It’s been nearly 10 years since the first Nest Learning Thermostat was released. If you ask me, a refresh to the lineup was long overdue. Not that the 2020 Nest Thermostat is revolutionary by any means, but the device’s new design and cheap price point make this an overall more approachable smart home device — particularly for those who are new to smart thermostats.

Read our full Google Nest Thermostat review to see if it’s right for you.

About this Google Nest Thermostat review: I used the Google Nest Thermostat for one week in my home in Rockford, Illinois, running software version 1.0-16.

Google Nest Thermostat: What’s new?

The main differences between the new and old models are in design and in Google’s cost-cutting measures. To be clear, the Nest Thermostat isn’t replacing the Learning Thermostat. Instead, it’s the go-to affordable option now that Google is transitioning the Thermostat E to professional-only installs.

Design and display

Despite being made of traditionally “cheaper” materials, I prefer the look of the new Nest Thermostat. The housing is made of plastic and it has a nice mirror-like finish on the front. Through that “mirror glass lens,” you’ll find a 2.4-inch color LCD display with a resolution of 240 x 320. You can see the square cutout of the display at certain angles, but looking at it head-on you’ll only see the mirror finish. I love the way it looks.

What I don’t love is the fact that it now only shows your home’s temperature and not the time. I suppose this is more in-line with other traditional thermostats out there, but it would’ve been nice to have access to a clock in that pretty display.

This is likely the prettiest smart thermostat you can buy.

Previous Nest models had you rotate the housing to adjust temperature and scroll through menus, while a push in would act as your select button. The new Nest Thermostat only has a touch-sensitive panel on the right side to adjust temperature. Tapping anywhere on the right side will act as the select button.

I never ran into issues with navigating around the thermostat or changing temperature. Though, I also never owned the original Nest Learning Thermostat, which seems like it would be more intuitive to control.

You cannot create or edit temperature schedules directly on the Nest Thermostat like you can on the Learning Thermostat. I doubt many people use their Learning Thermostats to create full schedules anyway. Just know that you’ll need to edit all your schedules in the app, and that your thermostat needs to be connected to Wi-Fi to receive those schedule changes.

You’ll notice my Nest Thermostat has a nice trim plate behind the unit. Unlike other Nest Thermostats, the 2020 model doesn’t come with one in the box. I needed to purchase this separately for $15 from the Google Store, but they’re also available from other retailers like Best Buy. This is an obvious cost-cutting measure on Google’s part.

Presence sensing

Remember that Soli radar tech Google used in the Pixel 4 for gesture and presence sensing? It may not be in the Pixel 5, but the company included it in the new Nest Thermostat. It uses its low-power radar tech to sense when you’re near it. It’ll show the display when you’re near and turn off the display when you’re not. This is similar to older Nest Thermostats’ Farsight feature that would light up the display when it sensed you walked into the room.

In practice, this is a nice way for the thermostat to show you details when you need them and save power when you don’t.

Close proximity sensing isn’t the only way Soli is used here. Combined with its onboard sensors and your phone’s geofencing data, the Nest Thermostat will be able to detect if you are or aren’t home. If it doesn’t sense anyone in your home, the thermostat will drop its settings down to Eco mode in hopes to save you some energy. Older Nest Thermostats also do this, but the new model is the only one to use Soli radar tech alongside your phone’s location parameters.

Google Home app and smart monitoring features

One of the bigger changes with this year’s thermostat is its companion app. It now hooks up to the Google Home app instead of the Nest app. We kind of knew this change was coming. You control Google’s smart home products with the Home app anyway, so it makes sense to have your thermostat controls there too. No need to hook up your Nest account through the Google Home app.

As far as I can tell, there’s no way to use the Nest app instead of the Google Home app. If your home uses other Nest products that are only compatible with the Nest app, you’ll now need to use both apps simultaneously to control your various Nest devices.

This also means you get more seamless integration with Google Assistant and Amazon Alexa. It’s not new, but being able to ask your smart speaker to set a certain temperature is super convenient.

During the setup process, the Google Home app walks you through a feature called Quick Schedule. This lets you set custom temperatures at different times on each day of the week. You set your preferred heating and cooling temperatures for Comfort, Eco, and Sleep profiles, and the app creates a schedule for you based on what it thinks you might like. You can change these times and profiles around as you wish.

This differs a bit from the Nest Learning Thermostat. That model learns from your usage and adjusts your temperature based on your habits over time. The Nest Thermostat does not. You create schedules in the app and change them throughout the day if need be, but it doesn’t do much learning based on your habits. It will, however, still suggest little tweaks in your schedule where it thinks you can save some energy. Nothing really happens automatically, though. Those new to the smart thermostat market (hello!) will probably be fine with this, but those coming from older, “smarter” thermostats might take issue.

On the subject of temperature control, the new thermostat does not support external temperature sensors. That means it only records temperature from the unit itself. If you have a big house or your second floor doesn’t get warm enough in the winter, this may be an issue. This is where the Learning Thermostat and Thermostat E really have a leg up on the new model.

Google’s temperature sensors are only available in select regions, so this may not be a big downside if you live outside North America.

