10 Things That Impact the Longevity of Your Furnace – Part 2

One of the most important components of your home is your furnace. It is responsible for keeping your home warm and comfortable during the winter months. But, if your furnace isn’t maintained properly, its lifespan can be significantly shortened. 

In this article, we will continue to explore five more things that can have an impact on the longevity of your furnace.

6. How Often You Use Your Filter

If you use your furnace regularly, it will not last as long as if you only use it occasionally. The more often you use your furnace, the more wear and tear it will experience.

7. The Type of Water

If you live in an area with hard water, your furnace will likely not last as long as if you live in an area with soft water. Hard water can damage the heat exchanger in your furnace, which will shorten its lifespan.

8. The Size of your Furnace

As with any appliance in your home, the size of your furnace will have an impact on its lifespan. A too-small furnace will have to work harder to heat your home, which will shorten its lifespan. Conversely, a furnace that is too large for your home will not run as efficiently, which will also shorten its lifespan.

The best way to determine the size of furnace you need is to have a professional HVAC contractor perform a load calculation on your home. This will take into account the size of your home, the insulation levels, the number of windows, and other factors to determine the BTU (British Thermal Unit) output that you need.

Once you have the BTU output that you need, you can then choose a furnace that is sized appropriately. It is always better to err on the side of a furnace that is too large as opposed to one that is too small.

9. The Vents in Your Furnace

The vents in your furnace play a critical role in the efficiency of your heating system. If they are not properly maintained, they can cause your furnace to work less efficiently and even shorten its lifespan. In order to keep our furnace working at its best, it is important to regularly check and clean our vents.

10. The Age of Your Furnace

Your furnace’s age is just one of many factors that will impact its longevity. However, it’s important to keep in mind that an older furnace may not be as efficient as a newer model. If your furnace is starting to show its age, you may want to consider replacing it with a newer, more energy-efficient model.


The longevity of your furnace can be impacted by a variety of factors, such as how often you use your filter, the type of water, the size of your furnace, the vents in your furnace, and the age of your furnace.

By understanding these factors and taking the necessary steps to ensure that your furnace is properly maintained, you can extend the lifespan of your furnace and help ensure that your home is comfortable and energy-efficient.
