Energy Saving Tips

  • Keep blinds or drapes open on sun-exposed windows during the day — however in the summer, keep them closed to keep your interior cool.
  • Close fireplace dampers when not in use.
  • Plug leaks around windows and doors with caulking and weather-stripping.
  • Add insulation to walls, attics and basements.
  • Make sure air ducts are insulated and sealed.
  • Get a professional to tune up the furnace ahead of the heating season.
  • Invest in a programmable thermostat, which can be set to lower temperatures at night or when you're away.
  • Replace leaky, single pane windows, doors and skylights with products designed for cold climates.
  • Replace old furnaces and heat pumps with fuel-efficient models.
