A contractor sizing or installing a furnace in Larue County starts with what the house actually demands, not a catalog default. 64 severe weather events were recorded in Larue County, Kentucky between 2015 and 2024. At that rate, severe weather is a real but infrequent presence, not the kind of relentless load that grinds heat exchangers and pressure switches down season after season. A system failing here is more likely failing because it was undersized at installation, poorly sealed on the flue, or left to run without service than because the county's weather wore it out. That is what a contractor has to establish before they can spec the right replacement unit.
Ductwork sized and routed for older heating equipment shapes every furnace installation job in this county. Half the homes in Larue County, Kentucky were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor putting in a new furnace has to assess whether the existing trunk lines and branch runs will move air the way the new unit demands, or whether they will starve it. The electrical side follows the same logic: panels from that era were not wired for the loads current equipment draws, and a contractor finds out early whether the service needs attention before the furnace goes in.
What Gets Installed With a New Furnace
The furnace itself sits in a mechanical room, basement, or utility closet and is the heart of what a contractor brings in. A burner assembly inside it generates heat, and a heat exchanger transfers that heat to the air moving through the system. The blower motor, housed in the same cabinet, pushes that warmed air out toward the rest of the house.
The flue pipe runs from the furnace up and out of the house, carrying combustion gases away from the living space. A new thermostat goes on an interior wall and gives the homeowner control over when the furnace fires and at what target temperature. The contractor also fits a new air filter housing at the return-air opening of the furnace cabinet.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific configuration of your house.
