A programmable thermostat can save 10-15% on heating and cooling, but only if used correctly. Here's how to maximize savings.
Optimal Temperature Settings
Cooling Season - Home/Awake: 78°F - Away: 85°F (or off) - Sleep: 78-80°F
Heating Season - Home/Awake: 68°F - Away: 60-62°F - Sleep: 60-65°F
Setting Up Your Schedule
Typical Weekday | Time | Setting | Temp | |------|---------|------| | 6:00 AM | Wake | 68°F | | 8:00 AM | Leave | 60°F | | 5:00 PM | Return | 68°F | | 10:00 PM | Sleep | 62°F |
Weekend - Adjust if schedule differs - Consider separate weekend programs
Common Mistakes to Avoid
Mistake 1: Cranking Temperature Setting to 85°F doesn't heat faster than 68°F. Your system works at the same rate regardless.
Mistake 2: Constant Override Using "hold" defeats the purpose. Update your schedule instead.
Mistake 3: Too Aggressive Setbacks 10°F setback is effective. 20°F may save less due to recovery time.
Mistake 4: Wrong Fan Setting Keep fan on "auto" not "on" for most efficiency.
Advanced Tips
Use Recovery Time Good thermostats learn how long your home takes to reach temperature and start early.
Consider Occupancy - Working from home? Adjust schedule - Guest staying? Use temporary hold
Seasonal Adjustment Update programs as weather and schedules change.
Bay Area-Specific Tips
Our Mild Climate - Don't need extreme setbacks - Natural ventilation works many days - Fewer heating/cooling hours means schedule matters less
Temperature Swings - Coastal areas may need minimal programming - Inland valleys benefit more from setbacks
Time-of-Use Rates If you're on TOU rates: - Pre-cool before peak rates (4-9 PM) - Shift heating to off-peak hours - Smart thermostats can automate this
Troubleshooting
Schedule Not Running - Check "hold" isn't active - Verify time and date are correct - Replace batteries if needed
Uncomfortable Temperatures - Allow time for adjustment - Verify temperature reading is accurate - Check thermostat location
Upgrade Considerations
Smart vs. Programmable - Smart: Learns, remote access, more features - Programmable: Simpler, reliable, cheaper
Both save money if used properly. The best thermostat is one you'll actually program and use correctly.
