Sizing a furnace for Livingston County takes more than picking a unit off a spec sheet. 79 severe weather events were recorded in Livingston County, Kentucky between 2015 and 2024. At that rate, severe weather is a recurring fact of life here, not a freak occurrence, which means a contractor setting up a new furnace has to account for what the system will be asked to carry across a range of conditions. Ductwork routing, equipment placement, and load calculations all get shaped by a climate that pushes a system hard on a regular basis.
Ductwork laid out for an older heating system carries assumptions about airflow, return placement, and trunk sizing that a new furnace may not share. Half the homes in Livingston County, Kentucky were built in 1978 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a furnace here is also reading whether the existing distribution system can carry what the new unit will push through it. Where it cannot, the ductwork gets modified before the equipment question is fully settled. The electrical side follows the same logic: the service a house was wired with was sized for what the house originally ran, and a new furnace draw gets checked against that before anything is ordered.
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 box that produces the heat. A flue or exhaust vent runs from the furnace to an outside wall or through the roof, carrying combustion gases out of the living space.
The air handler and blower sit within or directly beside the furnace cabinet and push conditioned air into the supply side of the duct system. A thermostat mounts on an interior wall and serves as the control point, telling the furnace when to fire and when to shut off.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your house and how each one is positioned.

Severe Weather Events in Livingston County
Weather puts a load on heating equipment, and that load is shaped by local conditions. A furnace sized and installed for what Livingston County actually sees will run differently than one spec'd from a generic chart.
