Effectiveness depends on user input and consistent scheduling
According to Energy.gov, both types can lower your bill, but smart models take the guesswork out of energy-saving habits.
Comfort & Convenience
Smart thermostats enhance comfort by adjusting your AC automatically based on time of day, home occupancy, or even local weather. Features like geofencing and adaptive learning help maintain a comfortable environment without constant adjustments.
Programmable thermostats improve efficiency over manual models, but they lack real-time adjustment or learning features. If your schedule changes frequently, you’ll need to update settings manually.
