The age of your current furnace. If it’s nearing the end of its lifespan, replacing it before it fails outright can save you the headache of a mid-winter breakdown.

How much your current furnace costs to run. If your energy bills have been creeping up, an aging or inefficient furnace could be the reason. A newer unit often pays for itself over time in energy savings.

How often you’re calling for repairs. If your furnace is in the shop every other month, replacement is often the smarter long-term move.

Whether your home actually stays warm. If you’re constantly cold even when the furnace is running, that’s a sign your system isn’t up to the job anymore.
