As home inspectors, we have seen firsthand how long various household appliances typically last. When you buy a new home a common question is: how old are these appliances? And, how long can I expect it to last? Here’s a general guide on the lifespan of common household appliances and tips on how to extend their life.
Kitchen Appliances

Refrigerators: 10-20 Years

Refrigerator appliances

The average refrigerator lasts around 10 to 15 years, though some high-end models can push 20 years with proper care. The key to longevity is regular maintenance—cleaning the coils annually to prevent overheating and ensuring door seals are tight to maintain energy efficiency.
**Pro Tip:** Keep your fridge at the right temperature (around 37-40°F) and avoid overloading it, which can strain the motor.

Washing Machines: 8-12 Years

Washing machine appliances
Washing machines typically last 8 to 12 years. Front-load washers tend to have a slightly shorter lifespan due to more wear and tear on the door seal and drum. Regularly cleaning the filter and leaving the door open after washes to prevent mold growth can help extend its life.
**Pro Tip:** Balance your loads to avoid overloading, which puts additional stress on the machine’s motor and drum bearings.

Dishwashers: 7-12 Years

Dishwashers usually have a lifespan of 7 to 12 years. Hard water can shorten their life by causing mineral buildup, so using a water softener or cleaning with vinegar occasionally can help. Regularly inspect and clean the filter and spray arms to ensure optimal performance.
**Pro Tip:** Run hot water in the sink before starting the dishwasher to ensure the initial fill is hot, reducing strain on the heating element.

Ovens & Ranges: 10-15 YearsMicrowave Oven

Ovens and ranges generally last about 10 to 15 years. Gas ranges tend to outlast electric ones by a few years. Keep the oven clean to avoid grease buildup, which can damage internal components over time. Check the door seal regularly to ensure it’s airtight.
**Pro Tip:** If the oven’s temperature becomes inconsistent, it might be time to replace the thermostat, which is cheaper than buying a new oven.

Microwaves: 5-10 Years

Microwaves typically last 5 to 10 years. While they’re relatively inexpensive to replace, proper use can stretch their lifespan. Avoid slamming the door, as this can damage the door switches. Also, never run the microwave empty as it can cause significant damage.
**Pro Tip:** Keep the interior clean to prevent food particles from absorbing energy, which can cause hotspots and shorten the microwave’s life.

Water Heaters: 8-12 YearsWater Heater

Traditional water heaters last around 8 to 12 years, while tankless models can last up to 20 years. Regularly flushing the tank to remove sediment buildup can prevent corrosion and extend its lifespan. Check the anode rod annually, as it helps prevent tank rusting.

**Pro Tip:** Insulate the tank and pipes to reduce energy consumption and prolong the heater’s life.

In conclusion, while these estimates give you a good idea of what to expect, the longevity of your appliances largely depends on how well you maintain them. Regular inspections, cleaning, and following manufacturer guidelines can add years to your appliances, saving you money and hassle in the long run.

As a home inspector, I always recommend keeping a maintenance schedule to ensure your appliances are in top condition. Not only will this extend their life, but it will also keep your home running smoothly.

These photos and insights should help you better understand the lifespan of your household appliances. Taking a little time for regular maintenance can go a long way in making sure they last as long as possible!
