The Life Expectancy of Your Home Tech

The Life Expectancy of Your Home Tech

If our grumbling dishwasher is any indication, kitchen appliances—like any of your at-home tech—aren't built to last forever. But exactly how long do they last? You'll have to ask the National Association of Home Builders, who've been collecting data on the life of common home components. Read on for the real-life figures, in years, for the life of everything from security systems and air conditioners to gas ranges and refrigerators.

Teamed up with Bank of America, the National Association of Home Builders released the Study of Life Expectancy of Home Components. The data is from a few years back (2007 to be exact), but the study offers much more than just an educated guess at home tech life spans.

These figures might come in handy when you're deciding whether to repair or replace an appliance or home system. If your tech is near the end of its projected useful life, it might be best to go brand-new.
