How Long Do Home Appliances Last? Lifespan Guide for Every Major Appliance
How long refrigerators, washers, dishwashers, HVAC and water heaters last, how climate and region change that, and when to repair or replace.
In this article
Quick answer: Most major appliances last roughly 9 to 20 years, and published figures differ by source and by climate. Replace one when a repair costs more than half the price of a new unit, and keep every appliance's model and serial number where you can find it.
Why appliance age matters
Knowing how old your appliances are, and how long they usually last, is the difference between planning a replacement and living through an emergency. A refrigerator that dies on a holiday weekend, a washer that floods the laundry room and an AC that fails in July are all stressful and expensive, and most of those failures are predictable.
The lifespans below are typical ranges, not guarantees. Even the sources disagree: InterNACHI's life expectancy chart, Consumer Reports, the National Association of Home Builders (NAHB) and manufacturers publish different numbers, so the chart shows the range across them. NAHB's own life-expectancy study notes that results depend on installation quality, maintenance, weather and climate, and intensity of use.
How to read the numbers
- Use the range to plan, not to decide. An appliance at the end of its range is not broken, but it has earned a spot on your replacement list.
- Age plus a repair bill is the real trigger. Consumer Reports' rule of thumb is that a repair costing more than half the price of a new appliance is probably not worth it. For a costly model, repairs stay worthwhile longer.
- Consider the whole system. For HVAC, manufacturers such as Bryant say age is a planning guideline, not a requirement to replace, so weigh repair history and efficiency too.
Kitchen appliances
Refrigerator: About 9 to 14 years in InterNACHI's and Consumer Reports' figures, with NAHB's study listing up to 17 for standard models. Warning signs include inconsistent temperatures, excessive condensation, a compressor that runs constantly and rising repair bills. Consumer Reports advises vacuuming the condenser coils about once a year.
Dishwasher: About 9 to 10 years. Warning signs include water that will not drain, dishes that come out dirty after you clean the filter, door latch problems and rust inside the tub. Consumer Reports suggests cleaning the filter every couple of months.
Oven or range: About 15 to 17 years for gas and 13 to 15 for electric (InterNACHI), with NAHB listing up to 19 for gas. Warning signs include uneven heating, burners that will not light and control board failures.
Microwave and garbage disposal: InterNACHI lists about 9 years for a microwave and about 12 for a disposal. Watch for arcing or a damaged door seal on a microwave, and leaks from the bottom or frequent resets on a disposal.
Laundry
Washer: About 8 to 12 years, and Consumer Reports puts the average close to 10. State Farm advises replacing washer hoses every three to five years, or sooner if they bulge, crack or leak, because a burst hose can flood a laundry room.
Dryer: About 10 to 14 years. The U.S. Fire Administration found failure to clean was the leading factor in clothes dryer fires from 2018 to 2020 (31%), so clear the lint screen and vent. Consumer Reports also recommends metal ducting over vinyl or foil.
HVAC and water systems
Central AC: About 12 to 20 years: Bryant lists 12 to 15 and Lennox 15 to 20. Warning signs include refrigerant leaks, frozen coils, or rising energy bills without a change in use. Change filters on schedule and have the system serviced each year. See our HVAC maintenance schedule.
Furnace or heat pump: Furnaces last about 15 to 25 years and heat pumps about 10 to 15, according to Bryant and InterNACHI. Warning signs include short cycling, uneven heating or carbon monoxide alarms going off.
Water heater: Tank models last about 8 to 12 years (HomeGuide) and up to 15 by the Department of Energy's estimate, and tankless models about 15 to 20. Warning signs include rust-colored water, a rumbling noise and water around the base. Read how to find your water heater's age.
How this varies by climate and region
| Factor | Where it matters | What it does | What helps |
|---|---|---|---|
| Heat and humidity | Gulf Coast, Southeast, much of the South | Long cooling seasons make AC run harder, and humid air stresses systems | Keep indoor humidity under 60%, ideally 30% to 50% (EPA), and service the AC yearly |
| Salt air | Coastal areas everywhere | Accelerates corrosion of outdoor equipment (Bryant) | Routine professional service, and keep the unit clean and clear |
| Hard water | Much of the east-central and western U.S. | Scale shortens the life of equipment and raises heating costs (USGS) | Flush the water heater and descale as the manual says |
| Cold winters | Northern states and mountains | Longer heating seasons keep heating equipment running more (Bryant) | Annual professional service and fresh filters |
| Lightning and surges | Storm-prone regions, but surges happen anywhere | A surge can damage, degrade or destroy electronic equipment (ESFI) | A whole-home surge protective device at the panel |
| Wildfire smoke | Wildfire-prone regions and areas downwind | Smoke loads filters faster | MERV 13 filters if your system can take them, and more frequent changes during smoke events (EPA) |
The Electrical Safety Foundation International notes that most surges start inside the home, and that no surge protection can handle a direct lightning strike. Manufacturers' guidance differs, so check your warranty and manual for climate-related conditions.
Get more years out of what you own
- Clean refrigerator coils, dishwasher filters and dryer vents on a schedule
- Replace washer hoses every three to five years and check supply lines for bulges or leaks
- Keep AC filters fresh and the outdoor unit clear of plants and debris
- Flush the water heater and check its anode rod
- Level the washer and refrigerator so they do not vibrate
- Register new appliances and keep receipts for warranty claims
How to know your appliances' ages
The model and serial number on each appliance's nameplate usually encode its manufacture date, and the format differs by brand. Photograph every nameplate once and keep the photos with your records. Our guide to finding an appliance's serial number shows where the label sits on common brands.
Track your appliance ages in Steadwell
Add each appliance to Steadwell with its model and serial number and the app tracks its age against an expected lifespan, flagging it as it ages or passes that mark. AI scan reads the nameplate from a phone photo on the Plus and Pro plans, the warranty tracker keeps coverage dates, and recall alerts check your appliances against federal safety recalls.
Frequently asked questions
How long do major home appliances last?
Roughly: refrigerators 9 to 14 years, dishwashers 9 to 10, washers 8 to 12, dryers 10 to 14, electric ranges 13 to 15, gas ranges 15 to 17, central AC 12 to 20, furnaces 15 to 25 and tank water heaters 8 to 12. Sources differ, and climate and maintenance move any appliance toward either end.
When should I repair an appliance and when should I replace it?
Consumer Reports' rule of thumb is that a repair costing more than half the price of a new appliance is probably not worth it. Costlier models stay worth repairing for longer, because a typical repair is a smaller share of their value.
Why do appliances in some regions fail sooner?
Heat, humidity, salt air, hard water, cold winters and power surges all add wear in different parts of the country. Regular cleaning, annual service on HVAC and a whole-home surge protective device help.
How do I find out how old an appliance is?
Find the nameplate (inside the door, on the back or side, or under the lid), read the serial number and decode the date. Manufacturers use different formats, so check the manufacturer's website or scan the label with Steadwell.
Is it worth buying an extended warranty?
It depends on the appliance's price and the plan's terms. Consumer Reports found that nearly half of people who bought refrigerator extended warranties never used them. Read what is excluded, compare the cost with the likely repair bill, and check whether your homeowners policy or a credit card already covers it.
