How Long Does A Furnace Last?

When it comes to furnace replacement, many homeowners have no idea how long their furnace will last. The typical life expectancy of a furnace is around 15 years, but this can vary depending on the type of furnace and the amount of use it gets. In this post, we will discuss the average lifespan of different types of furnaces, as well as some factors that can affect how long your furnace lasts.

Furnace Lifespan Depending On Types


The most common type of furnace is a gas furnace, which typically has a lifespan of 15-20 years. If you have an oil furnace, it will likely last about 10-15 years. Electric furnaces tend to last the longest, with a lifespan of 20-30 years.

Factors That Affect Furnace Lifespan

However, these are just averages and your furnace may not last as long or could even last longer than these estimates. There are a few factors that can affect how long your furnace lasts, such as:

  1. The quality of the furnace: If you buy a high-quality furnace, it will likely last longer than a cheap one.
  2. Maintenance: Properly maintaining your furnace can help it last longer. This includes regularly changing the air filter and having it serviced by a professional every few years.
  3. Usage: If you use your furnace more often, it will likely wear out faster than if it’s only used occasionally.
  4. Climate: The climate you live in can also affect how long your furnace lasts. For example, furnaces in colder climates tend to have shorter lifespans than those in milder climates.
  5. Age: Older furnaces are more likely to need replacement sooner than newer ones.
