The best smart thermostats
- A smart thermostat automates a home's heating and cooling systems for optimal comfort while helping save money and energy.
- You can control a smart thermostat on a system panel, through an app, or even a voice assistant.
- Our smart thermostat recommendations are easy to install, help a home climate system operate efficiently, and effortless to operate.
- The Google Nest Thermostat E is our top pick for the best smart thermostat because it uses artificial intelligence (AI) to optimize your schedule, has an eco mode with geofencing, and is supported by an excellent app.
According to the United States Energy Information Administration, space heating and air conditioning make up more than half of the average home's energy consumption. If you're looking to cut down on your heating and cooling costs, a smart thermostat is a solution.
The latest smart thermostats include features like remote sensors, geofencing, AI machine learning, automation, scheduling, and much more. Because they can run your home's climate systems (heating, ventilation, and air conditioning, or HVAC) more efficiently, there's a sustainability factor as well. Our guide recommends models that are a breeze to install, could help increase energy savings, and are effortless to operate whether manually, using an app, or over voice control.When we examined each model, we considered its smart features, automation capabilities, and capacity for energy savings. We also noted how easy they are to install and operate. We explain our testing and research procedures in more detail as well as other models we looked at that didn't make the cut.
