“That cannot be determined without an onsite inspection and diagnostics by a qualified technician. Sorry. It can range from no charge, under warranty, to many hundreds.
If the furnace is over twenty years old, make sure the heat exchanger is intact, not rusted or acid-eaten. It’s probably not worth the cost to thoroughly assess at that age, and should be replaced instead of repaired, to eliminate the risk of heat exchanger failure and its close cousin, carbon monoxide death.”
