Home / How Long Do Furnaces Generally Last?

Think you need to replace your furnace? You may be surprised to learn that they can last anywhere from 10-20 years. How long a furnace lasts depends on a variety of factors, including the quality of the unit, how often it’s used and how well it’s maintained. If you’re wondering whether or not your furnace is nearing the end of its lifespan, keep reading for more information.


Knowing the furnace’s life expectancy is crucial for homeowners since a furnace is one of a home’s important components. The lifespan of a furnace is influenced by a number of elements, such as its special characteristics, the time since it was made, and how well it has been maintained. If the furnace hasn’t been updated in the recent few years, it’s probably towards the end of its useful life for someone living in an older home. Knowing how to recognize subpar installation or careless maintenance can help homeowners determine if their furnace still has life in it or whether it needs to be replaced.


What Are The Factors That Affect The Lifespan Of A Furnace?

The lifespan of a furnace can depend on a variety of factors, including the quality of the furnace, how often it is used, and how well it is maintained. Generally, furnaces last an average of 15 years. However, if the furnace is subjected to a lot of use or if it is not properly maintained, its lifespan may be shorter.


Quality Of The Furnace

A furnace’s quality is important in determining its lifespan. A good-quality furnace will last longer than a furnace of lower quality. There are many factors that go into the quality of a furnace, such as the type of materials used, the construction, and the warranty.


One important factor that affects the quality of a furnace is the type of materials used. Some furnaces use cheaper materials that may not be as durable as higher-quality materials. This can affect the lifespan of the furnace.


Proper Installation

Proper installation is key to ensuring your furnace has a long lifespan. If the furnace isn’t properly sized for your home, it will cycle on and off more often, which can decrease its lifespan. Additionally, if the ductwork isn’t properly designed and installed, the furnace can work harder than necessary, leading to an early failure.


A well-constructed furnace will last longer than a poorly-constructed furnace. Factors that contribute to good construction include using high-quality materials and ensuring that all components are securely attached. If a furnace has been installed incorrectly, it can lead to a shorter lifespan.

The Warranty

The warranty is also an important factor in determining the quality of a furnace. A good warranty will protect the purchaser from any defects in the furnace. It is important to read the warranty carefully to make sure that it covers all possible problems with the furnace.


Regular Maintenance

One of the most important factors in determining how long a furnace will last is by ensuring that it receives regular maintenance. A furnace that is properly taken care of can last up to 20 years, while one that isn’t may only last 10 years. By having a professional come out and clean the furnace twice a year, you can help to ensure that it runs as efficiently as possible and lasts as long as possible. It’s also important to have the filters regularly replaced as well.


This can help to keep your furnace running smoothly and prevent it from needing more costly repairs down the line. Regular maintenance is key to ensuring that your furnace lasts for as long as possible and continues to provide you with efficient heating for years to come.


The Environment

The environment in which the furnace is located can also affect its lifespan. An outdoor furnace that is exposed to extreme weather conditions may need more frequent servicing or replacement than one located indoors in controlled temperatures. Additionally, if the furnace runs on natural gas or propane, it can be affected by leaks from pipes and tanks, which can reduce its lifespan.


So, how long do furnaces generally last? The answer to this question may vary depending on the make and model of your furnace, as well as the quality of installation and maintenance. However, a good rule of thumb is that most furnaces should last around 15 years.
