10 Best Honeywell Thermostats 2025 in the United States

The Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat is an excellent choice for homeowners seeking a programmable and smart home compatible thermostat. One of its standout features is the customizable color touchscreen, which enhances usability and adds a modern touch to your decor. The seven-day programming capability allows users to tailor their heating and cooling schedules based on personal routines, which can lead to energy savings, especially during peak utility pricing times. Additionally, its integration with popular smart home systems like Alexa, Google Home, and SmartThings makes it an appealing option for those with existing smart home setups.

Another strength is the inclusion of energy reports and intelligent alerts, such as reminders for air filter changes, which can help maintain your HVAC system's efficiency. The Energy Star certification further assures users of its energy savings potential.

On the downside, some users may find the initial setup process a bit overwhelming, especially if they're new to smart devices. While the thermostat is designed for easy use, those less familiar with technology might require extra time to fully understand all its features. Additionally, while it offers great flexibility, the reliance on Wi-Fi means that any internet connectivity issues could hinder its functionality. In terms of design, while sleek and modern, it is crucial to ensure that it fits well with your home's aesthetic and existing decor. Finally, the one-year warranty might be seen as a bit limited for a product that serves such a critical function in your home.

The Honeywell Home RTH9600WF Smart Color Thermostat is a solid choice for homeowners wanting to upgrade to a smart thermostat with energy-saving features. It offers convenient programmability and remote control through a user-friendly app, compatible with popular voice assistants like Amazon Alexa, Google Assistant, and Microsoft Cortana. Its customizable touchscreen display adds a nice personal touch, allowing you to pick your preferred color and providing clear indoor/outdoor temperature and humidity info, plus weather updates right on the screen.

Energy savings are a highlight, thanks to its ENERGY STAR certification and smart tips that help you reduce usage. The ability to participate in utility demand response programs can also lead to extra savings if your local provider supports it. The thermostat works with most common heating and cooling systems, including gas, oil, electric furnaces, and heat pumps, but it requires a C-wire for power and is not compatible with electric baseboard heating or certain heating-only oil furnaces without a C-wire.

Installation might be a bit tricky if your home doesn’t have the necessary wiring, which is important to check beforehand. The device is designed to be intuitive, with touch controls and smart response technology that learns your preferences for comfort and efficiency. Its slim, modern design fits well in most homes and the 2-year warranty offers some peace of mind. While the need for a C-wire can limit compatibility in older homes and line voltage heating systems are not supported, this Honeywell model remains a reliable and attractive option for those with compatible systems seeking a smart thermostat that balances ease of use, energy savings, and smart home integration.

The Honeywell Home T9 WiFi Smart Thermostat stands out in the smart thermostat category for its programmability and advanced features. One of its key strengths is its ability to control temperatures in multiple rooms with the use of Smart Room Sensors, allowing for a customized comfort experience. The Auto Home/Away Scheduling feature helps save energy and money by adjusting temperatures based on your presence, which is especially beneficial for users looking to reduce their energy bills.

Its compatibility with various heating systems, including forced air and heat pumps, makes it a versatile choice for most homes, though it does require a C-wire or the included power adapter for low-voltage systems. The thermostat's ease of installation is a significant plus, making it accessible for DIY enthusiasts.

Potential buyers should be aware of a few drawbacks. The need for a C-wire can limit compatibility with some older setups, and it won't work with electric baseboard heating systems. Additionally, while the range of the Smart Room Sensors is impressive, the effectiveness can vary depending on home construction. The integration with popular smart home platforms like Amazon Alexa, Google Assistant, and Apple HomeKit adds to its appeal, providing users with seamless control through voice commands or mobile apps. The sleek design and touchscreen display also enhance its user experience, although some users might find it slightly challenging to navigate the app if they are not tech-savvy.

The Honeywell Home T9 is ideal for homeowners looking for a smart, energy-efficient solution that offers room-specific comfort, but it's essential to check compatibility with your current heating system before purchasing.
