10 Best Apple Thermostats 2025 in the United States

The Google Nest Learning Thermostat (4th Gen) is a smart thermostat designed to make managing your home’s temperature easy and energy-efficient. It stands out with broad compatibility, working with most 24V heating and cooling systems without needing a C wire in many homes, which simplifies installation. Many users will appreciate the attractive, polished obsidian design paired with a large, clear display that automatically adjusts brightness and shows useful info like the time or weather from across the room.

The thermostat learns your schedule and preferences over time, offering adaptive eco modes that save energy by adjusting temperatures based on outdoor weather and your habits. This can lead to noticeable savings—around 12% on heating and 15% on cooling bills. You can control the thermostat remotely via the Google Home app or with voice commands through Alexa or Google Assistant, adding convenience if you want to adjust settings away from home. The included Nest Temperature Sensor lets you target specific rooms, managing hot or cold spots more effectively.

Installation is generally straightforward, though some users might still need professional help depending on their HVAC setup. Full benefit from smart features relies on having a stable Wi-Fi connection and using the Google Home ecosystem, which may not suit users preferring other smart home platforms. While it doesn’t provide detailed energy reports like some competitors, it does notify you about energy-saving schedule changes, helping you stay informed. This thermostat is a solid choice for people looking to upgrade to a smart, energy-saving device that works well with voice assistants and offers easy remote control without complex setup.

The Google Nest Learning Thermostat (3rd Gen) is a well-designed smart thermostat that suits homeowners looking to automate and optimize their heating and cooling. It supports most heating and cooling systems (about 95%), making it broadly compatible, though it’s not Apple-branded itself—it works well with Alexa and Google Assistant, and can be controlled through apps on your phone, tablet, or computer. Installation is fairly straightforward and can typically be done in about 30 minutes with the included tools and instructions. The user interface is friendly and visually appealing, featuring a bright, high-resolution round display that shows temperature, time, or weather when you approach it.

Its standout smart feature is its ability to learn your schedule and temperature preferences over time, automatically adjusting for energy savings without much input from you. It also includes Home/Away Assist, which lowers energy use when no one is home, and HVAC monitoring to alert you about potential system issues. Energy reports are accessible via your phone, providing insight into how and when energy is used, with the Nest Leaf icon guiding you to energy-saving temperatures. Remote access is reliable, letting you control your thermostat from anywhere with an internet connection.

One minor drawback is that the Nest Temperature Sensor, which offers room-specific temperature control, is sold separately and adds to the cost. Also, while it works with many smart home systems, it doesn’t natively integrate with Apple HomeKit, which might be a consideration if you rely heavily on Apple’s smart home ecosystem. For those wanting a smart thermostat that learns habits, helps save energy, and offers easy remote control, the Nest Learning Thermostat is a solid choice with a sleek look and dependable features.

The ecobee Smart Thermostat Enhanced is a strong contender in the smart thermostat category, particularly for those looking to save on energy costs and embrace smart home technology. One of its most notable strengths is its energy efficiency, boasting the potential to save up to 26% annually on heating and cooling costs, thanks to its ability to adjust temperatures automatically when you're away. This feature not only enhances comfort but also contributes to savings on utility bills. Users will appreciate its compatibility with major voice assistants like Siri, Alexa, and Google Assistant, providing convenient voice control.

Installation is another area where the ecobee excels, as it comes with everything needed for a DIY setup, typically taking around 45 minutes. The Power Extender Kit included makes it accessible for homes without a C-wire, which is a significant plus for many users. The user interface is straightforward, making daily operation easy, even for those who aren't tech-savvy.

However, the ecobee Smart Thermostat Enhanced has some drawbacks. For instance, the SmartSensor, which enhances the thermostat's capabilities by measuring temperature and movement in other rooms, is sold separately, potentially increasing the cost for users wanting a comprehensive setup. Additionally, while it is wired and designed for longevity, some may still prefer the convenience of a completely wireless option, particularly in homes where installation might pose challenges. The thermostat’s reliance on Wi-Fi means that a stable internet connection is essential for its smart features to function optimally. If your Wi-Fi experiences outages or weaknesses, you might face limitations. Despite these minor inconveniences, the ecobee Smart Thermostat Enhanced is an excellent choice for energy-conscious consumers seeking a user-friendly and smartly designed device that integrates well with existing smart home setups.
