A furnace breaking down in Comanche County is almost always a story about age or maintenance gaps, not about what the weather has put it through. 50 severe weather events were recorded in Comanche County, Texas between 2015 and 2024. At that rate, severe weather is something most equipment here encounters now and then, not a grinding condition that wears components ahead of schedule. A contractor diagnosing a failed heat exchanger or a cracked inducer in this area will look first at filter history, combustion records, and how long the unit has been in service. The weather record simply does not carry enough weight to explain most of what goes wrong here.
Ductwork and wiring in a house this old were put in for systems that no longer exist, adapted more than once, and carry a repair history a contractor has to read before they can price anything. Half the homes in Comanche County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what a furnace manufacturer supports today is where repair jobs get complicated: a contractor who opens a furnace here may find that the heat exchanger, the igniter, or the control board it takes is discontinued or on a long lead time. The age of the housing sets the conditions; the age of the specific equipment inside it determines the parts question.
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 closet, and it is the piece that transfers heat from combustion into the air your home circulates. When it cracks or corrodes, exhaust gases can enter the living space, and a contractor will inspect it closely before anything else. The burner assembly sits just below it and is the first stop when a furnace fails to produce heat at all.
The blower motor and fan sit at the base of the cabinet and push conditioned air through the supply side of the system. The control board mounts inside the cabinet door and coordinates ignition, the blower, and the safety switches. When a furnace short-cycles, runs without heating, or refuses to start, the board and the igniter are the pieces a contractor reads for fault codes first.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what condition they are in for your specific system.
