DID YOU KNOW?
The first air conditioning units were designed and installed in 1902 for humidity control — not comfort. [2] Today, AC is a summertime staple — but how we use it affects both our wallets and the planet.
STAY INFORMED
- Heating and cooling account for about 50% of energy use in most U.S. homes, making temperature control one of the biggest drivers of utility bills. [1]
- You can save up to 10% a year on heating and cooling costs by adjusting your thermostat 7°–10°F for 8 hours a day. [1]
- The smaller the difference between indoor and outdoor temperatures, the lower your cooling bill. [1]
HELPFUL TIPS
1. Set It to 78°F When You’re Home
- 78°F is the recommended summer setting when you're indoors and need cooling. This balances comfort with energy efficiency.
2. Supplement with Ceiling Fans
- If 78°F feels too warm, use ceiling fans to circulate air. Fans don’t lower temperature, but they make you feel cooler. [1]
3. Don’t Forget to Turn Off Fans
- Fans cool people, not rooms. Turn them off when you leave to avoid wasting electricity. [1]
ENERGY SAVINGS REMINDER
Your thermostat is a powerful tool for saving energy and money. Set it wisely, combine it with fans, and enjoy a cooler summer that’s easier on the planet.
