Close the damper

If you own a fireplace, close the damper when there isn't a fire. An open fireplace damper pulls warm air out of your house, so be sure to close it once ashes have gone cold.

Replace filters

Clean or replace your heating system filters every few months to improve indoor air quality and energy efficiency. Consult the manual for the manufacturer's recommended maintenance schedule.

Don't block the heat

Dust or vacuum radiators, baseboard heaters, and furnace duct openings, and be sure not to block them with furniture, carpets, or drapes.

Get a pre-winter tune up

An annual pre-winter tune-up helps your water heater, furnace or boiler run more efficiently and last longer.

Get a home energy assessment

A professional home energy assessment is the best way to pinpoint where your home needs air sealing and insulation, and how much it requires.

Air-seal your home

Stop drafts with weather-stripping and caulking. Seal gaps and cracks with caulking, weather-strip windows and doors, and fill any large gaps in basement crawl spaces, dryer vents, windows, and foundations. Watch our How to air-seal video to learn more.

Install storm windows & doors

  • Storm windows will make your home more energy-efficient
  • Creates air space that decreases heat loss
  • Keeps outside air from seeping in and protect your windows and doors from storm damage
  • Acts as an air barrier to decrease infiltration if your primary window is leaky

See the "How to choose and install storm windows" guide for more detailed information.
