A furnace that stops working in Live Oak County has most likely been let down by its own components, not by what the weather here asked of it. 40 severe weather events were recorded in Live Oak County, Texas between 2015 and 2024. At that rate, severe weather lands infrequently enough that it rarely drives a repair call on its own. A contractor diagnosing a furnace here will check the heat exchanger for fatigue, the igniter for wear, and the filter for the kind of neglect that builds quietly over seasons. Weather is worth ruling out, but age and service history are where the answers tend to live.
Furnaces in a housing stock this old carry a repair history inside them. Half the homes in Live Oak County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). A unit that has run through that many Texas winters accumulates heat exchanger fatigue, burner scaling, and ignition wear that a contractor reads from the components themselves once the cabinet is open. The parts a system of that vintage takes are not always in ready supply, so a technician diagnosing the fault also has to confirm what is still manufactured before a repair scope can be settled.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet, and it is the piece a contractor looks at closely during a repair call. Cracks or corrosion there affect the whole system. The burner assembly sits just below it, where the flame forms, and a dirty or misfiring burner is one of the first suspects when a furnace runs poorly or not at all.
The blower motor and its wheel sit in the lower section of the cabinet and push conditioned air out through the supply side of the house. The igniter, the flame sensor, and the control board are smaller components, but any one of them can stop the furnace from starting or cause it to shut down mid-cycle. A contractor traces the fault through each of these before drawing a conclusion.
The drawing shows a general layout of a furnace system, and a licensed contractor determines which parts apply and what work is needed in your specific home.