Google introduced a suite of HVAC monitoring features with the new Nest Thermostat. Since HVAC issues can be quite expensive for homeowners, these might really come in handy. Your Nest will alert you if it senses something’s off with your system, like if it’s taking longer than normal to cool your home or if your furnace shuts off when it shouldn’t. It’ll also tell you when to replace your air filter. From there, you can either call an HVAC technician of your choosing or go through Google’s partner Handy to set up an appointment.

HVAC monitoring rolled out in late October to the Nest Thermostat, Learning Thermostat, and Thermostat E. It’s only available in the US and parts of Canada for now and requires a forced air system.

The installation process really couldn’t be any easier. Google says it takes about 30 minutes to install on your own, but there are options to get a professional to install it for $99.99. I went the former route to save some cash. Overall, the process took about 30-45 minutes minus the time it took me to fill some holes left by my old thermostat.

The easiest way to set up your thermostat is through the Google Home app. Hit the + button, select “set up device,” then select the “thermostat” option. After scanning a QR code on the back of your thermostat, you’re ready to install. The Google Home app does a lovely job of walking you through the process step by step. If you need more assistance, Google has help pages and video walkthroughs as well.

I won’t walk you through the entire setup process, but here are a few things I learned from going through the process myself.

First and foremost, be sure to check Nest’s compatibility website before you go buying a thermostat for yourself. My colleague C. Scott Brown found out the hard way that his system doesn’t have a common wire (or “C wire”), so he couldn’t use the new Nest Thermostat. My system had a C wire available but it wasn’t hooked up. Yet, the Google Home app gave me zero issue during the setup process. Hooking up the C wire would be a safer bet, according to Google’s website, but apparently it’s not something I need.

Can you tell I’m not an electrician?

The new Nest Thermostat supports up to six wires while the Nest Learning Thermostat supports up to 10. That’s likely where the 85-95{2d266c2b7f7b21b9d5247541775384085ff4c78fbe34d1f6195ea0b207eacd24} compatibility discrepancy takes place. If your system has more than six wires, you may need to look into the Learning Thermostat instead of the new hotness.

Once you know your house is compatible with a Nest device you can get started. Turn off the power at the breaker box, remove your old thermostat, and make sure to take photos of the wiring so you can refer back to it later. This is super important. My wires weren’t labeled before I set up the Nest and referring back to a photo of the old setup was extremely helpful.

The only other part of the process I remotely struggled with was mounting the base plate to my wall. The previous owners of the house didn’t think it was necessary to install the old thermostat in a neat way, so I had some holes to patch before I continued. No big deal. I actually ordered the trim plate after I found out the wall was a mess. I might recommend ordering one just in case and returning it if you don’t need it.

Price and competition

The price is one of the main reasons I purchased a unit for myself. It’s available outright for $129.99 from the Google Store, Best Buy, Home Depot, and other retailers. However, since this thermostat (like all other Nests) is Energy Star certified, your energy company will likely offer an instant rebate with your purchase. My energy provider offered a $75 rebate with new Nest Thermostat purchases, so I only needed to pay $55.

Google Nest Thermostat A cheaper, better looking thermostat

Google’s new Nest Thermostat is affordable, attractive, and works with 85{2d266c2b7f7b21b9d5247541775384085ff4c78fbe34d1f6195ea0b207eacd24} of home HVAC systems. It’s not the smartest thermostat you can buy, but it’s probably the best option for those new to the smart home ecosystem.

The new Nest Thermostat is meant to live alongside the third-gen Learning Thermostat, which is still sitting at $250. Now that the Thermostat E — Google’s previously cheapest option — is available for professional installs only, the new model is the easiest way to get a Google-made smart thermostat in your home.

But there are other competitors to keep in mind. The new Nest Thermostat slightly undercuts the $170 Ecobee 3 Lite, which is growing a little long in the tooth at this point. Ecobee’s $250 flagship Smart Thermostat is smarter and comes with a remote sensor, but it’s not really in the same price range. Although, you do get onboard Amazon Alexa support with that option.

It’s also more affordable, smarter, and a hell of a lot better looking than the $150 Honeywell Home T5 Plus thermostat.

Google Nest Thermostat review: The verdict

It’s clear by the Nest Thermostat’s feature set and new aesthetics that Google wants this to be the smart thermostat for everyone. It’s cheap, pretty, and works with most systems. Like most Google products this year (Pixel 5, Nest Audio, Chromecast with Google TV), the Nest Thermostat is approachable and won’t break the bank. It’s perfect for someone who wants to get going on their smart home or for someone who just wants something a little less tacky than other smart thermostats.

The Nest Thermostat is perfect for those new to the smart home.

There are downsides. The lack of support for external temperature sensors is the big one, and I’m surprised there aren’t more “learning” features like you get with older Nest models.

And although the $130 price tag is nice, smart thermostats are meant to save you money. They’re entirely worth the investment and will likely pay for themselves over a few years’ time. Thus, it’s difficult to say whether or not you should spend your money here or on the Learning Thermostat. If you can get a decent rebate and have the extra cash to spend on the higher-end model, it might be worth it.

But if Google’s latest and greatest is what you want, you’ll be getting a nice-looking, perfectly capable — albeit a little basic — smart thermostat on the cheap.
