Quick Reference: Ideal Indoor Temperatures
What Is a Normal Indoor Temperature?
Determining a normal indoor temperature involves several factors. Commonly, the temperature comfort zone is between 68°F to 72°F (20°C to 22°C). This range offers a pleasant balance for most activities and seasons, making it the ideal indoor temperature range for most households.
Here on Long Island, where we experience humid summers and cold winters, finding the right balance is especially important for both comfort and energy efficiency.
Seasonal Indoor Temperature Ranges: Winter vs. Summer
Indoor temperature needs change with the seasons. In winter, warmth is essential, while in summer, cooling becomes a priority. Each season requires different temperature settings to balance comfort and energy use.
Winter Settings
- Daytime: 68°F (20°C) when home
- Nighttime: 60-65°F for better sleep
- Away: 55-60°F to save energy
Lower your thermostat 7-10°F for 8 hours a day to save up to 10% annually on heating costs.
Summer Settings
- Daytime: 78°F (25°C) when home
- Nighttime: 72-75°F for sleeping
- Away: 85°F or off when gone
Each degree above 72°F can save 3% on cooling costs during Nassau County's humid summers.
