Sizing a furnace for a house in Hancock County starts with the building itself: its insulation, its layout, its infiltration. 64 severe weather events were recorded in Hancock County, West Virginia between 2015 and 2024. At that rate, severe weather is a periodic reality, not a standing pressure that bends every installation decision. A contractor quoting a new furnace here is working out what this particular structure needs to stay warm through a West Virginia winter. Duct layout, equipment output, and commissioning quality are what determine whether that furnace performs year after year.
Ductwork laid down for an older heating system was sized and routed for that system, and a new furnace draws and distributes air differently. Half the homes in Hancock County, West Virginia were built in 1959 or earlier (2020-2024 ACS 5-year). A contractor installing a furnace in a house from that era has to assess what the existing duct network will actually carry before any equipment decision is final. If the runs are too narrow or the returns too few, the new unit will not perform to spec regardless of what is on the nameplate. The electrical side gets checked for the same reason. What the house already contains decides the scope of the job.
What Gets Installed With a New Furnace
The furnace itself sits in a mechanical room, basement, or utility closet and is the heart of the installation. A contractor sets the unit in place, connects it to the gas supply, and ties it into the existing duct opening. The heat exchanger and burner assembly live inside that cabinet.
The flue pipe runs from the furnace up through the house or out a sidewall, carrying combustion gases outside. Alongside it, the contractor installs or replaces the air handler components and connects the thermostat wiring that tells the furnace when to fire.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home's configuration.
