A contractor quoting a furnace install in Gilmer County starts with the structure of the house, not the weather history, because the climate here puts modest demands on heating equipment. 66 severe weather events were recorded in Gilmer County, West Virginia between 2015 and 2024. At that rate, severe weather is something a system might see a handful of times across its life, which means the installation decisions that matter are how the unit is sized for the home's heat loss and how tightly the work is done. A poorly sized furnace in a house like this runs short cycles, wears its heat exchanger unevenly, and underheats rooms at the far end of the duct run.
Ductwork laid in for an earlier era of heating does not automatically carry a modern furnace well. Trunk sizes, branch layouts, and return configurations were sized for equipment with different static pressure requirements, and finding out whether what is in the walls will work means measuring, not assuming. Half the homes in Gilmer County, West Virginia were built in 1974 or earlier (2020-2024 ACS 5-year). A contractor quoting a furnace installation here has to treat the existing duct system as an open question from the start, because a unit that is correctly sized for the house can still underperform if the distribution network behind the walls restricts it.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or closet and is the unit that generates heat. A contractor installs the heat exchanger inside it, which is the metal chamber where combustion happens, and the blower motor beside it, which pushes conditioned air out into the house.
The flue pipe runs from the furnace up and out through the roof or an exterior wall, carrying exhaust gases out of the living space. The thermostat mounts on an interior wall and is the control point that tells the furnace when to fire and when to stop.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your home and its existing setup.
