Ideal Thermostat Settings for Different Seasons
Winter: Stay Warm Without Wasting Energy
During the colder months, the U.S. Department of Energy recommends setting your thermostat to 68°F (20°C) while you’re at home and awake. This temperature provides a comfortable indoor climate without excessive heating costs.
However, when you’re asleep or away for several hours, lowering the thermostat by 7-10°F (4-6°C) can reduce heating expenses by up to 10% annually. Consider setting it between 58-62°F (14-17°C) at night or when you’re out.
If you work long hours or travel often, investing in a programmable or smart thermostat can automate these adjustments for maximum savings.
To maximize energy efficiency during winter, try these additional strategies:
- Use heavy curtains or thermal drapes to insulate windows and keep the warmth inside.
- Seal air leaks around doors and windows to prevent heat loss.
- Dress warmly and use blankets to stay cozy without cranking up the heat.
- Reverse ceiling fans to push warm air downward and improve circulation.
Summer: Keep Cool Without Overworking Your AC
In the warmer months, the best temperature setting for energy efficiency is 78°F (26°C) when you’re at home. This helps maintain a comfortable yet cost-effective cooling environment.
When you’re away from home, raising the thermostat by 7-10°F can significantly cut down on cooling costs. The recommended range while away is 85-88°F (29-31°C).
For additional energy savings, consider the following:
- Use ceiling fans to circulate cool air, making it feel cooler than it actually is.
- Close blinds and curtains during the day to block out heat from the sun.
- Avoid using heat-generating appliances like ovens, dryers, and stoves during peak heat hours.
- Ensure your AC unit is well-maintained with regular filter changes and professional tune-ups.
Spring & Fall: Take Advantage of Mild Weather
The transitional seasons provide an opportunity to use less heating and cooling. During spring and fall, take advantage of natural ventilation:
- Open windows and doors to let in fresh air and create cross-breezes.
- Use ceiling fans instead of HVAC systems whenever possible.
- Adjust your thermostat to match outdoor temperatures for a more natural, energy-efficient home climate.
Pro Tips for Maximum Energy Efficiency
💡 Upgrade to a Smart Thermostat
A smart thermostat learns your habits and adjusts temperatures automatically to save energy while keeping your home comfortable. Many models also provide energy usage reports, helping you track savings over time. Smart thermostats allow remote control via smartphone apps, so you can adjust settings even when you’re away. Some popular models include Nest, Ecobee, and Honeywell Home.
💡 Use Zoned Heating and Cooling
If your home has multiple rooms, consider using zoned HVAC systems or space heaters to only heat or cool the areas you frequently use, rather than the entire house. Zoned systems can divide your home into different climate-controlled areas, significantly improving efficiency and comfort.
💡 Adjust Based on Humidity
Humidity plays a big role in how hot or cold a room feels. Using a dehumidifier in the summer can make higher thermostat settings feel more comfortable, reducing the need for excessive cooling. Conversely, adding a humidifier in the winter can make lower temperatures feel warmer.
💡 Regular HVAC Maintenance
Ensure your heating and cooling systems are running efficiently by cleaning or replacing air filters every 1-3 months and scheduling professional HVAC maintenance at least once a year. Dirty filters can force your system to work harder, increasing energy costs and reducing air quality.
💡 Leverage Natural Temperature Control
- In winter, open curtains during the day to let in natural sunlight and warmth, then close them at night to trap heat inside.
- In summer, keep blinds and curtains closed during the hottest parts of the day to block out heat and reduce the cooling load.
- Plant trees or install awnings around your home to provide natural shade and insulation.
How Much Can You Save?
According to the U.S. Department of Energy, adjusting your thermostat by just 7-10°F for at least 8 hours per day can help you save up to 10% per year on heating and cooling costs.
For example, if your annual heating and cooling bill is $1,500, you could save $150 or more simply by optimizing your thermostat settings. The savings can be even greater when combined with energy-efficient home improvements like better insulation, weather stripping, and energy-efficient windows.
The Environmental Protection Agency (EPA) reports that smart thermostat users can save an average of $180 per year, making these devices a worthwhile investment for long-term energy conservation.
Additional Cost-Saving Measures
- Weatherproof your home by sealing gaps in doors, windows, and ductwork.
- Upgrade to energy-efficient HVAC systems with high SEER (Seasonal Energy Efficiency Ratio) ratings.
- Use energy-efficient LED bulbs and appliances to further reduce electricity usage.
- Monitor your energy bills to identify trends and adjust settings accordingly.
Last words
By following these thermostat best practices, you can stay comfortable throughout the year while reducing your energy footprint and lowering your monthly bills. Small adjustments can lead to big savings in the long run. Whether it’s investing in a smart thermostat, using zoned heating and cooling, or making simple lifestyle changes, each step contributes to a more energy-efficient and cost-effective home.

Frequently Asked Questions (FAQ)
- What is the best thermostat setting for energy savings?
The best thermostat setting for energy savings depends on the season. The U.S. Department of Energy recommends setting your thermostat to 68°F (20°C) in winter when you’re home and 78°F (26°C) in summer for cooling efficiency. Adjusting temperatures while you’re away can lead to additional savings.
- How much money can I save by adjusting my thermostat?
Adjusting your thermostat by 7-10°F for at least 8 hours a day can save up to 10% per year on heating and cooling costs. If your annual energy bill is $1,500, you could save around $150 or more with these simple changes.
- Is it better to keep my thermostat at a constant temperature?
No, keeping your thermostat at a constant temperature all day wastes energy. Instead, use a programmable or smart thermostat to automatically adjust temperatures based on your daily routine. Lowering or raising the temperature while you’re asleep or away can significantly cut costs.
- Should I turn off my AC or heating when I leave the house?
Rather than turning off your HVAC system completely, it’s better to adjust the thermostat to a more energy-efficient setting. In winter, lower it by 7-10°F when away, and in summer, raise it by the same amount to prevent excessive energy use.
- Are smart thermostats worth the investment?
Yes, smart thermostats can optimize your home’s energy usage, learn your habits, and provide remote control via mobile apps. They can help save an average of $180 per year, making them a cost-effective solution for energy efficiency.
- What’s the ideal thermostat setting when sleeping?
For better sleep and energy savings, set your thermostat to 60-67°F (16-19°C) in winter and raise it slightly in summer while using a fan or light bedding for comfort.
- How can I make my home more energy-efficient without changing the thermostat?
You can improve energy efficiency by:
- Using ceiling fans to circulate air
- Sealing air leaks around windows and doors
- Installing thermal curtains for insulation
- Regularly maintaining your HVAC system
- Can I save energy by using a space heater instead of central heating?
Space heaters can be useful for heating small areas but may not be more efficient than a well-managed central heating system. They should be used sparingly and only in occupied rooms.
- Why does humidity affect thermostat settings?
High humidity makes a room feel hotter, so in summer, using a dehumidifier can make higher thermostat settings feel cooler. In winter, adding moisture with a humidifier helps rooms feel warmer at lower temperatures.
- What is the most efficient way to use my thermostat year-round?
- Winter: Set to 68°F (20°C) when home, lower to 58-62°F (14-17°C) when away
- Summer: Set to 78°F (26°C) when home, raise to 85°F (29°C) when away
- Spring/Fall: Take advantage of natural ventilation to minimize HVAC use
