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.
