Set Thermostat to 68°F for Fall Comfort and Efficiency, Experts Advise

As the leaves begin to turn and a crispness fills the air, one of the most common questions among homeowners is: When should I turn on the heat, and what temperature should I set my thermostat to in the fall? The answer is a blend of comfort, health, and energy efficiency—a balance that’s especially important as energy costs and environmental concerns continue to rise.

The ‘Right’ Temperature: 68°F Is the Sweet Spot

According to HVAC professionals and energy experts, 68°F (20°C) is widely considered the optimal temperature for heating your home during the fall. This temperature offers a harmonious blend of comfort and energy efficiency. Specialists from Georgia Air state that maintaining your thermostat at 68°F creates a pleasant indoor environment that mirrors the mildness of fall, alleviates stress on your HVAC system, and keeps heating costs manageable[3][4].

Setting your thermostat just a few degrees lower than you might during the winter months can result in energy savings of up to 5% on your bill[3]. Not only will this help your wallet, but it also reduces your home’s environmental footprint.

What Do Health Experts Recommend?

It’s not just about comfort—health authorities also weigh in on the right temperature for home heating. The World Health Organization (WHO) recommends keeping indoor air temperatures between 64°F and 75°F (18°C to 24°C) for most people[2]. This range supports optimal health and well-being, particularly in the rooms where you spend the most time, such as your living room, bedroom, and kitchen.

If you’re caring for someone over the age of 65, have a child under two, or are managing chronic health conditions or allergies, experts suggest keeping your home at the warmer end of this range—closer to 68°F or even slightly higher[2]. These groups are more vulnerable to cold and may benefit from a little extra warmth as the weather cools.

When Should You Turn on the Heat?

The best time to turn on your heat is when indoor temperatures dip below 64°F (18°C). Until then, you can likely manage with an extra sweater or blanket[2]. Monitoring your indoor temperature is key; as soon as your living spaces consistently fall below that threshold, it’s time to fire up the furnace. Turning on your heat too early wastes energy, while waiting too long can lead to discomfort and potential health issues.

Day vs. Night: Adjust for Comfort and Savings

While 68°F is the recommended daytime setting when you’re at home, there’s room for adjustment at night or when you’re away.

• Nighttime: Lowering your thermostat to 60–62°F (15–17°C) while you sleep is a great way to save energy. Cooler temperatures at night can also promote deeper, more restful sleep[1].
• Away from home: If your house will be empty for an extended period, set your thermostat to 55–60°F (13–16°C). This prevents your home from getting too cold (and avoids frozen pipes in colder regions) while minimizing unnecessary energy use[1].

Tips for Efficient and Comfortable Heating

• Make gradual adjustments: Instead of making drastic changes, lower your thermostat by 1–2 degrees each day as fall arrives. This helps your body and your heating system adjust smoothly to cooler weather[1].
• Use programmable or smart thermostats: Automating your temperature settings makes it easier to maintain the ideal temperature throughout the day and night, even when you’re not home[1].
• Take advantage of natural warmth: Open curtains during sunny fall days to let in natural heat, and close them at night to retain warmth.
• Add layers: Wearing cozy clothing or adding extra blankets can help you stay comfortable at slightly lower indoor temperatures, further reducing energy costs.

Special Considerations

• Elderly, infants, and those with health conditions: Keep the thermostat a bit higher to reduce health risks[2].
• Humidity control: Maintaining a moderate indoor temperature (like 68°F) also helps keep humidity in check, preventing mold and respiratory discomfort[3].

The Bottom Line

68°F is the recommended setting for turning on your heat this fall—warm enough for comfort and health, cool enough for energy savings. Pay attention to the specific needs of your household, and don’t hesitate to nudge the temperature up a degree or two for vulnerable family members.

By following these guidelines, you’ll usher in the fall season with a home that’s comfortable, healthy, and energy-smart. And remember: sometimes, the best way to stay warm is a combination of the right thermostat setting and a cozy sweater. Stay warm, and enjoy the beauty of fall!
