A contractor quoting a furnace repair in Armstrong County has to decide what actually wore the system down. 162 severe weather events were recorded in Armstrong County, Texas between 2015 and 2024. At roughly that rate, severe weather is an occasional pressure on equipment here, present but not relentless. That distinction changes what a contractor prices first: heat exchangers, igniters, and control boards that age out on their own schedule rather than components stressed by repeated extreme-load cycles. A system that has been running without regular service will show the same wear patterns here regardless of what the sky has done.
Ductwork and wiring in a house this old were sized and run for equipment that no longer exists. Half the homes in Armstrong County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). A furnace installed in a house like that is already a replacement, possibly more than once over, and each cycle narrows the parts pool. When a contractor opens a failed unit, what decides the repair is whether the manufacturer still makes what the system takes. If the part is discontinued, the job changes shape entirely.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits inside the furnace cabinet, usually in a utility closet, basement, or garage, and it is where combustion heat passes into the air your home circulates. When a furnace blows cold, runs in short bursts, or trips a limit switch repeatedly, the heat exchanger and the burners directly below it are where a contractor looks first.
The blower motor and its fan wheel sit at the base of the cabinet and push conditioned air out through the supply plenum. The draft inducer, the igniter, the flame sensor, and the gas valve all cluster around the burner assembly, and each one can stop a furnace from lighting or keeping a flame.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply to the specific system in your home.
