A furnace installed in Randolph County is built to run against weather that comes around regularly, not occasionally. 105 severe weather events were recorded in Randolph County, West Virginia between 2015 and 2024. At that rate, severe weather is part of the normal load a system carries through its life here, which means a contractor sizing and speccing a furnace for this area is accounting for real and repeated demand. A unit undersized or poorly sealed at installation will feel that load in its first few winters. Getting the install right from the start is the work that determines how the equipment holds up.
Ductwork and electrical service sized for an older generation of equipment are what a contractor finds in much of this county's housing. Half the homes in Randolph County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). A new furnace draws differently and moves air at different pressures than what that ductwork was originally built around, so the existing system gets checked before anything is quoted or ordered. Whether the runs, the returns, and the panel can carry a new unit is what decides how the job actually goes.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or crawlspace and is the central unit a contractor installs. Inside it, the heat exchanger and burner assembly do the heating work, while the blower motor pushes conditioned air outward. The flue pipe runs from the unit up through the house to vent combustion gases outside.
The thermostat mounts on an interior wall and is the control point the homeowner uses every day. A contractor also installs or connects the air handler cabinet if the furnace shares a system with cooling equipment, and fits the supply and return air plenums where the furnace meets the duct openings.
The drawing shows a typical furnace layout, and a licensed contractor determines what the setup requires in your specific home.
