Are you tired of taking care of your home furnace? A furnace is one of the most important elements of your home.

If yours has begun sputtering and spitting, you’ll want to know the answer to the question above. Wondering how long the furnace will last can be frustrating. Often the condition of the furnace and how you use it can determine how often you’ll need to replace it.

But how often you’ll need to replace your home furnace can be different than others. We’ve broken down the main elements in this article.

Average Lifespan


The average lifespan of a home furnace is between 15-20 years. The actual lifespan of a home furnace depends on many factors such as make and model.

If a home furnace is adequately maintained and receives annual inspections and tune-ups, it can last much longer than the industry average and provide reliable heat for a much longer time.

Additionally, investing in newer, energy-efficient models will help maximize the life of the furnace and save money on energy costs.


If your home is running constantly, that’s going to cause an increase in wear and tear on not just the furnace but its components as well. The longer and harder you work it, the sooner you’ll need to get a new furnace installed.

It’s important to remember that even if your furnace appears to be running smoothly, you should still get it checked out every few years by an HVAC professional.


Furnace Lifespan

A home furnace can last longer, anywhere from 10-25 years depending on proper maintenance. When you need a new furnace, it’s usually due to insufficient maintenance throughout its lifetime.

Proper maintenance and key repairs along the way can keep your home furnace working efficiently and safely. To get the most out of your furnace, make sure you’re:

  • Changing the filter regularly
  • Cleaning the interior of the furnace
  • Having the furnace inspected once a year

This prevents small issues from turning into major repairs and saves you from needing to buy a new furnace prematurely. In other words, with proper care, a home furnace can last for more than two decades.

Signs of Wear

Even when the furnace is well-maintained, there will be signs of wear that can alert you when it may be time to replace your furnace. These signs can include a higher energy bill, irregular or loud noises, or low heating output. If you are experiencing any of these signs, it may be time to contact a professional to help gauge how much life it has left.

A major upgrade could include a high-efficiency furnace that is more efficient and is more likely to reach the desired temperature faster. A newer system is also less likely to fail unexpectedly and will be a much more reliable system overall.

Upgrading your furnace will usually cost more than repairing an older unit. But it also provides greater energy savings and improved comfort in your home. Choose a website with furnace replacement services to see a wide range of the kinds of furnaces available which can be useful for your upgrade.
