The Best Temperature Settings To Save Money On Heating And Cooling
The Sweet Spot Between Comfort and Savings
Does adjusting your thermostat feel like a constant tug-of-war between staying comfortable and saving money? You’re not alone. With heating and cooling accounting for over 50% of the average household’s energy bill, it’s one of the biggest expenses for most homeowners (Energy.gov). Luckily, finding the best temperature settings can help you cut costs without sacrificing comfort.
But it’s not just about saving money—it’s about reducing energy waste and doing your part for the environment. Every small adjustment you make has a ripple effect on both your bills and your home’s carbon footprint.
In this guide, we’ll break down the science of thermostat savings, provide tips for every season, and show you how to use smart technology to make the process easier. Whether you’re heating your home in winter or cooling it in the summer, there’s a simple solution to keep your space cozy without breaking the bank.
1. Why Your Thermostat Settings Matter More Than You Think
You might not realize it, but those small thermostat tweaks you make can have a huge impact on your energy consumption. In fact, according to the U.S. Department of Energy, setting your thermostat back by just 7°F–10°F for eight hours a day can save you up to 10% annually on heating and cooling costs.
Think about that. If your energy bill is $2,000 a year, that’s $200 saved—just by adjusting your thermostat a few degrees when you’re not home or asleep.
How Every Degree Adds Up
Here’s why those tiny adjustments matter so much:
- Each degree you lower your thermostat in the winter (or raise it in the summer) reduces your energy bill by 1%–3%.
- Over time, this adds up to significant savings, especially during peak heating and cooling months.
- It’s an easy, low-effort way to save money without making any major changes to your lifestyle.
2. The Science Behind Energy Savings
Heating and cooling your home isn’t just about flipping a switch. There’s actual science behind how your HVAC system works, and understanding it can help you make smarter decisions.
Why the Temperature Difference Matters
The greater the temperature difference between the inside and outside of your home, the harder your HVAC system has to work to maintain a comfortable indoor climate. For example:
- In the winter, if it’s 20°F outside and you set your thermostat to 72°F, your furnace is working overtime to make up that 52-degree gap.
- In the summer, setting your thermostat to 68°F when it’s 95°F outside puts your air conditioner under constant strain.
The solution? Keep your indoor temperature closer to outdoor conditions—within reason—to reduce energy use.
3. Ideal Thermostat Settings for Every Season
Winter: Stay Warm Without Overheating Your Bills
When it’s cold outside, it’s tempting to crank up the heat, but that’s one of the fastest ways to send your energy bills skyrocketing. Instead:
- When You’re Home: Set your thermostat to 68°F. This is warm enough to stay comfortable while wearing a sweater or using a blanket.
- When You’re Away or Sleeping: Lower it to 60°F–65°F. You’ll save energy while still keeping your home warm enough to prevent pipes from freezing.
Summer: Stay Cool Without Overspending
When summer hits, cooling your home can feel like a full-time job. Here’s how to save:
- When You’re Home: Set your thermostat to 78°F. This strikes a balance between comfort and efficiency.
- When You’re Away: Increase the temperature to 80°F–85°F. Your home will stay cool enough to prevent humidity issues, but you won’t be wasting energy on an empty house.
4. Day vs. Night: Adjusting Your Thermostat for Maximum Savings
Your energy needs change depending on the time of day, and your thermostat settings should reflect that.
Daytime Strategies
During the day, focus on comfort while minimizing energy waste. If you’re home, stick to the seasonal guidelines mentioned above. But if you’re out for work or errands:
- Set your thermostat higher in summer and lower in winter.
- Use a programmable thermostat to automate these changes so you don’t forget.
Nighttime Strategies
At night, you can save even more by lowering the temperature a few degrees. Studies show that cooler temperatures improve sleep quality, so it’s a win-win.
5. Seasonal Hacks to Maximize Efficiency
Each season comes with its own challenges, but these tips can help you optimize your thermostat settings year-round:
Spring and Fall: Harness Natural Airflow
- Open your windows on mild days to let fresh air circulate without using your HVAC system.
- Turn off the A/C or heat completely when outdoor temperatures are comfortable.
Winter: Keep the Warmth Inside
- Use heavy curtains to insulate your windows and keep heat from escaping.
- Seal cracks around doors and windows to block drafts.
Summer: Reduce Cooling Demands
- Close blinds or shades during the hottest part of the day to block out sunlight.
- Use ceiling fans to circulate air, making it feel cooler without lowering the thermostat.
6. Why Smart Thermostats Are Worth the Investment
If you’re still manually adjusting your thermostat, it might be time for an upgrade. Smart thermostats like Nest, Ecobee, or Honeywell Home can revolutionize how you manage your home’s heating and cooling.
Key Benefits of Smart Thermostats
- Automation: They learn your schedule and preferences, adjusting the temperature automatically to save energy.
- Remote Control: Use your smartphone to make changes, even if you’re not home.
- Energy Insights: Get detailed reports on your energy use to identify areas where you can save even more.
Geofencing: A Smart Way to Save
Many smart thermostats use geofencing technology to detect when you’ve left the house, automatically adjusting the temperature to save energy. When you return, the thermostat resets to your preferred settings—no effort required.
7. Bonus Tips to Save More Without Sacrificing Comfort
Saving energy doesn’t have to mean sacrificing your comfort. Here are a few extra tricks to lower your energy bills:
- Dress for the Season: Wear cozy sweaters in winter and lightweight clothes in summer to reduce reliance on heating and cooling.
- Use Fans Wisely: In summer, ceiling fans can make a room feel 4°F cooler. In winter, reverse the fan direction to push warm air down.
- Seal Leaks: Weatherstrip doors and windows to prevent drafts and keep your home insulated.
- Don’t Blast the Thermostat: Setting your heat or A/C to extreme temperatures won’t make your home warm or cool faster—it just wastes energy.
8. Zone Heating and Cooling for Larger Homes
If you have a big house, consider installing a zoned HVAC system. This allows you to control temperatures in specific areas, so you’re not wasting energy heating or cooling unused rooms. For example, you can keep your living room warm during the day while reducing heat in bedrooms until nighttime.
Smarter Temperature Choices, Bigger Savings
Finding the perfect thermostat settings is one of the easiest ways to save money and energy without sacrificing comfort. By following these guidelines, investing in smart technology, and making small adjustments, you can lower your energy bills and reduce your home’s environmental impact.
