Winter energy use depends on your climate, heating system, and home. Before buying a new device, focus on the places where heat escapes and on settings you can manage consistently. These steps can improve comfort while giving you a clearer picture of what a larger upgrade might accomplish.
Find drafts and air leaks
Check doors, windows, and accessible attic or basement areas for unwanted air movement. Weatherstripping can help around moving parts such as doors, while appropriate caulk can seal some stationary gaps. Do not seal openings required for ventilation or combustion equipment. If you see moisture damage, identify its cause before covering the area.
Attic air sealing and insulation may be a better investment than a collection of small gadgets, but the right work depends on what is already installed. ENERGY STAR recommends sealing attic-floor leaks before adding insulation and keeping ventilation paths open. A home energy assessment can help prioritize the work.
Use thermostat settings that fit your schedule
If your heating system supports it, a programmable or compatible smart thermostat can reduce unnecessary heating while you are away or asleep. Start with a schedule that remains comfortable and follow the equipment manufacturer’s guidance, particularly for heat pumps or other systems with special controls. A connected thermostat is useful only when it works with your system and you use its settings.
Manage windows and daylight
In a sunny location, opening suitable blinds during the day may let sunlight help warm a room; closing coverings at night can reduce the chill felt near windows. If a window is drafty, inspect its seals. A curtain can improve comfort, but it does not replace the need to address a significant air leak or an unsuitable window installation.
Maintain the heating system
Check filters and maintenance intervals for your specific furnace or heat pump. Blocked supply or return vents and neglected maintenance can reduce comfort and efficiency. If some rooms are consistently cold, an HVAC professional can assess equipment, ductwork, and airflow rather than guessing at a product fix.
Buy only for a defined problem
- A draft at a door: compare weatherstripping that fits its gap and operating movement.
- A scheduling problem: check thermostat compatibility before considering a programmable or smart model.
- Low attic insulation: assess air sealing, moisture, ventilation, and the recommended R-value for your climate.
- Cold windows: inspect seals and consider appropriate coverings or a professional window assessment.
Track your own energy use over comparable weather periods if you want to assess results. Bills change with temperature, rates, occupancy, and heating fuel, so no single savings percentage is guaranteed by these tips.
