What Is The Average Lifespan Of A Furnace?

Many factors are considered when determining the lifespan of a furnace. It is beneficial to understand these factors that affect the furnace’s life and some methods for delaying furnace replacement to make it last as long as possible.

A Furnace's Average Life Expectancy

Furnaces can last longer than 40 years, which is extremely rare, but the average lifespan is 15 to 30 years. Your furnace should easily last over 15 years if you schedule annual maintenance with a furnace tune-up service in Battle Ground, WA.

You may need to make some basic repairs to your older furnace, just like you would to your car or any other HVAC appliance. Some people prefer to buy a new model even if a minor repair is needed on a furnace that’s out of warranty, through a furnace replacement service in Battle Ground, WA. Others may make several repairs before replacing the old furnace.

The Factors that Affect the Life Expectancy of a Furnace

  • The furnace is not sized correctly

    Heating and air conditioning systems can become less energy-efficient if the furnace is not correctly sized. In addition, it may decrease the lifespan of the furnace.

  • Improper installation

    A furnace’s lifespan depends on the way it is installed. It is possible to have problems with furnace performance and reliability when ductwork is not properly designed, sized, and sealed. Venting and faulty fuel lines can also affect performance and reduce furnace longevity.

  • Temperatures set too high

    Thermostat settings too high or low can damage components, shorten the furnace’s life, or result in an expensive or inconvenient service call. Ideally, set the thermostat between 60⁰ and 80⁰ Fahrenheit.

  • Maintenance performed regularly

    Maintaining a furnace regularly can extend its life and improve its performance. A certified technician should do regular cleaning and maintenance on your heating system. In addition to improving performance, they can prevent bigger problems in the future.

Extending the Life of a Furnace

Keeping your gas furnace clean, maintained, and serviced is the best way to prolong its lifespan. It can ensure your furnace is performing efficiently and prevent premature failure.

Maintain a clean filter by freeing it from dirt, dust, and other particles. Air filters in furnaces should be checked and cleaned regularly. Instead of installing an air conditioner with your new furnace, consider a heat pump. The furnace will have to do less work because it will run on dual fuel.
