Average annual savings on heating & cooling with smart thermostat habits
Why Heating & Cooling Is Your Biggest Bill
Heating and cooling accounts for about 43% of the average American's energy bill, according to the U.S. Energy Information Administration. For a household spending $1,800/year on electricity, that's $774 per year just on climate control.
The good news: this is also where small behavior changes produce the biggest dollar savings. Adjusting your thermostat by just 7–10°F for 8 hours per day saves up to 10% per year on heating and cooling, per the U.S. Department of Energy.
5 Free Thermostat Habits (Start Today)
These habits cost absolutely nothing and can be implemented in the next 10 minutes:
1. The 68/60 Winter Rule
Set your thermostat to 68°F when you're home and awake. Drop it to 60°F when sleeping or away. According to Energy.gov, this alone saves about $50–$80 per year.
2. The 78/85 Summer Rule
Set your AC to 78°F when home and 85°F (or off) when away. Each degree lower costs roughly 3% more to run your AC. Going from 72°F to 78°F saves about 18%.
3. Use Fans Instead of AC
A ceiling fan makes a room feel 4°F cooler and costs pennies per hour to run vs. dollars for AC. Use fans to raise your AC setpoint without sacrificing comfort.
4. Close Blinds on Hot Days
Sunlight through windows can raise a room's temperature by 10–20°F. Close south- and west-facing blinds on hot summer afternoons to reduce AC load significantly.
5. Service Your Filter Monthly
A clogged HVAC filter makes your system work up to 15% harder. Check it monthly and replace every 3 months (about $5–$10 per filter). This also extends the life of your HVAC system.
