How Long Does A Gas Furnace Usually Last?
How long does a gas furnace last? What exactly does it do you or your home? Your gas furnace is one of the most important appliances in your home. It is a heating appliance used to heat and circulate air to keep your home comfortable during times when the weather isn’t hospitable.
The average lifespan of a typical gas furnace is between 18 and 20 years. You can extend the furnace’s operation to 25 or 30 years with proper maintenance. However, if you don’t properly maintain your furnace, you can expect it to fail in as little as 10 years. Many homeowners aren’t completely aware of their furnace’s age and the extent of its use. You can find the manufacturer serial number on the inside of the furnace cover. Then, call a heating professional to get a manufacturing date using the serial number. It might be time to consider a furnace replacement if you’re approaching or past the 15-year mark and have put a lot of repair into your gas furnace.
What factors affect how long your furnace will last?
Here are 3 factors affecting the life span of your gas furnace:
The first factor is the quality of your gas furnace. This depends on many factors such as the manufacturer, the level of workmanship, and the materials used in its construction.

2. Wear and Tear
The second factor is the wear and tear of your gas furnace. How often do you use your furnace? Do you live in a low-temperature area? If so, you’re likely to use your gas furnace more often than something living in warmer climates.
The third factor is the maintenance of your gas furnace. Regular maintenance is needed in order for your gas furnace to operate optimally. Just like any other piece of household equipment, maintaining your gas furnace ensures its longevity.
