Thermostat Settings During Extreme HeatWhen the temperature soars above 100°F, maintaining a comfortable and energy-efficient home environment becomes a challenge. Fayetteville Heating and Air is here to help you find the ideal thermostat settings to keep cool without breaking the bank.

Why Thermostat Settings Matter

Your thermostat plays a crucial role in regulating indoor temperatures, ensuring comfort, and optimizing energy use. During extreme heat, an efficient thermostat setting can prevent your HVAC system from overworking, reducing wear and tear and lowering utility bills.

Recommended Thermostat Settings

Daytime Settings: Set your thermostat to around 78°F when you are at home and need cooling. This temperature strikes a balance between comfort and energy efficiency. If 78°F feels too warm, consider using fans to circulate air and create a wind-chill effect, making the room feel cooler.

Nighttime Settings: At night, you can raise the temperature slightly, to around 82°F, as your body temperature naturally drops while you sleep. Use breathable bedding and wear light pajamas to stay comfortable.

Away From Home: When you are not at home, set your thermostat to around 85°F. This prevents your HVAC system from running unnecessarily while ensuring that your home doesn’t become excessively hot.

Additional Tips for Staying Cool

  1. Use Ceiling Fans: Ceiling fans can make a room feel up to 4°F cooler, allowing you to set the thermostat higher without sacrificing comfort.

  2. Close Blinds and Curtains: Blocking direct sunlight can significantly reduce indoor temperatures. Consider using blackout curtains for maximum effect.

  3. Seal Leaks: Ensure your home is properly sealed to prevent cool air from escaping and hot air from entering. Check windows, doors, and insulation.

  4. Schedule Regular Maintenance: Regular maintenance of your HVAC system ensures it operates efficiently. Replace filters monthly and schedule annual check-ups with Fayetteville Heating and Air to keep your system in top shape.

  5. Consider a Programmable Thermostat: A programmable thermostat can automatically adjust the temperature based on your schedule, optimizing energy use and comfort.

Benefits of Optimal Thermostat Settings

  • Energy Savings: Setting your thermostat to 78°F can save you up to 10% on cooling costs compared to lower settings.
  • Enhanced Comfort: Balanced temperatures prevent your home from becoming too cold or too hot, ensuring consistent comfort.
  • Prolonged HVAC Lifespan: Efficient thermostat settings reduce the strain on your HVAC system, extending its lifespan and reducing the likelihood of breakdowns.


By setting your thermostat to recommended levels and following these additional tips, you can stay comfortable even when temperatures soar above 100°F.
