Age Sets the Context
A 10-year-old furnace with a failed igniter is a repair. An 18-year-old furnace with a failed inducer motor, a history of breakdowns, and rising bills is a replacement conversation. Age does not decide alone, but it frames every other factor.
The Safety Trump Card
A cracked heat exchanger ends the debate. No repair makes a cracked exchanger safe except replacement of the exchanger or the furnace. When safety is on the table, cost comparisons take a back seat.
Adding Up the Real Costs
Beyond the quote, consider: how many repairs in the last two years, how much higher are winter bills than they should be, and how much is reliability worth on the coldest nights. A new furnace buys a decade-plus of not thinking about it.

Questions About Furnace Repair vs Replacement
Is there a rule of thumb?
Multiply the repair cost by the furnace age. If it exceeds the replacement cost, replacement usually wins. It is a guide, not a law.
Can I replace in stages?
The furnace is one integrated system. Partial replacements rarely make sense except for specific warranty-covered parts.
How long does replacement take?
Most residential replacements complete in one day, with heat back by evening.
