A furnace that stops working in Bartholomew County is almost always telling you something about its age or how it has been serviced, not about what the weather has put it through. 57 severe weather events were recorded in Bartholomew County, Indiana between 2015 and 2024. At that rate, severe weather is an event in this county, not a constant. A contractor diagnosing a failed heat exchanger or a worn inducer motor here will look at installation quality and service history first, because those are what drive failures in a place where the atmospheric load on equipment stays relatively light. The weather record is real, but it does not shorten a furnace's life the way neglect does.
Ductwork in a house this old has seen whatever furnaces came before the current one, and those earlier systems shaped what fittings and connections are already in place. Half the homes in Bartholomew County, Indiana were built in 1979 or earlier (2020-2024 ACS 5-year). When a contractor opens a furnace here, the first question is not what failed but whether the part it needs is still being made. Replacement parts for systems that have been in circulation since before the housing market turned are sometimes available and sometimes not, and that gap is what drives the difference between a straightforward repair and a conversation about what comes next.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in the basement, utility room, or closet and is the piece a contractor goes to first. Inside it, the heat exchanger is the part that takes the most abuse over a season. A cracked exchanger or a failed ignitor are the reasons a furnace runs but produces no heat, or does not run at all.
The blower motor sits at the base of the furnace cabinet and moves conditioned air into the supply side of the house. The flue pipe runs from the top of the furnace to an exterior vent and carries combustion gases out. A contractor checks both, because a seized blower or a blocked flue can each stop the system cold.
The drawing shows the general layout of these components, and a licensed contractor determines which of them apply to your particular setup.
