10 Best Multi Stage Thermostat 2025 in the United States

The Google Nest Learning Thermostat (4th Gen, 2024) is a smart thermostat designed to help you save energy while keeping your home comfortable. It works with most heating and cooling systems, including gas, electric, heat pumps, and more, without usually needing a C wire, which makes installation simpler for many homes. You can control it easily from your phone or with voice commands through Alexa, Siri, or Google Assistant, adding great convenience if you already use smart home devices.

The large, bright display is easy to read from across the room and adjusts its brightness automatically or manually, which helps you check the temperature and settings without hassle. It also learns your habits and the way outdoor weather affects your indoor temperature to optimize heating and cooling, potentially reducing your energy bills by around 12% for heating and 15% for cooling. The included Nest Temperature Sensor allows you to manage temperature in different rooms, addressing hot or cold spots in your home. Notifications and suggested schedule changes appear in the Google Home app, letting you approve adjustments that may save more energy.

Installation is generally straightforward, and the thermostat works smoothly with popular smart home platforms thanks to Matter compatibility. While it covers a wide range of systems, some older or less common setups might not be fully supported, so checking compatibility first is important. Additionally, it relies on Wi-Fi and app connectivity, which may be a drawback if your internet is unreliable. The price is higher than basic thermostats, reflecting its advanced features but possibly making it less appealing for very budget-conscious buyers. This thermostat represents an excellent choice for those seeking an easy, smart, and energy-efficient way to control multi-stage heating and cooling, especially if app control and integration with popular smart home assistants are important.

The ecobee New Smart Thermostat Premium is a strong choice for anyone looking to upgrade their home heating and cooling system. One of its standout features is its energy-saving capability, which can help reduce heating and cooling costs by up to 26% annually, making it a financially savvy option. The included SmartSensor effectively manages temperature across different rooms, ensuring comfort without hot or cold spots, which is particularly beneficial for larger homes or areas with varying temperatures.

The built-in air quality monitor is another significant advantage, alerting users about poor air quality and providing suggestions for improvement. Coupled with its sleek design and vibrant display, the user interface is generally intuitive, making it easier for you to monitor your home's conditions.

In terms of smart features, it integrates well with major voice assistants like Siri, Alexa, and Google Assistant, allowing for effortless control of your home environment through voice commands. Additionally, the thermostat can alert users to potential security issues, such as open windows or doors, adding an element of safety to its functionalities. There are some drawbacks to consider. The advanced features require a subscription to the ecobee Smart Security plan for full functionality, which may not appeal to everyone. Installation is relatively straightforward, especially with the included Power Extender Kit for homes without a C-Wire, but some users might still find it a bit challenging without prior experience. It offers impressive compatibility with various HVAC systems, but it may not work with certain older models, so checking compatibility beforehand is essential. If you prioritize energy savings, smart home integration, and air quality monitoring, this thermostat is a solid option, but be sure to weigh the subscription costs and installation requirements against your needs.
