energy? The Leaf appears when you select a temperature that’s energy efficient, guiding you in the right direction.

Remote control:

Use the Nest app to set the temperature, change your schedule or check your Energy History from your phone, tablet or laptop.


Save on your cooling bills. Airwave automatically runs the AC less when humidity in your home isn’t too high, while ensuring you stay cool.

Easy to install.

If you’re comfortable changing a light fixture, you can install the Nest Thermostat yourself. Four out of five customers install it in 30 minutes or less. Or a trained Nest Pro can take care of it for you. Visit to find one near you.

At home in most homes.

The Nest Learning Thermostat works with 95% of low-voltage heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar and geothermal.

I installed this last fall with a new 2-stage forced-air furnace. Worked great all winter. I love all the features, particularly the recent software upgrade that allows intermittent fan operation to circulate air. Worked for a while this summer but eventually the Y1(cooling) connector in the base failed. Tried a second one and it failed immediately. Nothing wrong with the furnace or A/C (had two different technicians check the equipment). Did a little research at the Nest website,and found out this is a pretty common problem. The Y1 connector can't handle the voltage. Nest won't admit there is a design flaw and it doesn't look like Nest will be providing redesigned bases. Too bad, I really like it and and will miss all those endearing features. It was great while it lasted but in the end it broke my heart.

Head unit works fine but unfortunately it is now just an expensive paperweight.

I was telling everyone who would listen about how much I loved my Nest. Then last month they 'pushed' it a software update related to their new (and misguided, in my opinion) Protect fire/CO2 alarm. Now my Nest's battery dies when it is connected to WiFi (the remote connection is the main reason I bought the thing) causing it to stop heating my home properly (or at all if I had let the battery die completely). It's -25 outside. I shudder to think what will happen the next time they push an update and I'm away from home and unable to fix it even after hours on hold for tech support and reading the forums looking for my own fix. For now WiFi is turned off while I see if they're going to get a fast update out to repair it, or if it's going in the skeet launcher as a clay-pigeon substitute.

If you're shopping this product I would highly recommend spending some serious time browsing the Nest Community forum. There are a lot of unhappy folk posting there right now.

Nest seems to think that crucial home products like thermostats and fire alarms are AOK to play with and to have rely on unstable updates and wireless connections. I was considering a Protect fire alarm until I discovered that it does not support a wired connection between alarms so that when one alarm activates they all do. They want to rely on a wireless connection, thereby ensuring that the Protect does not function with your existing units so that you have to replace them all. This is why I initially thought it was a misguided product. Now I am certain I will NEVER have one (as if I'm going to trust them with my life). They will get this one chance from me, if they fail to fix the T-stat fast and permanently I won't be trusting them with frozen water pipes in my home either.

I purchased this product a few years ago, the learning function was completely useless for me. I've disabled all of the extra functions an basically use it as an over priced programable thermostat. Controlling it through my phone works well, but the app is horrible to navigate.
The styling is nice but in the end for me it wasn't worth the $250 or so I paid.

Easy to install and use. I love being able to access and schedule my heating using an app or online. It looks very sharp in my living room and has very solid construction and feel when using.


Terrible, absolutely terrible, customer service. I almost gave up and was going to return the product. Nest broke my thermostat by an ill conceived firmware update. An update that was pushed to my thermostat without my consent and knowledge, which caused a low battery and network failure. I had to call and be placed on hold for 25 mins only to get a completely unapologetic person on the phone. I paid a lot of money for this product and Nest broke part of its basic functionality and I was told that it would take up to 2 to 3 weeks, yes weeks, for Nest to downgrade to the previous firmware. This seemed reasonable to the person on the phone. When I pushed him for a replacement thermostat, because after all it was Nest that broke it by pushing an update without my consent, Nest said it was impossible. Essentially they broke my thermostat and provided no recourse for their negligence.

I wonder what would have happened if their error had involved a loss of heating in my home? It's -35C where I live. They could have ruined by house through their negligence. Would I be left holding two wires together to turn my furnace on, while someone rushed to the hardware store for a replacement?

Ability to control it remotely is amazing. Auto-away function and seeing how much the furnace is running historically is great for conserving energy. Neat too that it can estimate how long it will take to get up to temperature.
Not all Canadian postal codes are set up in Weather Underground, where Nest gets its outdoor data, so weather isn't 100% accurate but it's close.

No intro needed for this unit.

Only issues I've been having is that it goes offline once and a while.

I have very strong WiFi... It's easy fixed when I walk up to the unit and press it.

It's annoying when I'm upstairs and want to turn on the AC with my phone though.

Executive Summary: Cool toy, but it might fail on you when you need it the most.

I bought this in April 2013 - it seemed to work fine, but then it was spring/summer and I didn't really use my furnace much. Then in October when it started getting cold I noticed my house temperature kept dropping. The nest was calling for heat, but my furnace wouldn't turn on (both house and furnace are brand new). I fiddled around with the nest and got it to work for one heating cycle by dropping the target temp below current temp (cancelling call for heat), then upping the target temp above current temp. It would work for one heating cycle then revert back to not working. This quickly got annoying. Soon after even this didn't work and the furnace would not come on. I called in my furnace company, and the tech said it was the nest. As a precaution, he swapped out the control circuit board with a new one, and away he went. Well a month later, I started having the same problem. Furnace tech came by again and blamed it on the nest. I took down the nest and put my old thermostat on and I haven't had any problems since.

On a side note, I browsed through the nest support forums, and several other people were having the same issue as me. Nest support staff didn't resolve their issue - they just asked them to give them a call. So I decided to give them a call to see what they had to say. I called a total of six times - each time the message said the wait was > 30 minutes to talk to someone; four times I hung up after waiting 10 minutes or so. One time I got through after waiting 45 minutes, only to have the rep not believe that it could be the nest that was causing the issue, then get abruptly disconnected from my call. Nest support wasn't very helpful.

Bottom line: it's a cool toy, but it's a glorified switch and one that they messed up by making it too fancy.
