Average Life Span of Homes, Appliances, and Mechanicals

Average Life Span of Homes, Appliances, and Mechanicals
The following chart details the predicted life expectancy of household materials and components. 
Interior and exterior paints can last for 15 years or longer, however homeowners often paint more frequently. Surface preparation is likely the most important determiner of paint life expectancy.

Appliance life expectancy depends to a great extent on the use it receives. Furthermore, consumers often replace appliances long before they become worn out due to changes in styling, technology and consumer preferences. Of a home’s major appliances, gas ranges have the longest life expectancy.

Note: Life expectancy varies with usage, weather, installation, maintenance and
quality of materials. Items listed as lasting 100+ years, especially those that open and close, often
fail prematurely due to misuse or overuse. This list should be used only as a general guideline, not
as a guarantee or warranty regarding the performance or life expectancy of any product.
