If you live somewhere that's already feeling the extreme chill of winter, you know all about turning up the heat. But do you always remember to turn it back down when you're ready to leave the house? This isn't a test. We're human. We forget things. That's why a smart thermostat is such a great idea, especially one that you can control via app and set schedules for. Like the Google Nest smart thermostat, which is available right now for a great price.

As of Dec. 7, you can get the Google Nest smart thermostat for just $89.99, down from its normal price of $129.99. That's $40 off and a savings of 31%. It's also back down to its Prime Day and Black Friday price, so if you missed out on snagging one of these bad boys back during November's sale events, now's a great time to make sure you aren't left out in the cold again.

This programmable smart thermostat helps you save energy and money as you can set up a schedule and program it for when you'd like it to run via app. It'll also automatically turn itself down when you're away to make for a more efficient energy schedule. Then, control it from anywhere on your phone, laptop, tablet, or other mobile device. You don't even have to worry about keeping an eye out on your HVAC. The Nest will monitor it for you and send an alert if something seems amiss.

It's truly a remote solution for those among us who just don't want to keep getting up and changing what the thermostat is set to. It can be a pain, but if you can have the Nest do it for you, it becomes another one of those super simple home tasks you don't have to think about. Just keep in mind: for most homes, this thermostat connects without a C-wire, though you will need to confirm what type of setup you have before purchasing.
