It’s no secret that winterizing your home can slash your heating costs and reduce global warming pollution. But with today’s shaky economy, many homeowners might be wary of home improvements unless they can save money immediately—especially when home heating already accounts for nearly half of the average family's winter energy costs. While there are many ways in which you can reduce your home’s energy use, these five projects can deliver the quickest payback on your purchase:
- Insulate your attic. It is relatively easy, yet very cost-effective, to add insulation to your attic. The Department of Energy (DOE) suggests a minimum attic insulation level of R-38 (R-value is a measure of resistance to heat flow), equivalent to 12 to 15 inches of insulation. The DOE provides a map on its website (see the Related Resources) that lists recommended insulation levels for U.S. climates.
- Seal air leaks. Weather stripping, door sweeps, window shrink wrap, and other materials can be purchased at your local hardware store for $50 or less, and can save you as much as 10 percent in energy costs. If you have an old fireplace, consider installing glass doors (which can cost a couple hundred dollars or more) to help prevent heat from escaping out the chimney when not in use.
- Seal heating ducts. Leaky ducts from forced-air or heat pump systems can allow up to 20 percent of the warm air to escape. While most ductwork is hidden in walls and floors, you can seal duct leaks on your own in attics, basements, or garages, and in areas where ducts meet floor or wall vents. The DOE estimates that sealing leaky ducts can save you up to $140 annually.
- Install a programmable thermostat. An Energy Star-qualified programmable thermostat can cost as little as $30 but save you $100 or more each year on heating costs by automatically turning the heat down when you are asleep or away (so you don’t have to remember to do it yourself).
- Upgrade your furnace. If your heating system is more than 10 years old, consider replacing it with an Energy Star-rated model to cut your energy costs by up to 30 percent. Before you buy, make your home as efficient as possible first (following the tips above) so you can purchase the smallest system to fit your heating needs.
Homeowners can save even more money on energy efficiency improvements through tax breaks and other incentives offered by your utility or state government. And as part of the federal government’s recent economic bailout legislation, certain home improvements made in 2009 will be eligible for a tax credit (see the Related Resources).
