- There’s no better time to examine seals on doors and windows to check for air leaks. Caulk and weatherstrip as needed to seal in warm air and energy savings. Similarly, examine electrical outlets for air leaks, and where necessary, install foam gaskets behind them to prevent drafts.
- During the day, open curtains or drapes on south-facing windows to let sunlight heat your home naturally. Close window treatments at night for an added layer of window insulation.
- At the change in seasons, schedule a service appointment for your heating system to ensure that it can operate at an optimal level.
- Low-cost or no-cost steps for energy savings include taping or affixing heavy, clear plastic to the insides of your windowpanes to create an additional barrier against cold air. Ensure that the plastic is sealed tightly to the pane to help reduce infiltration.
- Use a programmable thermostat to set the temperature as low as is comfortable when you are home (ideally around 68 degrees). When you are asleep or away, turn the temperature down even lower. A downward adjustment of 10–15 degrees over long periods can save about 10% a year on heating and cooling costs, according to the Department of Energy.
