Sizing a furnace here is a local question, not a catalog lookup by square footage. 93 severe weather events were recorded in Kenton County, Kentucky between 2015 and 2024. That puts severe weather squarely in the picture when a contractor works out what a system needs to carry over its life. Still, weather at that rate does not relieve the installer of getting the load calculation right, choosing equipment matched to the structure, and sealing the distribution correctly. Those decisions set whether the furnace holds up. The weather sets the conditions it holds up against.
Ductwork sized and routed for the equipment of an earlier era carries real friction into a furnace installation today. Half the homes in Kenton County, Kentucky were built in 1974 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what a contractor is now asked to put in it means the existing duct layout gets evaluated before anything else is quoted. If the runs are too narrow, too leaky, or routed in ways that choke airflow to a modern furnace, the installation scope grows before a unit is ever selected. Electrical service gets the same look.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or crawlspace and is the core unit a contractor puts in place. Attached to it is the heat exchanger, which sits inside the cabinet and is where combustion heat passes into the air that circulates through the house. The burner assembly mounts inside that same cabinet and is what a contractor connects to the gas supply.
The flue pipe runs from the furnace cabinet up and out of the house, carrying combustion gases away from the living space. The blower motor sits at the base of the cabinet and pushes conditioned air out into the supply side of the system. The thermostat mounts on a wall inside the house and is the control point a contractor wires into the new unit.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to this house based on what they find on site.

Severe Weather History in Kenton County
Heating equipment in this part of Kentucky works against whatever the climate throws at it, and that workload shapes how a system should be sized and installed. A furnace built for mild winters is not the same investment as one built for a county that sees real weather stress.
