The most effective ways to reduce heating costs are sealing air leaks, adding insulation, and maintaining your furnace. Small habit changes help too.
Caulk and weatherstrip windows and doors, seal gaps around pipes and wires, and add outlet gaskets on exterior walls. Close the fireplace damper when not in use, and consider glass doors or an insert.
The attic is usually the best place to start. Check depth and uniformity, and add insulation if it looks thin. Insulate water heater pipes and any ductwork in unheated areas.
Replace filters regularly, schedule an annual furnace service, and bleed radiators if you have them. Keep vents and returns clear.
Open south-facing curtains during the day to let in warmth, and close them at night. Use rugs on cold floors.
A programmable or smart thermostat can lower the temperature when you sleep or are away. Check your utility for rebates and free energy audits, which can point out the best improvements for your specific home.
