Homes in Lowndes County, MS run heat about five months a year, from November through March. Each cycle of that burner and heat exchanger adds stress to the ignition system and the heat exchanger itself, and a season that runs from November through March leaves little idle time for minor faults to sit unnoticed. By spring, a furnace that has been short-cycling, running dirty, or losing flame signal has already logged the hours that show up in cracked exchangers and worn igniters. A contractor diagnosing a repair here starts with those components first.
Ductwork in a house accumulates decades of exactly what ran through it: rust at the joints, collapsed flex runs, and heat-exchanger debris that shifts the moment a technician opens the cabinet. Half the homes in Lowndes County, Mississippi were built in 1981 or earlier (2020-2024 ACS 5-year). A furnace of that vintage draws on a parts catalog that has been shrinking since it left the factory, so a repair that starts as a failed inducer motor or a cracked heat exchanger can stall at sourcing rather than at the repair itself. The contractor prices the job once they know what the opened unit actually holds and what is still available to put back in it.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet, in the utility room or basement, and it is the part that actually warms the air your blower pushes through the house. Cracks or corrosion here are a serious fault. The burner assembly feeds it flame, and a contractor will pull and inspect both early in any repair call.
The blower motor and its wheel sit just below or beside the heat exchanger and move conditioned air into the supply plenum. The igniter, flame sensor, and inducer motor are smaller components mounted in and around the burner compartment. Each has a distinct failure pattern, and a contractor traces the symptom back to whichever piece has stopped doing its job.
The drawing shows a typical furnace layout, and a licensed contractor determines what applies to the specific equipment and configuration in your home.
