Takes about a minute. No obligation.
A furnace in Orleans Parish puts nearly all of its work into a short stretch of the calendar, and the burner, heat exchanger, and ignition system absorb that load in a concentrated run. Homes in Orleans Parish, LA run heat about five months a year, from November through March. The igniter and flame sensor cycle with every call for heat, and a contractor diagnosing a repair here checks those parts first because they accumulate failure faster than components that run year-round at lower intensity. When the system sits idle through the warm months, a cracked heat exchanger or a weakened igniter stays hidden until the first cold night, which is the worst time to find it.
Furnace repair in a house this old often stalls not at the diagnosis but at the parts. Half the homes in Orleans Parish, Louisiana were built in 1960 or earlier (2020-2024 ACS 5-year). A heat exchanger or burner assembly pulled from a furnace running in stock like this may take a part that has been discontinued, substituted, or sourced only through specialty suppliers. A contractor opening the unit has to confirm what generation of components is actually inside before a repair scope means anything, because what was originally installed and what is running now are frequently different things.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet in your utility space, basement, or closet, and it is where combustion heat passes into the air your home breathes. When it cracks or warps, the furnace often short-cycles or throws a fault code. The burner assembly feeds it directly, and a contractor looks there when ignition is weak or the flame is unsteady.
The blower motor sits below the heat exchanger and pushes conditioned air out through the supply plenum into the rest of the house. The inducer motor, draft pressure switch, and limit switches all sit within or just above the cabinet, each one signaling the furnace to run or shut down. A failed limit switch or a stuck inducer are among the first things a contractor traces when the furnace runs briefly and then stops.
The drawing shows a general furnace layout, and a licensed contractor determines which components apply to the specific unit and configuration in your home.
