Set your thermostat to 68°F in winter and 78°F in summer, and use programmable settings to optimize energy savings throughout the day.
Proper thermostat settings can cut your energy costs by 10% annually while maintaining comfort. This guide reveals expert strategies for summer and winter, plus how to choose the right thermostat for your home.
Optimal Temperature Settings by Season
The U.S. Department of Energy recommends these baseline settings:
| Season | When Home | When Away/Sleeping |
|---|---|---|
| Winter | 68°F | 58-62°F |
| Summer | 78°F | 85°F |
Winter Heating Strategies
Every 1°F lowered for 8+ hours saves 1% on heating bills. Layer clothing and use supplemental heaters in frequently used rooms.
Summer Cooling Tips
Combine thermostat adjustments with ceiling fans (allowing 4°F higher settings), blackout curtains, and strategic tree shading.
Programmable vs Smart Thermostats
Programmable Thermostats
These allow 6+ daily temperature changes. Ideal for consistent schedules. Look for models with:
- Separate weekday/weekend programs
- Temporary override buttons
- Vacation hold features
Smart Thermostats
WiFi-connected models like Nest or Ecobee learn your patterns and adjust automatically. Key benefits:
- Geofencing turns systems off when you leave
- Energy usage reports
- Remote control via smartphone
Special Considerations
Heat Pump Systems
Standard setbacks can trigger inefficient backup heat. Use heat pump-specific thermostats with special algorithms.
Radiant Floor Heating
Due to slow response times, begin temperature changes 2-3 hours before needed.
Installation Tips
Proper placement prevents false readings:
- Interior walls only
- Away from direct sunlight
- Not behind furniture
- Avoid drafty areas
According to Energy.gov, improper placement can increase HVAC runtime by 15-20%.
Advanced Savings Strategies
Temperature Stacking
Gradually adjust settings seasonally to acclimate your household to more efficient temperatures.
Utility Programs
Many providers offer rebates for smart thermostat installation, with some Energy Star models qualifying for $100+ savings.
Whole-Home Approach
Combine thermostat adjustments with proper insulation and efficient heating systems for maximum savings.
