Household Appliance Life Expectancy
Refrigerators
Life Expectancy: 14 years for side-by-sides and top mounts, while bottom mount refrigerators are listed at around 17 years. Expect single-door refrigerators to last longer: around 19 years.
Those compact, dorm-style refrigerators are really just good for the life of your college career, since they average around 5 years.
Washing Machines
Life Expectancy: 11-14 years.
Top loaders tend to last longer than the front-loading machines.
Dryers
Life Expectancy: 13 years.
Good maintenance, such as keeping the vent clear and cleaning lint after every load, makes a big difference.
Dishwashers
Life Expectancy: 11-13 years.
The built-in versions tend to last longer than the portable models. If you wash a lot of dishes daily, your machine probably won't last as long as the one owned by your neighbor who never cooks.
Microwaves
Life Expectancy: 9 years.
New technology has meant big improvements over older models.
Window Air Conditioners
Life Expectancy: 12 years.
It's important to keep these appliances clean and regularly clean the filter in order to get maximum use. In terms of whole house units, the lifespan varies widely according to manufacturers, so there is no typical estimate.
In-Sink Disposers
Life Expectancy: 12 years.
Follow manufacturer guidelines carefully to keep this piece of equipment in top shape.
Gas or Electric Water Heaters
Life Expectancy: 6 years, plus.
There are more expensive water heaters with longer warranties, so if you're interested in an extra-long lifespan, do your homework.
Stoves
Life Expectancy: The AHAM makes distinctions between built-in ovens (16 years); drop-in single ovens (11 years); and slide-in single and double oven ranges (17-18 years).
"You finally get to a point over time with wiring and insulation where it should be replaced for safety," says Michael Ward, purchasing manager for A-1 Appliance in Nashville.
Cooktops
Life Expectancy: Single built-ins average around 13 years, while double built-ins are listed at a whopping 21 years.
