Program your thermostat efficiently
A programmable thermostat saves 10–15% on heating/cooling, if you set it right.
What you'll learn
- The Department of Energy setpoints for San Diego (78°F home / 85°F away)
- Why raising 7–10°F when you're gone 8+ hours saves the most
- Why "fan auto" beats "fan on" for efficiency
- Whether a smart thermostat pays back for your home
Step by step
- Set a weekday schedule: cooler at bedtime, higher during workday.
- Use "hold" or "vacation" mode when leaving for 3+ days.
- Keep the fan on "auto," not "on."
- Replace batteries annually on battery-powered models.
Safety note
Smart thermostats (Nest, ecobee) learn your schedule automatically. Most pay back in under 2 years in San Diego.
