A furnace that stops working in Lexington city is probably not failing because of what the weather has put it through. 32 severe weather events were recorded in Lexington city, Virginia between 2015 and 2024. At that rate, severe weather is an event in a given year, not a constant pressure bearing down on every component. A contractor diagnosing a furnace here will look first at heat exchanger age, filter condition, and whether the original install was done to spec, because those are what actually wear a system out in a place where the weather rarely drives sustained load.
Furnace parts that have seen this many seasons of hard cycling do not always have a straightforward supply line behind them. Half the homes in Lexington city, Virginia were built in 1959 or earlier (2020-2024 ACS 5-year). A contractor opening a furnace in this city has real odds of finding a heat exchanger, burner assembly, or control board whose replacement part sits on a short or discontinued list, which changes what the repair costs and sometimes whether it is worth completing at the quoted scope.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in the basement, utility room, or crawlspace and is the piece a contractor goes to first. Inside it, the heat exchanger does the core work of warming the air, and a cracked or corroded exchanger is one of the more serious problems a technician looks for. The burners, which fire beneath the exchanger, and the igniter, which lights them, are frequent sources of a furnace that starts poorly or not at all.
The blower motor and its fan wheel sit inside the furnace cabinet and push conditioned air out through the house. The flue pipe runs from the top or back of the cabinet up and out of the building, carrying combustion gases away. A contractor checks the blower for wear and the flue for blockages or breaches, because either can cause the system to shut itself down.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.
