A furnace installation in Metcalfe County starts with what the house actually demands, not with a weather record that dominates the decision. 53 severe weather events were recorded in Metcalfe County, Kentucky between 2015 and 2024. At that rate, severe weather is something the equipment encounters now and then, and a contractor pricing and sizing a furnace here is focused on the building envelope, duct layout, and installation quality rather than on a climate that routinely hammers equipment. Get the sizing and the install right and the furnace handles what this county sends.
Ductwork laid down for an older furnace carries assumptions about airflow, trunk sizing, and return placement that a new unit will expose fast. Half the homes in Metcalfe County, Kentucky were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor quoting a furnace here has to trace what is in the walls and ceiling before the equipment selection means much, because a duct system configured for a different generation of heating can restrict or unbalance a new furnace regardless of how well the unit itself is spec'd. Electrical service is the second check. A new furnace's control board and blower draw differently than what the original circuits were run for.
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, pulling air across a heat exchanger and pushing warm air into the supply side of the duct system. The blower motor inside the cabinet drives that airflow.
The flue pipe runs from the furnace up and out of the house, carrying combustion gases away from the living space. The thermostat mounts on an interior wall and serves as the control point, telling the furnace when to fire and when to shut off. Some installations also include a separate air handler or coil cabinet when the furnace is paired with a cooling system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Severe Weather Events in Metcalfe County
