A contractor diagnosing a furnace repair in Terry County starts by ruling out the mundane causes, because the weather here does not hand them an easy explanation. 55 severe weather events were recorded in Terry County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county, not a constant. A heat exchanger that has cracked, a blower motor that has seized, or a control board that has failed is far more likely carrying years of deferred maintenance or an aging install than any accumulated storm load. The contractor's first questions are about service history and how long the equipment has been running.
Ductwork and heat exchangers tell you more about a repair job than the thermostat reading does. Half the homes in Terry County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). A furnace that has been swapped once or twice in a house of that age can land on a generation of equipment where replacement parts are scarce or sourced only through specialty suppliers. When a contractor opens the unit, what decides the repair scope is whether the components inside are still in active production and what it takes to get them.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet and is the part a contractor looks at closely during any repair call. Cracks or stress in it let combustion gases into the airstream, so it is often where a diagnosis starts. The burner assembly sits just below it, feeding the flame that generates the heat.
The blower motor and fan sit in the lower half of the cabinet and push conditioned air out through the supply plenum into the house. The igniter, flame sensor, and control board are smaller components mounted inside the cabinet, but each one can bring the whole system down when it fails. The flue pipe runs from the top of the furnace up and out of the house, removing exhaust gases.
The drawing shows a general furnace layout, and a licensed contractor determines which components apply and what condition they are in for your specific system.
