How Long Does a Furnace Last? Answered
Data shows that the average furnace will last no longer than 30 years. However, there are a few different factors that will ultimately impact the longevity of your furnace.
First and foremost is the quality of the installation itself. If the furnace installed was a high-quality unit for its time, and the installation procedure was done well so that there are no negative effects from long-term operation, then the furnace will last longer.
In addition to first-time installation is also the question of ongoing maintenance. Obviously, furnaces that are well-maintained and repaired as soon as something begins to go wrong are the ones that will have the maximum lifespan.
How to Maintain a Furnace Well
So now that you have a better idea of what a gas furnace lifespan typically looks like, let’s start talking about how you can extend the lifespan of your unit with the right care and maintenance.
The first thing that you need to take care of is the blower. This is the item that will send air through your ventilation system once heated. The blower’s blades need to be vacuumed and brushed regularly so that dirt and dust do not build up on them. If there is too much buildup, that will affect the efficacy of the blower.
Next, you’ll also want to regularly inspect the flames of the burner. These flames should be even and blue. If they are not, then that is indicative of a dirty burner that should be professionally cleaned by a heating repair service as soon as possible.
Another maintenance tip that’s relatively easy is changing the furnace filter. Filters get dirtier over time, and when they get dirty they clog up the airflow, making your blower work overtime. Change this whenever you see it getting significantly dirty.
Last but not least, also inspect and test the drive belt that drives the motor. If it is cracking or fraying, it’s time to replace the belt before it snaps and causes damage to the unit.
