Most major home appliances last 10 to 15 years. A dishwasher is the short-lived one at 9 to 12 years, a refrigerator runs 10 to 15, and a gas range can push past 20. Those are national averages, though, and San Diego’s hard water and coastal air pull the real numbers down a bit. Here’s how long each appliance actually lasts, what shortens its life here, and how to know when yours is near the end.
How long do most appliances last?
Here’s the quick reference. These are the typical service-life ranges for a well-maintained home appliance, before major sealed-system or motor failures start showing up.
| Appliance | Typical lifespan |
|---|---|
| Refrigerator | 10–15 years (20+ for built-in) |
| Washing machine | 10–13 years |
| Clothes dryer | 10–14 years |
| Dishwasher | 9–12 years |
| Electric oven or range | 13–15 years |
| Gas oven or range | 15–20 years |
| Microwave | 9–10 years |
| Garbage disposal | 8–12 years |
| Wine cooler | 10–15 years |
Two things move a specific unit within its range: how hard it’s used, and how well it’s maintained. A family of five runs a washer twice as hard as a couple does. And an appliance on San Diego’s hard water ages faster than the same model in a soft-water region.
How long does a refrigerator last?
A refrigerator lasts 10 to 15 years on average, and built-in or high-end units like Sub-Zero, Thermador, and Viking routinely run 20 years or more. The compressor and sealed system are what set the ceiling. Once those fail on an older unit, replacement usually wins.
What tends to fail first is the cheap stuff: the ice maker, the water inlet valve, and the door gasket. Those are worth fixing at almost any age. In coastal San Diego homes, salt air corrodes the condenser coils, so a beachside fridge often shows its age closer to 10 years than 15. If yours is cooling poorly, our refrigerator repair page walks through what typical fixes cost.
How long does a washing machine last?
A washing machine lasts 10 to 13 years. Top-loaders tend to edge out front-loaders on raw longevity, but front-loaders use less water and are gentler on clothes. Either way, the drain pump, door gasket, drive belt, and suspension are normal wear parts, not signs the machine is done.
San Diego’s hard water is the quiet killer here. Mineral scale builds up in the valves and heating path and stiffens the pump. If your washer is over 10 years old and needs a new bearing or control board, replacement is usually the smarter call. Anything short of that is often a straightforward washing machine repair.
How long does a dryer last?
A clothes dryer lasts 10 to 14 years, and with clean venting it often reaches 18. Dryers have the simplest mechanics of any major appliance, so most failures are cheap parts: a heating element, thermal fuse, belt, or thermostat, each usually under $300 to fix.
The single biggest factor is airflow. A clogged vent makes the dryer run hotter and longer, which cooks the heating element and the electronics early, and it’s a real fire risk. Cleaning the vent line once a year is the highest-return thing you can do for a dryer’s lifespan. Our dryer vent safety guide covers the warning signs, and a worn-out element is a common dryer repair.
How long does a dishwasher last?
A dishwasher lasts 9 to 12 years, the shortest of the major kitchen appliances. It’s a wet, hot environment full of moving seals, and it runs on the same hard water everything else does. Scale buildup on the heating element and spray arms is what usually drags performance down first.
Before the machine is truly finished, you’ll see the fixable failures: a clogged drain, a leaking door seal, or a pump that won’t clear water. Those are worth repairing well into the unit’s life. If your dishwasher is over 10 years old and the control board or motor goes, replacement usually makes more sense. A drain or seal problem is a routine dishwasher repair.
How long does an oven or range last?
An electric oven or range lasts 13 to 15 years, and a gas model runs 15 to 20. Ovens have the longest useful lives of any major appliance because the parts that fail are simple and cheap: a bake element, an igniter, or a temperature sensor, all well under the cost of replacing the whole unit.
That means a range is almost always worth repairing. A gas igniter or an electric bake element is inexpensive, and the appliance around it has years of life left. If yours is heating unevenly or won’t hold temperature, that’s typically a quick oven and range repair, not a reason to replace.
What shortens appliance life in San Diego?
Two local conditions age appliances faster here than the national averages suggest.
Hard water. San Diego has some of the hardest tap water in the country. The mineral scale it leaves behind clogs valves, coats heating elements, and stiffens pumps in dishwashers, washing machines, and ice makers. That’s why a dishwasher here often lands at the low end of its range. A whole-home softener or regular descaling slows it down.
Coastal salt air. Homes near the water in La Jolla, Encinitas, Carlsbad, and Coronado see faster corrosion on exposed metal, especially refrigerator condenser coils and any outdoor or garage appliance. A coastal fridge can show sealed-system wear a few years earlier than an inland one.
How to make your appliances last longer
Most of what shortens an appliance’s life is preventable. A few habits add years:
- Clean the dryer vent yearly. Restricted airflow is the top cause of early dryer failure and a fire hazard.
- Descale the dishwasher and washer. Run a cleaning cycle every month or two to fight hard-water scale.
- Vacuum the refrigerator condenser coils twice a year. Dust-choked coils make the compressor work harder and die sooner.
- Don’t overload the washer or dryer. Overloading wears bearings, belts, and suspension early.
- Level every appliance. An unlevel washer or fridge vibrates itself apart over time.

When lifespan means repair vs. replace
Age alone doesn’t decide it. The honest test is whether the repair costs more than half of a comparable new unit, and whether the appliance is less than three-quarters of the way through its expected life. If both are true, replace. If not, repair almost always wins.
A first failure on a mid-life appliance is worth fixing. Three failures in 18 months means something systemic is wearing out, and that’s your replace signal. For the full math on every appliance, see our guide on repair or replace and our breakdown of appliance repair costs in San Diego.

Frequently asked questions
How long do appliances last on average?
Most major appliances last 10 to 15 years. Dishwashers are the shortest-lived at 9 to 12 years, refrigerators run 10 to 15, washers 10 to 13, dryers 10 to 14, and gas ovens can reach 20. Built-in and high-end units often last well beyond those ranges.
Which appliance has the shortest lifespan?
The dishwasher, at 9 to 12 years. It runs in a hot, wet environment with lots of seals and moving parts, and San Diego’s hard water speeds up scale buildup on the heating element and spray arms, which shortens its life further.
Which appliance lasts the longest?
Gas ovens and ranges last the longest, commonly 15 to 20 years. Their failures tend to be simple, cheap parts like igniters and bake elements, so they stay worth repairing for most of their life instead of being replaced.
Does San Diego’s hard water really shorten appliance life?
Yes. San Diego has very hard tap water, and the mineral scale it leaves clogs valves, coats heating elements, and stiffens pumps in dishwashers, washers, and ice makers. Descaling regularly or installing a water softener measurably extends the life of every water-using appliance.
How do I know if my appliance is near the end of its life?
Watch for a pattern, not a single fault. One repair on a mid-life appliance is normal. But when the unit is past its typical lifespan, needs a major part like a compressor or control board, and has failed more than once in a short window, it’s usually time to replace rather than repair.
