Your Toilet Should Last 50 Years…

1930's central vac… And other estimates of how long appliances and components of a house should last

Everything in your house will require replacement. Here is a guide to the life expectancy of many of the components of the typical U.S. house. Please keep in mind that these are general industry standards, and family size and location can dramatically affect the expected life of an item. For example, furnaces last much longer in San Diego than they do in Chicago, and a family of 6 will need a clothes washer replaced sooner than a family of 2.

Home Inspectors will report the age of certain items such as water heaters and furnaces, but they do not itemize each component. It is up to the buyer to realize the age of appliances, and budget accordingly for replacement. If you are buying a house built in 1980, and the appliances look original, you will likely be faced with replacing them soon.
