One of the biggest questions for homeowners is when to invest money in a new furnace. You may ask now – how long does a traditional furnace last? An average furnace is designed to perform for a period of 15 to 30 years. The lifespan also depends on the type of fuel used to heat your home. Although postponing the investment may seem ideal, it is important to replace the older systems before any dangerous breakdown happens. But how can you be certain you need a new furnace for your heating needs?

Keep reading to learn about the important signs you should watch for as your furnace nears the end of its lifespan.

The age of the furnace
If your furnace is 15 to 18 years or older, it is closer to its end than you may think. The average lifespan of a furnace ranges between 15 to 20 years, although it may vary depending upon its maintenance or upkeep.

Increasing utility bills
If you find an erratic increase in your energy bill, it may be a sign your furnace is not performing efficiently.

Uneven heating in different areas
If you experience uneven heating in different rooms, it is due to the design of your furnace. This is because an aged system may not be able to circulate heat evenly in different areas.

A huge amount of dust, soot or rust particles
If you notice more dust, soot or rust particles accumulating in your home, it could be an indication you need to invest in a new furnace.

Production of loud noise or rattling during operation
If your furnace is running louder than average or rattles while operating it can be because of cracks, leaks,or other problems.

Humidity issues
If you experience the air in your home to be dry, it can be because of a faulty furnace.

Identification of cracks or rust
If you identify cracks or rust in and around the furnace, you should think of replacing it. This problem generally occurs when the system ages over time.
