If you’re wondering how you can keep your furnace in top condition, it’s important to know the factors that affect its expected lifespan. This will help you decide when to replace your furnace. Keeping your furnace well-maintained also helps you spot the factors that affect the longevity of your installed furnace. 



To understand more about your furnace, Climate Systems Heating and Air Conditioning shares these insights:


How the Lifespan of Your Furnace Varies


Furnaces typically last between 15 and 20  years, though it depends on certain factors such as the quality of the unit and how often it’s used. Not all furnaces are made the same; for instance, older ones that have heavy cast-iron heat exchangers can last up to 30 or 40 years, though they aren’t very efficient. An electric furnace or an active solar heating system will only last around 20 years, while gas furnaces and boilers have varied lifespans of 15 to 30 years. 


Other Factors That Affect Your Furnace’s Lifespan



  • Faulty installation and ventilation – When installing a furnace, your hired contractor should make sure it has proper ventilation and clearance. Having inadequate airflow and/or too much moisture can damage its heat exchanger and negatively affect its lifespan. 


Make sure your chosen HVAC contractor has the proper licenses and credentials so that you can be confident that your furnace is properly installed. Doing so also ensures that you get a warranty for the unit and that repair costs will be covered should you ever need it.


  • Age and model – Some brands are better than others, so make sure to go for the ones that are high-quality. Older model furnaces tend to have a shorter lifespan, so always go for the latest model on the market that you can afford.
