10 Best Honeywell Heat Pump Thermostats 2026 in the United States

The Honeywell Home RTH9600WF Smart Color Thermostat is a feature-rich option for those looking to optimize their home heating and cooling systems. It is ENERGY STAR certified, helping users save energy and money while providing personalized tips for reducing energy use. Compatibility with various heating systems is broad, including forced air, hot water, steam, and heat pumps with electric backup, although it is not suitable for electric baseboard heating or heating-only oil furnace systems. The requirement for a C-Wire adapter is a notable consideration and may necessitate additional installation effort for some users.

Smart features are robust, with support for Amazon Alexa, Google Assistant, Microsoft Cortana, and more, allowing control from anywhere via an app or voice commands, making it a convenient choice for tech-savvy users. Programmability is flexible, offering both manual and automated options to maximize energy savings. The customizable color touchscreen enhances user experience by displaying indoor and outdoor temperatures, humidity levels, and weather forecasts, making it visually appealing and informative.

Installation might be slightly tricky due to the need for a C-Wire, but once set up, the thermostat provides comprehensive fan control options and smart response technology to adapt to user preferences. The Honeywell Home RTH9600WF is ideal for users looking for an energy-efficient, smart thermostat with advanced features and broad compatibility, with the caveat that installation requirements should be carefully checked beforehand.

The Honeywell Home T9 WiFi Smart Thermostat with 1 Smart Room Sensor offers various features that make it a strong contender in the heat pump thermostat category. Compatibility is a key strength, as it works with forced air (gas, oil, or electric), hot water and steam, and heat pumps with electric backup, though it does not support electric baseboard heat. Its programmability is notable with Auto Home/Away Scheduling, which can help save energy by adjusting settings based on whether you're home.

The thermostat also supports various smart features, including control through the Resideo app and compatibility with Amazon Alexa, Apple HomeKit, and Google Assistant, allowing for a flexible and convenient user experience. Honeywell's Smart Room Sensors enhance the system by focusing on comfort in specific rooms, with an impressive range of up to 200 feet, which is particularly useful in larger homes. Energy efficiency is emphasized, with an Energy Star certification and potential rebates from energy providers, aligning with its cost-saving promise.

The user interface is user-friendly with a touchscreen display, and the thermostat is relatively easy to install, with guided instructions and a power adapter for homes lacking a C-wire. However, there are some drawbacks. The need for a C-wire can complicate installation for homes without one, and the sensor batteries may require periodic replacement. Additionally, the thermostat doesn't support heating-only oil furnace systems without a C-wire, limiting its applicability in some scenarios.

The Honeywell Lyric T6 Pro thermostat is a solid choice if you have a heat pump system with up to 2 heat and 1 cool stages, or a conventional system with up to 2 heat and 2 cool stages. It requires a C-wire for power, so you’ll want to check your setup before buying. Programmability is flexible, offering options like geofencing and multiple schedule types (7-day, 5-2, 5-1-1, or even non-programmable), which helps tailor your heating and cooling to your routine and can improve energy savings.

Smart features stand out here, with compatibility for Apple HomeKit and Amazon Alexa, letting you control your thermostat through voice or a smart home app, which is handy if you already use those systems. The interface is modern and wall-mounted with a clock display and backlight, making it easy to read and use. Installation comes with a full kit including anchors and a mounting system, but since it’s hardwired, you might want to have a professional install it if you’re not comfortable working with electrical wiring.

On the downside, the display is manual rather than touchscreen, which some users might find less intuitive compared to newer models. Also, while the unit supports Wi-Fi control, it relies on batteries as backup power, which means occasional battery changes. This thermostat suits homeowners looking for solid heat pump compatibility combined with smart home integration and flexible scheduling without opting for the very latest touchscreen models.
