Every appliance in your house is on a countdown. It won't fail on schedule — some die young, some refuse to quit — but the averages are consistent enough to plan around. Knowing roughly where each machine sits in its expected life changes how you react to a repair quote: a $400 fix on a 4-year-old washer is routine, while the same quote on an 11-year-old washer is usually money thrown after a machine that's nearly done.
These ranges reflect what manufacturers, homebuilders' studies, and repair techs commonly report for typical residential use. Treat them as planning numbers, not expiration dates.
| Appliance | Typical Lifespan | What Usually Kills It |
|---|---|---|
| Refrigerator | 10–18 years (avg. ~13) | Compressor failure, sealed-system leaks |
| Freezer (standalone) | 12–20 years | Compressor wear; often outlives the fridge |
| Electric range / oven | 13–15 years | Control boards, heating elements |
| Gas range / oven | 15–19 years | Igniters, valves; few electronics to fail |
| Dishwasher | 9–13 years | Pump and motor wear, leaks, control boards |
| Microwave | 7–10 years | Magnetron failure — rarely worth repairing |
| Washing machine | 10–14 years | Bearings, drain pumps, suspension rods |
| Dryer | 10–13 years | Heating elements, belts, drum rollers |
| Garbage disposal | 8–12 years | Seal failure and leaks, motor burnout |
| Water heater (tank) | 8–12 years | Tank corrosion once the anode rod is spent |
| Water heater (tankless) | ~20 years | Heat exchanger scaling in hard water |
| Furnace | 15–20 years | Heat exchanger cracks, blower motors |
| Central air conditioner | 12–15 years | Compressor wear; shorter in very hot climates |
| Heat pump | 14–16 years | Runs year-round, so wear accumulates faster |
| Bathroom exhaust fan | ~10 years | Motor bearings; cheap units die sooner |
Two patterns stand out. Anything that heats water or moves it under pressure lives a harder life — dishwashers, disposals, and water heaters sit at the bottom of the chart. The dishwasher usually shows its age at the sink first: when loads start coming out gritty or filmed over, run the spray-arm and filter checks for a dishwasher not cleaning dishes before you write the machine off as worn out. And simpler machines outlast complicated ones: a gas range with knobs and an igniter has almost nothing on it that can cost $600 to replace, which is why it beats the dishwasher by half a decade.
A range like "10 to 14 years" for a washer isn't vagueness. It's three real variables stacking up:
This is also why two neighbors with identical refrigerators get different outcomes — and why a fridge that starts needing service calls every year is telling you something, even if each individual repair looks "cheap." If yours has reached that stage, start with the simple checks in our guide to a refrigerator that's not cold enough before paying for a diagnosis.
You can't plan around lifespans if you don't know ages — and nobody remembers when the dishwasher was installed. Spend twenty minutes once and you'll never guess again:
The rule of thumb most repair techs use: if a repair costs more than half the price of a comparable new appliance, and the machine is past half its expected life, replace it. A $550 control board on a 10-year-old dishwasher fails both tests — the new machine also gets you a warranty and lower energy use.
Run the math the other way, too. Cheap wear parts — a dryer belt, a washer drain pump, an oven igniter — cost little and routinely buy two or three more years, even on older machines. The 50 percent rule is about major components: compressors, motors, control boards, and anything involving a sealed system. And when the math says the washer is done, the replacement decision starts with format — our top-load vs. front-load washer comparison covers how the two types stack up on lifespan, repair costs, and water use.
This same math is what decides whether extended coverage makes sense. If you're weighing a warranty plan on a house full of mid-life appliances, our breakdown of whether a home warranty is worth it walks through what those plans actually pay for — and what they don't.
Running a washer that's visibly off-balance, load after load, destroys bearings years early — leveling it takes ten minutes. Ignoring a slow leak under a dishwasher rots the subfloor and the cabinet while the pump keeps dying of the water it's standing in. Skipping the water heater flush lets sediment cook the tank from inside; the full routine for stretching a tank is in our guide to how long a water heater lasts. A refrigerator leaking water inside is usually just a clogged defrost drain — a ten-minute clear-out — but ignore it and the water keeps pooling where food sits. And the most common mistake of all: paying for the third "small" repair in eighteen months on a machine already past its range. Add the invoices up. Together they were the down payment on the replacement.
Plan on roughly a decade from anything with a pump or a control board, fifteen-plus from furnaces and simple gas appliances, and treat water heaters as the one item to replace on your schedule rather than its own — a planned swap beats a flooded floor every time.
Furnaces and standalone freezers top the list at 15 to 20-plus years, and tankless water heaters reach about 20. All three share a trait: relatively simple jobs with no water being pumped, sprayed, or drained on every cycle.
Find the model and serial plate — usually inside the door, on the door frame, or on the back panel. Manufacturers encode the build date in the serial number, each with its own format; search the brand's site for its decoder. If you have the paperwork, the install date matters even more than the build date.
It depends on the repair. A drain pump or belt, yes — those are inexpensive wear parts. A main bearing job or control board on a machine at the top of its 10-to-14-year range, usually no: the repair approaches half the cost of a new washer that comes with a warranty.
Not reliably. Mid-range models from major brands tend to be the sweet spot — proven designs, available parts. Premium models add electronics, and electronics are what fail. The priciest fridge in the showroom and a basic one often share the same compressor.
Anything whose failure involves water: a tank water heater past ten years and any dishwasher or washer supply line showing rust or bulging. A planned replacement costs the same as an emergency one, minus the water damage, the weekend plumber rate, and the wet subfloor.
