Furnaces in Comal County have been running against a consistent pattern of severe weather, and that load shows up in the parts that carry it hardest. 111 severe weather events were recorded in Comal County, Texas between 2015 and 2024. A contractor quoting a furnace repair here checks the heat exchanger, the ignitor, and the pressure switches first, because those are the components that accumulate stress from repeated weather-driven demand cycles. Age matters too, but the weather record here means a contractor cannot attribute a failure to age alone without opening the unit and ruling out stress-related wear on the working parts.
Furnaces in houses built around that median year are close enough to current production that the parts a repair calls for are still being made. Half the homes in Comal County, Texas were built in 2005 or earlier (2020-2024 ACS 5-year). A contractor opening a heat exchanger or a blower assembly here is not hunting down obsolete components or working around a discontinued control board. The housing stock is recent enough that the repair turns on what is actually wrong with the unit, and the bill follows from that.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits inside the furnace cabinet in the utility room or closet and is the part a contractor looks at closely during a repair call. Cracks or corrosion there affect the whole system. The burner assembly sits just below it and is where ignition problems, flame sensor failures, and gas valve faults tend to show up first.
The blower motor and its wheel sit at the base of the cabinet and push conditioned air out through the supply side of the house. The flue or exhaust vent runs from the top of the cabinet to the outside wall or roof, and a contractor checks it for blockages or separation that would cause the unit to shut down on a safety lockout.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply to the specific system and setup in your home.
