These devices can learn your schedule and heating preferences, automatically adjusting to keep you comfortable while saving energy.

When shopping for a smart thermostat, consider compatibility with your HVAC system. Some models work only with certain systems. Also, think about ease of use and whether you want features like learning capabilities, voice control, or integration with other smart home devices.
