A furnace repair call here starts with the burner assembly and ignition system, because those are the parts doing the actual work every heating season. Homes in St. Francis County, AR run heat about five months a year, from November through March. That kind of cycling wears igniters, degrades flame sensors, and stresses heat exchanger seams in ways that show up as hard failures rather than gradual performance loss. A contractor quoting a repair in this county runs down those components first, because they account for most of what breaks.
Furnace repairs in housing stock this old tend to turn up components that have outlasted the original equipment by a wide margin. Half the homes in St. Francis County, Arkansas were built in 1980 or earlier (2020-2024 ACS 5-year). A house built by that point was set up for a furnace that a contractor today will not recognize from the parts shelf, and the ignition assemblies, heat exchangers, and flue connections inside what runs now are often the third or fourth iteration of whatever filled that space. When a contractor opens the unit, the condition of those parts tells more about the repair scope than anything visible from the outside.
The Parts of a Furnace a Contractor Checks First
The furnace cabinet is the piece most homeowners recognize, sitting in a basement, utility closet, or crawlspace. Inside it, the heat exchanger and burner assembly do the core work. When a furnace runs poorly or not at all, the burner, the heat exchanger, and the igniter are where a contractor looks first.
The blower motor pushes conditioned air out of the cabinet and into the duct system, and the flue or exhaust vent carries combustion gases out of the house. The thermostat sits on a wall elsewhere in the home and tells the furnace when to fire. A fault in any of these, including a failing motor or a cracked flue connection, shows up as lost heat, odd cycling, or poor airflow.
The drawing shows a representative layout, and a licensed contractor determines what applies to your specific system and home.
