Invest in an energy-efficient furnace.
Invest in an energy-efficient furnace. Select an energy-efficient furnace model by looking for an AFUE (annual fuel utilization efficiency) rating of 90 percent or greater.
Maintain the furnace.
Maintain the furnace. Clean your furnace filters monthly or replace if necessary. A clean unit runs more efficiently
Use natural gas for heating.
Use natural gas for heating. Consider switching to a natural gas heating system. Natural gas is less expensive than other heating fuels.
Use insulation.
Insulate your attic to an R-value of 38 for a gas-heated home and 50 for an electrically heated home; your walls to an R-value of 19; and your sill box (upper portion of your basement walls) to an R-value of 10. Proper insulation allows you to use less energy to keep your home warm.
Change your thermostat settings.
Change your thermostat settings. In the winter, set your thermostat at 60° F when you are sleeping or gone. Set the thermostat to 68° F when you are at home. This can save 10 percent or more on your heating bills every winter.
Turn down the thermostat when away.
Turn down the thermostat when away. If you are going to be away for an extended period of time, turn your thermostat down to save energy but never lower than 40° F. If you have delicate houseplants, keep the setting at 50° F or higher.
Let the sun in.
Let the sun in. The sun’s energy can have a noticeable effect on the temperature in your home, especially from windows facing south and west. Keep window shades and drapes open during winter months to let in the sun’s radiant heat.
Use the fireplace sparingly.
Use the fireplace sparingly. Many older natural fireplaces are inefficient and draw more heat out of the house than they produce. Close the flue to eliminate drafts when not in use.
Control air flow.
Control air flow. If you are building a home, replacing heating equipment or remodeling, talk to your heating contractor about the options available to ensure proper air flow. Controlling air flow into and out of your home ensures energy efficiency, comfort and low energy costs.
