❄️ Winter Settings (December – February)

Goal: Stay warm + reduce heating costs

Recommended Thermostat Settings

  • When you’re awake & at home: 68°F (20°C)

  • When you’re asleep or away: 60–65°F (15–18°C)

πŸ’‘ Why? Every degree lower than 68°F for 8 hours can save you ~1% on your heating bill.

Bonus Tip

Use a programmable or smart thermostat to lower the temperature automatically at night and while you’re at work.


🌸 Spring Settings (March – May)

Goal: Ease into warmer weather without wasting energy

Recommended Approach

  • If daytime temps are mild (50–70°F), turn off your HVAC completely. Open windows instead! 🌬️

  • When heat or AC is needed:

    • Cooling: 72–75°F when home

    • Heating: 65°F if nights are still chilly

πŸ“Œ Pro tip: Spring is the perfect time to change your air filter and check for thermostat battery issues.

☀️ Summer Settings (June – August)

Goal: Stay cool without breaking the bank

Recommended Thermostat Settings

  • When you’re at home: 75–78°F (24–26°C)

  • When you’re away: 80–85°F (27–29°C)

❄️ Add ceiling fans – they make the room feel 4°F cooler, so you can raise the thermostat setting.

Smart Thermostat Bonus

A device like Nest or Ecobee can learn your schedule and adjust automatically.



πŸ‚ Fall Settings (September – November)

Goal: Prep for winter and enjoy free heating from the sun

Recommended Settings

  • Daytime: 68–70°F

  • Nighttime: 60–65°F (use extra blankets! πŸ›Œ)

🌞 Free heat hack: Open south-facing curtains during sunny fall afternoons, then close them at dusk.

Before winter hits:

✔️ Test your heating system
✔️ Seal window leaks
✔️ Replace thermostat batteries
