A furnace repair in this area starts with what the equipment has already been through. 187 severe weather events were recorded in Oldham County, Texas between 2015 and 2024. At that rate, severe weather is woven into normal operating life here, and a contractor working a furnace repair has to sort out how much of the wear in front of them reflects that load. Heat exchangers crack under pressure cycling. Ignition and limit controls fail earlier when a system is repeatedly pushed hard. The weather record shapes what a contractor looks at first, and what they find in those components usually tells them whether the repair is a straightforward fix or the sign of something that has been building for a while.

Ductwork and wiring that predate the current furnace by a generation are one thing; what the opened unit itself contains is what sets the repair scope. Half the homes in Oldham County, Texas were built in 1967 or earlier (2020-2024 ACS 5-year). A system installed into housing that old has run long enough for heat exchangers to pit, burner ports to clog with oxidized residue, and limit switches to drift from their original calibration. A contractor opening the cabinet here is not checking a young system. The parts question matters too: components from a furnace of this vintage sit at the edge of what distributors still stock, and a repair that starts as a single failed part can extend once the cabinet is open and adjacent wear becomes visible.
The Parts of a Furnace a Contractor Checks First

The heat exchanger sits inside the furnace cabinet in the utility room or closet and is the part a contractor looks at closely when something feels off. Cracks or stress in that metal are a common source of both heating failure and carbon monoxide risk. The burner assembly mounts just below it and is where the flame originates.
The blower motor and its fan wheel sit at the base of the cabinet and push conditioned air out into the house. The limit switch, the igniter, and the flame sensor are smaller components mounted nearby, and each one controls whether the burner fires and stays lit. A failed igniter or a fouled flame sensor accounts for a large share of furnaces that simply refuse to start.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply to your specific equipment and setup.
