What matters
Check that a thermostat works with your HVAC system and wiring before buying; some models need a C-wire or adapter. Also consider which smart-home app you use, whether you want room sensors, and how much you want to spend.
Who this is for
These picks are for U.S. homeowners replacing a compatible low-voltage thermostat who want app control, scheduling, or smart-home features. If you have a high-voltage system or are unsure about your wiring, check compatibility or ask an HVAC professional first.
The picks, one by one
Best overall: Google Nest Learning Thermostat (4th gen)
It pairs an easy-to-use dial and polished Google Home app with automatic learning, making it the strongest all-around choice for people who want the thermostat to adapt to their routine. Reviewers named it their overall pick after extended home use. Bob Vila’s tester used it for six months in a Florida home with frequent air-conditioning use. The reviewer praised its guided installation, intuitive app, and ability to adjust schedules based on household habits. It does not require a C-wire, according to the review, though compatibility with your specific HVAC system should still be checked. Skip it if you want a lower-cost thermostat or don’t use Google Home.
Good to know: It costs substantially more than basic smart thermostats.

It offers a broad set of smart-home connections and useful scheduling for less than the Nest, making it a good fit if you want more than basic app control without paying for a premium model. Bob Vila rated it highly for value, ease of setup, and functionality. The reviewer reported a roughly 15-minute installation and praised the app’s scheduling and energy insights. It supports Alexa, Google Assistant, and Apple HomeKit, and can work with room sensors; check the listing to confirm what is included. Skip it if you don’t want to deal with C-wire requirements or an adapter.

At around $60, it is a genuinely inexpensive smart thermostat that reviewers still recommend, with Alexa, Google, Apple Home, and Matter compatibility. Reviewed named it a value pick and described it as an entry-level option with useful app-based features. TechRadar’s January 2026 review also listed it at Amazon for about $60. It has a straightforward digital display rather than a more elaborate touchscreen, and the Resideo app provides its connected controls. Skip it if room-by-room sensing is important to you; reviewers note it does not support occupancy sensors.
Good to know: It requires a C-wire and lacks support for room sensors.
