A buyer said an HVAC technician found multiple cracks in the furnace’s heat exchanger after closing; the inspector had called it old, operable and in need of service. Inspectors online said the exchanger is mostly hidden during routine checks.
Several commenters said the report’s “needs service” note should have prompted an HVAC contractor’s review during due diligence, before closing. Others recommended a second opinion and camera evidence of the reported cracks before approving replacement; one cited carbon-monoxide risk if the cracks were real. Another suggested checking the heat-exchanger warranty.
