A contractor called out to diagnose a furnace problem in Buncombe County has to weigh how hard the local climate has actually pushed the equipment before landing on a cause. 88 severe weather events were recorded in Buncombe County, North Carolina between 2015 and 2024. That puts this county in roughly the middle ground: severe weather here is real but not relentless, which means a furnace that has stopped working is pointing toward age, a filter that went too long unchanged, or a component that simply wore out under ordinary use. Storm load is worth considering, but it rarely explains the failure on its own.
Furnaces in stock this old have often been replaced once already, which means the unit a contractor opens may be a generation or two behind current production. Half the homes in Buncombe County, North Carolina were built in 1991 or earlier (2020-2024 ACS 5-year). When a part fails in a system that old, the first question is whether it is still manufactured, and the answer determines whether the repair is a parts job or a full replacement conversation. Heat exchangers, draft inducers, and control boards for discontinued models run on whatever supply the secondary market still holds.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in a utility space, basement, or closet and is the piece a contractor goes to first. Inside it, the heat exchanger and burners are the parts most likely behind a heating failure. A cracked heat exchanger or a burner that won't fire will stop the system from producing any useful heat at all.
The blower motor moves conditioned air from the furnace into the supply side of the house and sits inside the furnace cabinet. Alongside it, the igniter and flame sensor work together to start and confirm combustion. When those components fail, the furnace may run its cycle without ever producing heat, or shut itself down before completing one.
The drawing shows a typical furnace layout, and a licensed contractor determines which components apply and what condition they are in for your specific system.
