Best Thermostat Setting for Lowering Your Energy Bill

Keeping your home comfortable while saving money on your energy bill is easier than you think. One of the simplest ways to do this is by adjusting your thermostat settings. Small changes can make a big difference in your energy costs without sacrificing comfort. In this article, we’ll share tips to lower your energy bill and guide you on the best thermostat settings for every season.

Why Thermostat Settings Matter

Heating and cooling your home accounts for a huge part of your energy bill about 51% on average in the U.S., according to the U.S. Energy Information Administration. That’s more than half of your energy costs! By managing your thermostat effectively, you can reduce energy use and save money.

Even adjusting your thermostat by just a few degrees can lead to significant savings. The U.S. Department of Energy reports that lowering or raising your thermostat by 7-10°F for 8 hours a day can reduce heating and cooling bills by up to 10%.

Best Thermostat Settings by Season

Spring and Fall

Spring and fall weather can be unpredictable. Sometimes you need heating, sometimes cooling. Here’s what experts recommend:

• Warm days: Set your thermostat to 78°F while at home. If you leave the house, increase it to 86°F.

• Cool days: Set it to 68°F when you’re home and awake. Lower it to 65°F while sleeping. If you’re away, drop it further to 60°F.

Most modern thermostats have an “Auto” mode, which allows you to set upper and lower temperature limits. Smart thermostats can even make these adjustments automatically.

Winter

During the winter, a comfortable temperature is 68°F when you’re home and awake. While sleeping or away, lowering it to 63-65°F can save more money. Dressing warmly indoors can make it easier to stay comfortable at lower temperatures.

If you have a heat pump, adjust the thermostat in small increments to avoid using less efficient backup heat strips. Heat pumps are most efficient when temperature changes are modest.

Summer

In the summer, a thermostat setting of 78°F is ideal while you’re home. If you leave for more than four hours, set it higher—up to 85-88°F. These adjustments can save up to 10% on cooling costs while keeping your home comfortable.

Sleeping

A good night’s sleep also benefits from the right temperature:

• Winter: 65°F
  
• Summer: 78°F
  
• Spring/Fall: 65°F when cool, 78°F when warm

This approach reduces HVAC usage and helps you sleep better.

Tips to Lower Energy Bill Beyond Thermostat Settings

• Use a Programmable Thermostat: Set it to automatically adjust temperatures while you’re away or asleep.

• Seal Windows and Doors: Prevent warm or cool air from escaping.

• Use Fans: Ceiling or portable fans can circulate air and allow higher thermostat settings in summer.

• Maintain HVAC Systems: Clean filters and schedule yearly maintenance to keep your system running efficiently.

• Block Direct Sunlight: Use shades or curtains to keep your home cooler in summer.

Smart thermostats often include energy-saving features like learning your habits and suggesting ideal settings for cost savings.

How to Find Your Ideal Thermostat Settings

Everyone’s comfort level is different. Start with the recommended settings and adjust a degree or two until you find your perfect temperature. Track your energy bills to see how changes affect your costs. Over time, small adjustments can add up to big savings.
