Tip 1 - Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer.
Tip 2 - Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
Tip 3 - Don't place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
Tip 4 - Clean or replace filters on furnaces once a month or as needed.
Tip 5 - Clean warm-air registers, baseboard heaters, and radiators as needed; make sure they're not blocked by furniture, carpeting, or drapes.
Tip 6 - During the heating season, keep the draperies and shades on your southfacing windows open during the day to allow the sunlight to enter your home and closed at night to reduce the chill you may feel from cold windows.
Tip 7 - During the cooling season, keep the window coverings closed during the day to prevent solar gain.
