Appliance Life Expectancy: What You Need to Know

Knowing how long your home appliances are expected to last can help you plan your replacements and set a budget accordingly.

In this article, we’re going to discuss the average life expectancy of three of the most important appliances:

● Water heaters

● Air conditioners

● Furnaces

So let’s get started.

Appliance Life Expectancy: What Every Homeowner Needs to Know

Water Heaters

The average lifespan of a typical water heater is about 10 years. A traditional water heater will last anywhere between 8 to 12 years.

However, its useful life varies as it depends on various factors, including its type, maintenance, and the quality of the unit. The quality of the water inside a water heater also affects its lifespan.


The average lifespan of a furnace is between 15 to 20 years. However, your furnace will only last that long if it is well-maintained.

There are many factors that affect the lifespan of your furnace. If you are diligent with repairs and get your furnace inspected and maintained annually, it will complete its functional life.

However, once your furnace reaches the 15-year mark, you should start looking for a replacement as repairing it at this point won’t be practical.

Air Conditioning Units

The average lifespan of air conditioning units is 15 to 20 years. If your air conditioning unit is well-maintained, it can last for more than 20 years.

However, the exact lifespan depends on a number of factors, including the installation quality, the climate in your religion, air quality, thermostat settings, and regular maintenance.

How to Extend the Life of an Appliance

As a homeowner, you’d be glad to know that you can extend the life of any appliance through a regular maintenance schedule.

So, let’s say if the average life of an appliance is 5 years, regular maintenance may extend its functional life to 7 years.

Here’s how:

1. Regular Cleaning

Cleaning your appliances is the best way to make sure they last longer. It is important to clean your appliances every month as they can collect dust, debris, grease, char, and other contaminants over time.

When not cleaned, these contaminants will destroy your appliances and even cause corrosion. You can use appliance-cleaning liquids, degreasers, and steam to rid them of these contaminants.

2. Regular Inspection and Maintenance

Home appliances such as air conditioners and furnaces that work all year round require special care. Regular inspection by a professional can help you identify any underlying issues so you can have them repaired timely.

Hire a professional to inspect and maintain your home appliances once or twice a year. This way, you can extend their useful life and even keep yourself safe from any hazards.

3. Filter Replacements

HVAC systems run all year round, which means they collect all the dust, pet dander, and other contaminants in the air.

Therefore, you need to change the filters of your HVAC system every month to make sure there’s no overload on the system and you have clean air to breathe in.

Experts suggest changing your air filters once a month to prevent overload on the system.

Get Your Appliances Inspected

The average life expectancy of an appliance won’t matter if you don’t have a regular maintenance schedule.

Getting them inspected by a professional can even extend their functional lifespan.
