How Much Can You Save?
According to the U.S. Department of Energy, homeowners can save 10% to 12% on heating and 15% on cooling annually just by using a programmable thermostat correctly.

Real-World Savings Example
Let’s say you’re using a basic programmable thermostat and leave your HVAC running most of the day while away at work.
By switching to a smart thermostat and setting:
- Away temps: 62°F in winter / 78°F in summer
- Home temps: 70°F in winter / 74°F in summer
- Sleep temps: 64°F in winter / 76°F in summer
You could reduce HVAC runtime by up to 25%, translating to $200 or more in annual savings—especially in states with extreme seasonal temperatures like Texas, Florida, or Minnesota.
Tips to Maximize Savings with Your Smart Thermostat
1. Set Optimal Temperature Thresholds
Don’t crank it up or down more than necessary. Every degree can affect your bill by up to 3%.
Recommended settings:
- Winter heating: 68–70°F when home
- Summer cooling: 74–78°F when home
- At night or away: Drop or raise by 6–8°F
2. Use Smart Scheduling Features
Whether it’s a 5-2 weekday/weekend schedule or full 7-day customization, map out your family’s routine and build a schedule that reflects when you actually need heating or cooling.
3. Enable Geofencing
When you’re away, your thermostat should be too. Geofencing takes care of that automatically.
4. Regularly Review Usage Reports
These reports offer personalized insights into how your settings impact energy use—and how to improve them.
5. Don’t Forget Maintenance
Replace filters, clean sensors, and check HVAC performance. A smart thermostat can’t fix an inefficient furnace!

Common Questions About Smart Thermostat Savings
Do smart thermostats work with all HVAC systems?
Most models support standard HVAC systems (gas, electric, oil, heat pump), but always check compatibility. Some require a C-wire for installation.
Can I install a smart thermostat myself?
Yes, many are DIY-friendly. If your setup lacks a C-wire, you might need a professional or an adapter kit.
What’s the difference between smart and programmable thermostats?
Programmable models require manual scheduling. Smart thermostats offer learning, remote access, automation, and app integration—resulting in greater long-term savings.
