A contractor quoting a furnace install in Oldham County starts with the structure: ceiling height, insulation, duct layout, and how the house actually holds heat on a cold night. 98 severe weather events were recorded in Oldham County, Kentucky between 2015 and 2024. At roughly the midpoint of counties nationwide, that record means severe weather here is real but not the dominant variable shaping an install. What drives sizing decisions is the building, not an outsized local climate. A contractor who skips a proper load calculation here will oversize or undersize the furnace for reasons that have nothing to do with storms.
Ductwork laid in for older furnaces carries assumptions about airflow, return placement, and trunk sizing that a new unit may not match. Half the homes in Oldham County, Kentucky were built in 1994 or earlier (2020-2024 ACS 5-year). That means a contractor evaluating a furnace installation here spends real time on what is already in the walls before the equipment question is settled. If the existing duct layout cannot move the volume a modern furnace delivers, the install scope grows. The electrical side is usually the simpler check. The ductwork is where the answer actually lives.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a basement, utility room, or closet. It is the central unit that generates heat by burning fuel or running electrical elements through a heat exchanger, then pushing that warmed air into the living space. A flue pipe runs from the unit to an exterior vent, carrying combustion gases out of the home.
The air handler and blower fan work alongside the furnace, moving conditioned air through the supply side of the system and drawing return air back in. A thermostat mounts on an interior wall and serves as the control point, telling the furnace when to fire and when to stop. The contractor also sets the condensate or venting connections that tie the unit to the outside.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your house and its existing setup.
