A contractor called out for furnace repair in Jackson County has to decide early on what actually drove the failure. 49 severe weather events were recorded in Jackson County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event here, not a steady operating pressure on the equipment. That matters for diagnosis because it takes age, poor installation, or missed maintenance off the table as excuses and puts them at the front of the list. A heat exchanger cracking or a control board failing in a county with a record like this points a contractor toward how old the system is and how it was set up, not toward what the sky has been doing.
Furnaces in houses built this long ago have often been replaced once or twice over, which means a unit running today was chosen to fit a house rather than built alongside it. Half the homes in Jackson County, Indiana were built in 1978 or earlier (2020-2024 ACS 5-year). When a contractor opens that equipment, the question is whether the heat exchanger, draft inducer, or control board it takes still has an active supply chain. Some do. Some require sourcing from distributors who stock older parts specifically, and that search changes the repair timeline before any labor is scheduled.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the center of the furnace cabinet and is the piece a contractor looks at early in a repair call. Cracks or stress in it let combustion gases into the airstream. The burner assembly sits just below it, and a misfiring or dirty burner is one of the more common reasons a furnace stops producing heat.
The blower motor and its fan wheel sit in the lower half of the cabinet and push conditioned air into the supply ducts. The igniter and flame sensor work as a pair near the burner: the igniter starts combustion and the sensor confirms it happened. The control board ties those components together, and a fault there can mimic failures in several other parts.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply to your specific system and situation.
