A furnace contractor working a repair call in Montgomery County has to figure out what actually broke the equipment, and in most cases the weather is not the answer. 63 severe weather events were recorded in Montgomery County, Indiana between 2015 and 2024. At roughly that rate, severe weather is an occasional event here, not a standing condition, so a heat exchanger that cracked or a blower motor that seized is far more likely to point back to the age of the equipment or how well it was serviced over the years. A contractor who rules out weather load first can spend the diagnostic time where it belongs: on worn components, failing controls, and installations that were never quite right.

Basement or crawl space with concrete block walls and a bare wood joist ceiling, where insulated metal ductwork runs overhead, and a coiled flexible duct and two cardboard boxes sit on the concrete floor.

Older ductwork and older furnaces share a house, but they were not always installed at the same time, and what a contractor finds once the furnace is open often has little to do with when the walls went up. Half the homes in Montgomery County, Indiana were built in 1967 or earlier (2020-2024 ACS 5-year). A house that old has seen more than one heating system come and go, which means the furnace a contractor opens today was likely fitted into a space that was never designed around it. That matters for repair work because the parts a unit of this vintage takes are sometimes still made and sometimes are not, and the contractor has to confirm which before the job can be priced.

The Parts of a Furnace a Contractor Checks First

The heat exchanger sits at the core of the furnace cabinet, and it is the piece a contractor moves toward when the system is running but the house is not warming. The burner assembly feeds it directly. If combustion is off, that sequence is where the problem lives.

The blower motor sits below the heat exchanger and pushes conditioned air into the ducts. Alongside it, the control board reads signals from the thermostat and tells every other component when to act. A failed board can look like a dozen different problems, so contractors check it alongside the igniter and the flame sensor, which together handle the moment combustion starts.

The drawing shows a general cutaway of a furnace system, and a licensed contractor determines which components apply and what condition they are in for your specific installation.
