How Long Should A Furnace Last?

A furnace’s lifespan can vary greatly based on a number of factors, so let’s investigate how you can extend your furnace lifespan.

There’s no conclusive answer of how long a furnace will last as it can vary on a case by case basis. However, we can tell you that the average furnace lifespan is 15-30 years, and in some cases a furnace can even last up to 40 years. We’re here to share with you the factors that affect a furnace lifespan, signs of a necessary replacement, and ways you can prolong your furnace’s life.

What affects a furnace’s lifespan?

Numerous factors can affect how long your furnace will last, here are the most prominent ones:

Lack of maintenance: Regular maintenance is necessary to extend your furnace lifespan. Hire a certified and trained HVAC technician to complete regular cleanup and maintenance of your furnace. A professional can complete minor repairs during the maintenance process that will prevent serious issues later down the line.

Improper sizing: An improperly sized furnace will affect the energy efficiency and comfort of your home. An oversized furnace will turn on and off constantly, thus wearing itself out, while a furnace that is too small will have to overwork itself to heat your home. This will likely result in your furnace’s life ending prematurely.

Poorly done installation: When air ducts are poorly designed, sized, or sealed it will restrict airflow throughout the home and will affect the furnace’s performance greatly. If venting and fuel lines aren’t installed properly this can reduce the furnace’s lifespan.

Signs Your Furnace’s Life Is Nearing Its End

Before a furnace reaches the end of its life there are typically some warning signs.Watch out for warning signs and replace your furnace proactively so you won’t have to spend any cold winter nights without heat. These warning signs include:

  • Expensive repairs
  • A significant increase in your monthly utility bills
  • Frequent service calls
  • Declining performance
  • Cold air pockets throughout the house
  • Poor air quality
  • Loud noises

Extending Furnace Lifespan

Extending your furnace’s lifespan is done through regular maintenance and service. Here are some things that you can do to keep your furnace in its best shape and maintain its efficiency level all while extending its lifespan:

  • Clean the dirt, dust and debris from the filters, motors, and heat exchanger.
  • Replace the air filter when it gets dirty and clogged up.
  • Have your ductwork cleaned and sealed.
