Furnaces here have not been running against a punishing weather environment. 50 severe weather events were recorded in Kleberg County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event in this county, not a standing condition every system has been grinding through. When a contractor opens a furnace that has stopped working, worn heat exchangers, failed ignitors, and degraded burners point back to how old the equipment is and how well it has been maintained, not to weather-driven stress. The repair scope follows from that, and so does the honest diagnosis.
Older ductwork and ageing equipment share a house, but on a repair call what stops the job is usually neither. Half the homes in Kleberg County, Texas were built in 1976 or earlier (2020-2024 ACS 5-year). A furnace that has run in a house this old has cycled through enough heat seasons that the heat exchanger, the igniter, and the limit switches have worn in ways that are not always visible until the unit is open. When the opened system reveals a cracked heat exchanger or a control board on a discontinued platform, parts availability decides whether the repair is even possible, and that answer takes research, not guesswork.
The Parts of a Furnace a Contractor Checks During Repair
The heat exchanger sits inside the main cabinet and is the piece a contractor looks at closely when a furnace runs but fails to heat properly or trips safety limits. The burner assembly sits just below it and is the first stop when the furnace won't ignite or fires unevenly. The blower motor, housed at the base of the cabinet, moves conditioned air out; when it fails, heat builds and the system shuts itself down.
The flue pipe runs from the cabinet up and out of the house, carrying combustion gases away, and a crack or blockage there can trip safety switches before any other part shows trouble. The control board sits inside the cabinet and coordinates every component; a contractor reads its fault codes early in a repair call because those codes often point straight to the failing part.
The drawing shows the general layout of a furnace system, and a licensed contractor determines which parts apply and what condition they are in for your specific home.
