Takes about a minute. No obligation.
A contractor quoting furnace repair in Washoe County starts with the components that cycle every time the burner fires: the ignition system, the heat exchanger, and the flame sensor. Homes in Washoe County, NV run heat about eight months a year, from October through May. That runtime accumulates on parts with tight tolerances, and cracks or fouling that might go unnoticed in a shorter season show up here as recurring faults rather than one-off failures. A homeowner calling for a repair late in the heating season is often looking at a part that has been degrading since October.
Furnace repairs in housing this old frequently stall at the parts stage. Half the homes in Washoe County, Nevada were built in 1991 or earlier (2020-2024 ACS 5-year). A system installed or retrofitted into a house of that era may run on components that manufacturers have discontinued or moved to specialty-order status, and a contractor opening a heat exchanger or cracked burner assembly here has to determine what is actually available before a repair scope can be set. That search, not the labor, is what determines how long a job takes and what it costs.
The Parts of a Furnace a Contractor Checks First
The heat exchanger sits at the core of the furnace cabinet and is the first place a contractor looks when a furnace runs but the house stays cold or when anyone smells something off. The burners feed it, and the blower motor pulls air across it and pushes that air into the supply plenum above. A failed igniter, a cracked exchanger, or a seized blower motor each produces a distinct set of symptoms that points a contractor toward that piece before anything else.
The flue pipe runs from the top of the cabinet up through the structure and carries combustion gases out of the house. The control board sits inside the cabinet and coordinates every other component, and a fault code on that board often tells a contractor which part failed before they remove a single panel. The gas valve and the pressure switches are smaller components, but either one going out can shut the whole system down.
The drawing shows a typical furnace layout, and a licensed contractor determines exactly which components apply to the system in your home.
