Lifespan of Major Appliances

21 June 2010

recycle me!Just because old appliances continue to technically function does not mean that they are working for you.  While I am a big fan of waste-not, want-not, keeping an old household appliance past its due date means higher utility bills and lower performance.  My general rule of thumb is that if your appliance is old enough to vote, it’s time to say goodbye. Here’s a more technical list of the typical lifespan of major household appliances from Appliance Magazine.

Shortest lived appliances goes to compactors, dehumidifiers and humidifiers; longest lifespan are gas boilers, gas furnaces, oil furnaces and heat pumps.

    Interesting — I was always of the belief that appliances should be kept until they die on their own. I’m wondering: is the ‘expiration date’ due to the fact that an appliance’s efficiency degrades over time, or that more energy efficient models are available due to better technology? Either way, I’m finally convinced that it’s time to kick our old dishwasher to the curb and get a more efficient one. Thanks!
