How Long Do Appliances Really Last? The Honest Lifespan Chart

Manufacturers quote optimistic numbers; repair techs see the truth. Here are the real-world lifespans homeowners should plan around — with the tell-tale sign each machine gives before the end.

The chart

• Refrigerator: 10–15 years. Warning sign: running constantly, or the back feels hot while food struggles to stay cold.
• Dishwasher: 8–12 years. Warning: dishes come out gritty, standing water at the bottom, door gasket leaks.
• Washing machine: 8–12 years. Warning: banging spin cycles, and any moisture around the base — hose failures cause floods, not just repairs.
• Dryer: 10–13 years. Warning: clothes need two cycles. (Also clean the vent duct — lint chokes dryers to death and starts fires.)
• Oven/range: 13–15 years. The longest-lived kitchen appliance. Warning: uneven baking, error codes, igniters clicking forever.
• Built-in microwave: 8–10 years. Warning: weakening heat, sparking, dead spots on the keypad.
• Water heater (tank): 8–12 years. Warning: rusty hot water, rumbling sediment, moisture at the base. See our full water heater guide.
• Central AC: 10–15 years (less in extreme climates). Warning: rising bills, weak airflow, refrigerant top-ups every season.
• Furnace: 15–20 years. Warning: yellow burner flames, short-cycling, cold-air complaints every fall.
• Garbage disposal: 8–12 years. Warning: chronic jams, persistent leaks from the body (not the connections).

How to read this chart like a pro

Add up the ages in YOUR house. A 9-year-old home isn't facing one replacement — it's facing a refrigerator, dishwasher, washer, AND water heater all entering their failure windows together, because they were all installed the same month. That clustering is exactly why surprise-repair years hurt so much.

You can't stop the clock on any of these. You can decide, before the first one quits, whether each failure is a crisis or a flat service fee.
