Use a Programmable Thermostat to Save $180/Year

The Problem

Your HVAC runs at the same temp 24/7. You're heating/cooling an empty house.

The Hack

Set lower temps (heating) or higher (cooling) during sleep and work hours. Smart thermostats learn your schedule automatically.

Why It Works

Each degree of setback saves ~1% per 8-hour period. 7-10°F setback for 8 hours = 10% annual savings.

Pro Tips

• Programmable thermostat: $25-40
• Smart thermostat (Nest, Ecobee): $60-200 — learns your habits
• 68°F awake, 62°F sleeping = sweet spot in winter
• DOE estimates $180/year average savings
