How Long Common Household Appliances Usually Last
Appliances rarely fail on a precise birthday, but they do follow useful life ranges that make repair decisions easier. As a practical rule of thumb: refrigerators often last 10-15 years, dishwashers 8-12, washing machines 10-14, dryers 10-15, electric and gas ranges 13-18, over-the-range microwaves 7-10, tank water heaters 8-12, central air conditioners 12-17, and furnaces about 15-20 years. The closer an appliance is to the upper end of its range, the more cautious you should be about sinking money into major parts.

Common Symptoms
- You are comparing a repair quote against the age of the appliance
- The unit still works but has become noisy, inefficient, or unreliable
- Multiple wear parts have failed within a short period
- Replacement parts are getting expensive or hard to source
- You want to budget for replacement before a full failure disrupts the house
Most Likely Causes
- 1
Usage Intensity
A dishwasher run twice daily or a dryer used for a large family wears out faster than the same machine in a smaller household. Service-life ranges assume average use, not heavy commercial-style duty at home.
- 2
Maintenance History
Neglected coils, clogged filters, scale buildup, and worn hoses shorten life dramatically. Appliances that get basic maintenance often outlast the average range by several years.
- 3
Water Quality, Heat, and Electrical Stress
Hard water attacks water heaters, dishwashers, and washing machines. Voltage fluctuations, poor ventilation, and high ambient heat shorten life for electronics-heavy appliances and refrigerators.
- 4
Repair Severity
A minor part like a thermal fuse, igniter, or inlet valve does not mean the machine is done. A sealed-system refrigerator problem, transmission failure, or major control-board failure on an old unit is a different decision.
- 5
Parts Availability and Efficiency Changes
Older appliances may still be physically repairable, but discontinued parts and poor energy efficiency change the economics. Sometimes the age decision is driven by supportability, not just wear.

Quick DIY Checks
Do not keep nursing an aging appliance that shows electrical burning, active leaking near live components, gas smell, or repeated breaker trips. Those symptoms override normal lifespan math.
If you inspect age tags or maintenance areas, disconnect power first and shut off gas or water supplies where appropriate. Age planning should not turn into unsafe exploratory work.
- 1Step 1 - Find the appliance age before making any repair decision. Use the serial plate, model tag, or manufacturer date code rather than guessing based on when you bought the house.
- 2Step 2 - Compare the appliance to its typical life range. If it is in the first half of that range, repair is usually favored unless the failure is catastrophic. If it is near or beyond the upper range, be more selective.
- 3Step 3 - Separate minor fixes from major-system failures. A $20-$120 part on a mid-life machine is a very different call from a compressor, tub bearing, transmission, heat exchanger, or control-board failure on an old one.

Repair vs Replace
Age should guide the decision, not make it automatically. Appliances in the early or middle part of their lifespan are usually worth fixing for ordinary failures. Older units near the upper end of their expected life should be evaluated more critically when the repair involves major mechanical or electronic systems.
Est. Repair Cost
$20-$400 for common minor-to-midsize repairs, depending on appliance and part
Est. Replacement Cost
$400-$3,500+ depending on the appliance category and features

Frequently Asked Questions
- How long do refrigerators usually last?
- A typical refrigerator lasts about 10-15 years. Units with clean coils, good door gaskets, and moderate kitchen temperatures often land on the upper half of that range.
- How long do dishwashers and washing machines usually last?
- Dishwashers are often in the 8-12 year range, while washing machines commonly land around 10-14 years depending on water quality, load size, and maintenance habits.
- When is an old appliance still worth repairing?
- When the problem is small, the machine has otherwise been reliable, and the repair does not involve a major core system. Age matters most when you are facing expensive repeat failures or a large single repair.
- Do modern appliances last less time than older ones?
- Often yes in some categories, largely because modern machines use more electronics, thinner materials, and tighter efficiency designs. The tradeoff is lower energy and water use when they are working properly.
