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, as well as advancements in technology that might make a newer model more appealing.
