The lifespan of a home furnace can vary significantly based on factors such as the type of furnace, maintenance practices, and usage patterns. Generally, gas furnaces last around 15 to 20 years, while electric models may last a bit longer. Regular maintenance, including filter changes and annual inspections, can extend the life of your furnace and improve efficiency. It's also important to consider signs of wear and tear, which can indicate when it's time for a replacement. Curious about how to keep your furnace running smoothly or when to consider an upgrade?
