Ask a proA crack can let combustion gases into the air. If one is found, the furnace is shut down and you’re told exactly why.
Older frame homes lose heat through walls and windows. Sealing and insulation help any furnace keep up.

Schedule a fall safety check every year for older furnaces and boilers, and keep CO alarms on every floor.
When repairs pile up, ask for a replacement estimate alongside the repair.
