10 Best Home Thermostats 2025 in the United States

The Google Nest Learning Thermostat - 3rd Gen stands out in the home thermostat category due to its advanced programmability and smart features. One of its main strengths is its ability to learn your schedule and preferred temperatures, which allows it to automatically adjust settings to save energy and enhance comfort. This self-learning capability is complemented by the Home/Away Assist feature, which ensures your home remains energy-efficient even when you're not there.

The thermostat is also user-friendly, with a high-resolution display that makes it easy to view current settings and energy history. Its compatibility with both Google Assistant and Amazon Alexa enhances convenience, allowing for voice control. Installation is typically straightforward, often completed within 30 minutes, and it works with 95% of heating and cooling systems, making it accessible for many households.

There are a few weaknesses to consider. While the thermostat boasts impressive features, some users may find the initial setup or navigation of its smart functions a bit complex if they are not tech-savvy. Also, the additional Nest Temperature Sensor, although helpful for achieving precise room temperatures, is sold separately, which adds to the cost if you wish to expand its capabilities. In terms of energy efficiency, the Nest Learning Thermostat excels by providing insights into energy usage and encouraging users to make more sustainable choices. However, it relies on Wi-Fi; any disruptions in your internet connection can impact its performance.

The ecobee New Smart Thermostat Enhanced offers significant benefits for homeowners looking to manage their heating and cooling costs efficiently. It is highly compatible with most 24VAC HVAC systems, making it versatile for various setups. The thermostat's programmability is a strong point, allowing it to automatically adjust temperatures based on whether you are home, away, or sleeping, ensuring comfort and energy savings.

The inclusion of smart features, like compatibility with Siri, Alexa, and Google Assistant, allows for easy voice control, and it can be managed remotely through the ecobee app on smartphones, tablets, and Apple Watches. This adds a layer of convenience for tech-savvy users and those new to smart home devices alike. The user interface is simple and intuitive, with a clear LCD display, making day-to-day usage straightforward.

Notably, the thermostat is ENERGY STAR certified and promises up to 26% savings on heating and cooling costs, which is appealing for those looking to reduce their energy bills and environmental impact. The installation process is designed to be user-friendly, with most people able to complete it in under 45 minutes, and it includes a power extender kit for homes without a C-wire. However, the need to purchase the SmartSensor separately might be a drawback for those wanting comprehensive room-by-room temperature monitoring from the start. Additionally, while the unit is hardwired, which eliminates the need for battery replacements, some users might find this a bit more complex during initial setup. Despite these minor cons, the ecobee New Smart Thermostat Enhanced stands out as a reliable and efficient choice for modern home temperature control.

The Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat offers a range of features that make it a strong choice for a home thermostat.

The programmability is flexible, with 7-day scheduling options that can be tailored to fit your home or business needs, and it includes features to adjust for daylight savings and different time formats.

The smart features are robust, offering intelligent alerts for maintenance reminders and temperature warnings, which can help in maintaining the system efficiently. The user interface is user-friendly, with a customizable color touchscreen that displays easy-to-read numbers and text, as well as local weather information and humidity levels. This makes it straightforward to manage and monitor your home’s temperature settings.

Energy efficiency is another plus, as it's Energy Star certified and offers demand response programs to optimize energy use based on utility peak rate pricing. Installation may require a bit of technical know-how, as it involves setting up with Wi-Fi and possibly integrating with other smart devices. However, the auto-updates and remote control capabilities via mobile devices add convenience. The Honeywell Home RTH9585WF1004 is well-suited for those looking to upgrade to a smart thermostat with comprehensive compatibility, ease of use, and energy-saving features, although some users might find installation a bit challenging without prior experience.
