Top 10 Tips

1. Keep your thermostat setting at 68° F degrees in the winter and 78° F degrees in the summer. Set the thermostat 5 to 10 degrees lower when sleeping or away.
2. Clean or replace heating and cooling system filters as needed and close vents in unused rooms (unless you have a heat pump). Check and maintain your heating and cooling system annually.
3. Consider storm doors and windows or double-paned glass to help keep indoor air inside and outdoor air outside.
4. Use caulking and weather-stripping to plug up cracks and air leaks around windows and doors.

5. Make sure you have adequate insulation in your attic, under floors, around basements, in crawl spaces, and around foundation walls.
6. Try a lower water heater thermostat setting such as 120° F and install a water heater jacket.
7. Install water-flow restrictors in showers and faucets.
8. Don't let hot water run while washing, shaving, or doing dishes
9. Don't use the dishwasher or sink for less than a full load. Use cold water instead of hot for washing clothes.
10. Don't block heating or cooling outlets, such as radiators or registers, with furniture, carpets, or draperies.

11. Use low-power light bulbs and lower wattages where possible. Turn off unneeded lights.
