How Long Do Appliances Actually Last? A Repair-vs-Replace Guide

"How long is this thing supposed to last?" is a question that only comes up at the worst possible time: a repair tech is standing in your kitchen with a quote, or the washer just started making a noise it's never made before, and you're trying to decide in about thirty seconds whether to pay for the fix or start shopping. Most answers online are useless in that moment, "it depends," "check the manual," "every appliance is different." Here are real ranges, and an actual framework for the decision.

Average lifespans, by appliance

These are typical ranges under normal use, not guarantees, a heavily-used appliance in a large household wears faster than the same model in a two-person home. But they're a real starting point, not a shrug:

• Refrigerator: 10-20 years
• Dishwasher: 9-12 years
• Washing machine: 10-13 years (front-load models tend to run shorter than top-load)
• Dryer: 10-13 years
• Water heater (tank): 8-12 years
• HVAC system / furnace: 15-20 years
• Garbage disposal: 8-12 years
• Microwave: 7-10 years

Age isn't the only variable, it's just the easiest one to know

Two identical dishwashers, one in a house with hard water and heavy daily use, one in a light-use vacation home, will not age the same, even though the calendar says they're both six years old. Water quality, usage intensity, install quality, and how well it's actually been maintained all move the real number meaningfully. Age is the variable everyone defaults to because it's the only one anyone actually knows. The others matter just as much, they're just harder to track, which is exactly why most people don't.

The actual repair-vs-replace math

The rule of thumb worth knowing: if a repair costs more than about 50% of a full replacement, replacement is usually the better bet, especially once the appliance is already past the midpoint of its typical lifespan. A $200 repair on a 3-year-old dishwasher is an easy yes. The same $200 repair on a 13-year-old dishwasher is a different conversation, you're not just paying to fix today's problem, you're likely buying a few more months before the next one.

Two things push the math further toward replacing, even when a repair looks tempting: older appliances are usually meaningfully less energy-efficient than current models, so part of the "savings" from repairing gets quietly eaten by a higher utility bill every month after. And for anything safety-adjacent, water heaters, gas furnaces, don't stretch a repair just to save money. That's the one category where "let's get one more year out of it" is the wrong instinct.

The real tell is maintenance history, not the calendar

An appliance that's had zero maintenance, no filter changes, no descaling, no coil cleaning, ages faster than its listed lifespan suggests, regardless of what the average says. This is exactly where knowing the actual install date, model, and service history changes the decision from a guess to a real answer: a well-maintained appliance at the high end of its typical range is a very different repair-or-replace call than a neglected one at the low end, even if they're the same age on paper.

Where this gets easier with the right tool

This is the specific gap between "the internet says 10-13 years" and "what should I actually do about my washer." Residely's AI Cues are tuned to your actual appliances, not a generic calendar, factoring in the real install date and service history instead of a guess, so the maintenance reminders that show up are relevant to your specific machine, not a category average. And when something does need attention, the Auto Manual Finder pulls the official manual for your exact model automatically, so you're troubleshooting against the real spec sheet instead of a generic guide that may not even match your unit.
