Tell us about the job
Takes about a minute. No obligation.
A furnace in this county has been running against one of the more active severe weather records in the state. 148 severe weather events were recorded in Hidalgo County, Texas between 2015 and 2024. That load lands on heat exchangers, pressure switches, and ignition controls over years, and a contractor doing repair work here checks those components for weather-driven wear before drawing any conclusion about age or neglect. A cracked heat exchanger in a house that has seen this kind of weather record is a different diagnostic finding than the same crack in a system that sat through quiet seasons.
Ductwork and framing tell you when the house went up; they say nothing about when the furnace inside it was last replaced. Half the homes in Hidalgo County, Texas were built in 2000 or earlier (2020-2024 ACS 5-year). A furnace swapped in years after a house was built draws from a different parts catalog than one original to that construction, and a repair tech has to confirm which generation of components the system actually takes before pricing the job. If a heat exchanger or control board is no longer manufactured, the repair scope shifts. That determination comes from opening the unit, not from the permit date on the wall.
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 is the surface across which the burner's heat passes before warm air moves into your home. Cracks or corrosion here are a serious finding. The burner assembly and igniter sit just below it, and a fault in either one is often why a furnace runs briefly and then shuts off, or will not start at all.
The blower motor and its fan wheel sit at the bottom of the cabinet and push conditioned air out through the supply plenum. The flue pipe runs from the cabinet up and out of the house, and a contractor checks it for blockages or separation. The control board ties the whole system together, and when a furnace behaves erratically, that board is one of the first places a contractor looks.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply to your specific setup.
