A contractor diagnosing a furnace in Crane County starts by ruling out what the record here does not strongly support. 34 severe weather events were recorded in Crane County, Texas between 2015 and 2024. At that rate, severe weather lands here often enough to notice but not often enough to account for most of what goes wrong inside a furnace. Worn heat exchangers, cracked igniters, and failing blower motors point back to age and how well the system was installed and maintained. The weather is a background variable in this county, and a good diagnosis treats it that way.
Ductwork and wiring in a house get replaced on different schedules than the furnace sitting inside it, which means the furnace a contractor opens in Crane County can belong to any era the house has passed through. Half the homes in Crane County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). A furnace that has spent years running in that stock may take a heat exchanger or a control board that the original manufacturer no longer produces, and that parts availability question is what shapes the repair estimate more than the labor does. A contractor who finds a discontinued component has to decide between sourcing aftermarket parts and telling the homeowner what the alternative costs.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits inside the furnace cabinet and is where a contractor looks when the system runs but does not heat, or when combustion smells reach the living space. The burners sit just below it and are the first stop when ignition fails or the flame behaves unevenly. The draft inducer motor, mounted at the top of the cabinet, pulls combustion gases out and is a common source of unusual noise on startup.
The blower motor sits at the base of the cabinet and pushes conditioned air into the supply ducts. When airflow drops or rooms heat unevenly, that is where a contractor looks. The control board and the ignitor both sit inside the cabinet as well, and either one can produce a no-heat call that looks identical from the thermostat.
The drawing shows the general layout of a furnace system, and a licensed contractor determines what applies to your particular installation.

Severe Weather Events in Crane County
Extreme weather puts real strain on furnaces, forcing them to run harder and longer than they were sized for under normal conditions. How much of that load a furnace carries depends on what the local climate actually delivers, and Crane County has its own record.
