A furnace repair call in Catron County starts with the ignition system and the heat exchanger, because those are the parts that cycle hardest and longest. Homes in Catron County, NM run heat about nine months a year, from September through May. The burner fires and shuts down repeatedly across that stretch, and the igniter takes the punishment every time. Hairline cracks in the heat exchanger and a degraded igniter are what a contractor opens the cabinet expecting to find, not as a guess but as a reading of how the equipment has been worked.

Ductwork in a house this old was run for whatever heated it first, and the furnace sitting in it now is not necessarily what that ductwork was sized for. Half the homes in Catron County, New Mexico were built in 1986 or earlier (2020-2024 ACS 5-year). When a contractor opens a furnace in stock like this, the question is whether the parts it takes are still being made or have to be sourced, and that answer changes the scope and the timeline of the repair more than the fault itself does.
The Parts of a Furnace a Contractor Checks First

The furnace itself sits in a utility room, basement, or closet and is the piece a contractor goes to first. Inside it, the heat exchanger is the part most worth attention on a repair call: cracks there let combustion gases into the living space, and a failed blower motor means warm air never leaves the cabinet at all.
The flue pipe runs from the furnace to the outside and carries combustion exhaust out of the house. The thermostat, mounted on a wall in the living area, is the control point that tells the furnace when to fire, and a fault there can look exactly like a furnace problem until the contractor rules it out.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and home.
