In the winter, you can keep costs low and save energy by keeping your thermostat at 68 degrees Fahrenheit while you are at home during the daytime. According to energy.gov, setting your thermostat lower by about 10 to 15 degrees for 8 hours per day can bring an energy usage reduction of 5 to 15% per year on your home energy bill.
Depending on your family’s personal comfort preferences, one idea you may consider is lowering the thermostat at night while you sleep. Many people find it comfortable to sleep in a cooler environment while using winter blankets to regulate warmth. It’s important to note that indoor humidity plays a role in the comfort of the air in your home.
During the warm weather, it’s recommended that you set your home’s cooling system to 78 degrees Fahrenheit while you’re home. If you plan to leave for four hours or more, consider adjusting your thermostat so the cooling system only comes on if the temperature tops 88 degrees Fahrenheit. By some estimates, every single degree higher you set your thermostat over 78 degrees Fahrenheit in the summer months, you could save approximately 6% to 8% off your home energy bill, per degree.
So, keeping your home’s temperature slightly higher and using the best settings for spring and summer can ultimately help save you money.
