A furnace repair call in Pulaski County starts with what the system has been through, not what the season looked like. 69 severe weather events were recorded in Pulaski County, Illinois between 2015 and 2024. At that rate, severe weather is a periodic fact of life here, not a constant one, so a cracked heat exchanger or a failed inducer motor is more likely to trace back to the age of the unit or how consistently it was serviced than to weather load alone. A contractor will check both, but deferred maintenance is where most answers sit.
Furnaces in houses this old have typically outlasted at least one generation of parts. Half the homes in Pulaski County, Illinois were built in 1969 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit in stock like this, the question that decides the repair scope is whether the components that system takes are still manufactured or whether the job becomes a hunt through specialty suppliers. A heat exchanger, a draft inducer, a control board from a discontinued product line can turn a straightforward call into a longer one, and that is what the repair quote has to account for before anything else is priced.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in a basement, utility closet, or mechanical room and is the piece a contractor goes to first. Inside it, the heat exchanger is the part most worth understanding: cracks or failures there are what stop a furnace from being safe to run. The burners, which fire inside the heat exchanger, and the igniter, which lights them, are the other components a contractor examines early when a furnace stops heating or won't start.
The blower motor and its fan wheel sit at the base of the furnace cabinet and push conditioned air into the duct system. The flue pipe runs from the furnace up and out of the house, carrying combustion gases away. The control board ties all of it together, reading signals from the thermostat and telling each component when to act.
The drawing shows a typical furnace layout, and a licensed contractor will assess exactly which components apply to the specific system and conditions in your home.

Severe Weather Events in Pulaski County
Hard weather puts real stress on furnaces, cycling them through demand spikes, power fluctuations, and extended run times that wear components faster than steady-season use does. That wear is local, tied to what this area's weather actually delivers, which is why the record below is relevant to repair work here.
