How Long Does a Furnace Last?

April 5, 2022

There is no specific answer for how long your furnace will last, but there are several factors that can have a major impact on the lifespan of your furnace. From the quality of the manufacturing to how often you maintain your furnace, there is a number of factors that can make a difference in the lifespan of your furnace.

Other factors include:

  • How hot or cold you keep your home
  • How often the furnace is running
  • Temperature extremes

All of these factors play a role in how long your furnace will last.

What is the Average Lifespan of a Furnace?

Typically, a furnace that has been well-maintained should last anywhere from 15 to 20 years. To ensure this type of lifespan, you need to complete annual maintenance and be diligent with repairing your furnace with quality parts. You should also keep in mind that there will come a time when a replacement furnace will save you money in the long run rather than paying for multiple repairs.

If your furnace is around 15 years old, you should take the time to begin looking at a new furnace, so you are prepared when a replacement is needed before it stops working. You can speak with experts at Jacob Heating & Cooling to learn more about the modern, energy-efficient options that are available and get an idea of what the replacement will cost you.

What Factors Reduce My Furnace Lifespan?

There are several factors that can reduce the lifespan of your furnace, including:

Poor Quality Furnace Installation

There are several reasons why poor-quality installation can affect the lifespan of your furnace. This is why it is crucial to work with the qualified HVAC experts at Jacob Heating & Cooling for your furnace installation needs. Without proper installation, you can end up with:

  • Low quality designed, sized, and sealed ductwork. This can lead to a lack of airflow that can affect not only your system efficiency but also your home’s environment.
  • Poorly installed fuel lines.
  • Low-quality drainage. This is especially important for high-efficiency furnaces.

Improper Furance Size

It is critical to have the proper size furnace for your home. For example, if you have a furnace that is too large for your home, it will shut off quicker than normal. The shorter cycles will cause excessive wear and tear on the parts of the furnace.

On the other hand, if the furnace is too small to accommodate your home, it will remain on for too long and will not heat the home efficiently. This will also lead to excessive wear and tear on your furnace parts.

Personal Thermostat Settings

It’s important to note that putting your furnace too high or too low can also cause your system to run more frequently, which in turn can reduce its lifespan.Skipping Routine Maintenance for Your Furnace
Just like with your car, your furnace requires regualr maintenance to keep it working efficiently. This can lead to damaging build-up on the fan blades, burners, and heat exchangers, which can reduce the lifespan of your furnace by restricting airflow from a dirty filter, causing the furnace to work harder to blow air.

It can also lead to an imbalanced fan that can affect the lifespan of the motors while also causing the heat transfer from the heat exchanger to be hindered, which can cause the system to work harder than necessary.

What are the Signs That I Need a New Furnace?

Even with the proper maintenance and use of your furnace, it will eventually need to be replaced. At Jacob Heating & Cooling, we recommend a replacement furnace when you begin to notice the following:

  • Increased or new noises are coming from the system.
  • Furnace producing uneven temperatures and can’t maintain the temperature on the thermostat.
  • The furnace is blowing cold air.
  • An increase in your energy costs, even with a high-efficiency system.
  • Requires frequent repairs with expensive repair bills.
