How old is too old?
If you’re considering when to replace appliances, use the average life span as a good reference point. The average lifespan of common major household appliances is:

• Washer: 10 years
• Dryer: 13 years
• Compactor: 6 years
• Dishwasher: 9 years
• Disposal: 12 years
• Microwave: 9 years
• Electric range: 13 years
• Gas range: 15 years
• Range hood: 14 years
• Exhaust fan: 10
• Refrigerator: 13 years
• Freezer: 11 years

Do you need a more energy-efficient appliance?
Energy costs are another important factor when deciding to replace appliances. If your old appliance has a lower energy-efficiency rating than new models, you might save more money in the long run by switching it out. That bright yellow and black EnergyGuide label attached to all appliances on the sales floor is a useful tool for estimating how much an appliance will cost to operate. An Energy Star label certifies that the appliance has met an international standard of superior energy efficiency created by the U.S. Department of Energy and the U.S. Environmental Protection Agency. Energy Star-approved clothes washers and refrigerators, for example, use about 20 percent less energy than standard models, according to the Department of Energy.
