No matter what kind of heating system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. But remember: An energy-efficient furnace alone will not have as great an impact on your energy bills as using the whole-house approach. By combining proper equipment, maintenance and upgrades with recommended insulation, air sealing, and thermostat settings, you can save about 30 percent on your energy bill while reducing environmental emissions.
- Set your programmable thermostat as low as is comfortable in the winter and lower the setpoint when you’re sleeping or away from home.
- Clean or replace filters on furnaces once a month or as recommended.
- Clean warm-air registers, baseboard heaters, and radiators as needed. Make sure they’re not blocked by furniture, carpeting, or drapes.
- Eliminate trapped air from hot-water radiators once or twice a season. If unsure how to perform this task, contact a professional.
- Place heat-resistant radiator reflectors between exterior walls and the radiators.
- Turn off kitchen, bath and other exhaust fans within 20 minutes after you are done cooking or bathing. When replacing exhaust fans, consider installing high-efficiency, low-noise models.
- During winter, keep the draperies and shades on your south-facing windows open during the day to allow the sunlight to enter your home. Close them at night to reduce the chill you may feel from cold windows.
Select energy-efficient products when you buy new heating equipment. Your contractor should be able to give you energy fact sheets for different types, models, and designs to help you compare energy use. See the efficiency standards for information on minimum ratings, and look for the ENERGY STAR when purchasing new products.
