The best smart thermostat deals happening now

We’ll be updating this page regularly to add the best smart thermostat deals available before, during, and even after Prime Day, so keep a lookout for any particular models that appeal to you.

What Prime Day smart thermostat deals to expect

Google Nest thermostat

We saw pretty much all the big brand-name smart thermostats go on sale during last year’s Prime Day blowout and we expect more or less the same this year. Keep your radar tuned for Prime Day smart thermostat deals on top makers like Google Nest, Ecobee, and Honeywell, which are arguably the “big three” names in this market. Some lesser-known models among the best smart thermostats include the Johnson Controls GLAS and the Cielo Breez, which are also great picks that should be on your list. All of these are available on Amazon and go on sale fairly regularly, so expect juicy discounts come Prime Day (as well as during the run-up to the sale).

What Prime Day smart thermostat deals we saw last year

In 2020, we saw a bundle of nice Prime Day smart thermostat deals on top models from brands like Google, Ecobee, Honeywell, and Emerson. There were some especially nice Nest thermostat deals for Prime Day 2020 (as well as for Black Friday, since the sales were so close together last year): The Nest Thermostat E saw discounts of more than 30%, with the best offers being bundle deals that included the thermostat with extra room sensors. Other specific models that saw nice markdowns included the Emerson Sensi and the EcoBee 4.

Should you buy a new smart thermostat on Prime Day?

Yes, you should, but don’t rush in blindly. We expect to see a lot of smart thermostats getting big discounts during Prime Day. That said, there are a few things to keep in mind while you shop. Always stick to household names; never buy your new smart thermostat from a brand you’ve never heard of before. Do some research beforehand and check which smart thermostats offer features that suit your particular needs. If you see a heavily discounted deal on any product, always check the reviews and ratings available before buying. If a deal looks suspicious or too good to be true — it probably is.

Also remember that not all Prime Day smart thermostat deals are going to be relegated to Amazon; many other retailers run their own sales concurrent with Prime Day to get in on the surge of online shopping action. Make sure you follow these tips to prevent buyer’s remorse while shopping these thermostat deals on Prime Day.
