How Long Do Appliances Typically Last? A Quick Overview


Most homeowners rarely give a thought to their appliances, until one of them breaks down unexpectedly. However, most people tend to replace their major home appliances before the end of their lifespan if they want to buy more energy-efficient models.

But, most people purchase new appliances when the need arises, and this shows the importance of knowing the lifespan of your appliances. This can greatly help you budget and plan accordingly for your new appliances. Generally, the average lifespan of most appliances in our homes is around 10 – 15 years. However, you can easily lengthen the lifespan of your appliances through regular maintenance and cleaning, as well as proper use.

In this post, we shall do a quick review of all the major appliances in our homes to check their lifespan.

HVAC systems and furnaces

An HVAC system requires regular and proper maintenance for it to function efficiently. All in all these systems do have a lifespan of 15 – 25 years. On average, a furnace can last up to 20 years, an AC unit for 15 years, and heat pumps for 16 years. Tankless water heaters, on the other hand, can last over 20 years. The average lifespan of a gas or electric water heater is around 10 years. While thermostats have an average lifespan of 35 years, they are mostly replaced before the end of the lifespan because of technological improvements.


On average, refrigerators can last around 10 – 13 years. However, your refrigerator can last longer with proper maintenance, like cleaning the dust from the condenser coils twice a year. The condenser coils for older models can be found at the back—and they are mostly painted in black. Newer models have their condenser coils mounted at the bottom. It’s very easy to clean the condenser coils—so long as you have a coil brush. Also, you can vacuum the dust away with a vacuum cleaner—but you should be careful not to damage the other parts of the fridge.


There are two freezer options available in today’s market—chest or upright models. The average lifespan of a freezer is around 11 years, although they can last up to 20 years. However, it’s possible to maximize the efficiency and longevity of your freezer. To do this, you will need to invest in a freezer model equipped with an automatic defrosting cycle. But, you don’t have to fret if your freezer doesn’t have the automatic defrost cycle—you can manually defrost your freezer regularly. Generally, your freezer shouldn’t have more than ¼ inch of frost.


The Lake Mary appliance Repair Company experts say that a well-functioning dishwasher provides homeowners with lots of savings in energy, water, and time. However, these household appliances have one major challenge—a short lifespan. On average dishwashers can last around nine years. Modern dishwashers have better energy and water consumption. That means the shorter lifespan provides an opportunity for homeowners to get modern and efficient dishwashers.


The average lifespan of a microwave is 9 years. These appliances also don’t last long like dishwashers. However, to keep your microwave oven in a good condition and functioning well, you should regularly clean the inside and outside of the appliance. Besides, always follow the indicated instructions, and ensure its door closes well.

Washing machines

According to the NAHB, the average lifespan of a washing machine is around 10 years. To improve the longevity of your washing machine, always wash if you have a full load. This helps to reduce the number of cycles your machine runs every year. Also, it helps to save energy and water. Also, regular maintenance, which includes cleaning the filter or trap, as well as replacing the hoses whenever needed, can help to improve the lifespan of the washer.


Both gas and electric dryers have the same lifespan—13 years on average. However, observing some good maintenance tips, like cleaning the ducts and lint filter can help your dryer to be more efficient and safer to run, and improve its lifespan.


Of all the appliances in your kitchen, gas ranges have the longest lifespan—an average of 15 years. Electric ranges, on the other hand, have an average lifespan of 13 years—that’s according to the NAHB (National Association of Home Builders). A range hood, which is installed over the cooking range to trap cooking odors and grease particles, can last up to 14 years.

Garbage disposals

Garbage disposal plays an important role in our home—it grinds food waste into small particles that can be flushed down the drain easily. Moreover, they are some of the appliances that do the most intensive work in our homes—despite their small size. Because of this, garbage disposals have an average lifespan of 8 years, although they can last up to 12 years with proper and regular maintenance.

Bottom Line

While each appliance discussed above has its set lifespan, keeping your appliance in a good condition and using it properly goes a long way towards lengthening its lifespan. Besides, regular maintenance and inspection by a professional appliance technician is essential if you want your appliances to last long.
