A furnace repair quote in Conejos County starts with the ignition system and heat exchanger, because those are the components that carry the load here. Homes in Conejos County, CO run heat about eleven months a year, from August through June. Burner cycles add up across that kind of season, and the igniter, flame sensor, and heat exchanger each degrade in ways that compound each other. A contractor who pulls a cracked heat exchanger on what looked like a simple ignition call is not finding a surprise; they are finding what the workload produced. Pricing the visible fault without checking those components leaves the next failure undiagnosed.

Ductwork in these houses was put in for furnaces that no longer exist. Half the homes in Conejos County, Colorado were built in 1982 or earlier (2020-2024 ACS 5-year). When a contractor opens a furnace here, the question is less often what is wrong and more often whether the part it needs is still manufactured. A heat exchanger crack or a failed inducer motor on a unit this old sends the search to specialty suppliers, and sometimes the search ends with a replacement recommendation rather than a repair. That is the variable the age of the housing actually controls.
The Parts of a Furnace a Contractor Checks First

The heat exchanger sits inside the furnace cabinet and is the first place a contractor looks when a furnace is producing little or no heat. Cracks in the exchanger are a safety concern, not just a performance one. The burner assembly sits just below it, and when ignition is unreliable or the flame pattern is wrong, that is where the diagnosis starts.
The blower motor and its fan wheel sit at the base of the cabinet and push conditioned air into the supply side of the system. A failed motor means no airflow even when the burner is working fine. The inducer motor, the pressure switches, and the control board each govern whether the furnace starts and runs through a full cycle, so a contractor checks their signals when the unit short-cycles or fails to light.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply to your specific equipment and installation.
