Sizing a furnace for a Wood County home requires a contractor to treat severe weather as part of the baseline, not as something a system might occasionally face. 121 severe weather events were recorded in Wood County, Texas between 2015 and 2024. At that rate, a contractor cannot pull a capacity figure from a catalog and call it done. The local load shapes what equipment gets specified, how the ducts get laid out, and how tightly the install gets executed, because a loose or undersized setup will be stressed by conditions that arrive regularly here.
Ductwork laid for an older furnace generation carries assumptions about airflow, sizing, and routing that a new unit may not share. Half the homes in Wood County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor installing a furnace in a house from that era of the stock has to assess whether the existing duct runs will move air the way the new equipment needs, or whether sections have to be modified before the system will perform correctly. The electrical side matters too, since panel capacity for heating loads has shifted with the equipment. What the house already contains sets the scope before the unit is ever ordered.
What Gets Installed With a New Furnace
The furnace itself sits in a utility room, basement, or closet and is the unit that produces heat for the house. Attached to it is the air handler, which pulls air across the heat exchanger and pushes it into the supply side of the system. Together these two pieces are what a homeowner is buying when they buy a new furnace installation.
The flue pipe runs from the furnace through the wall or roof and carries combustion exhaust out of the house. Alongside it, the thermostat mounts on an interior wall and serves as the control point that tells the furnace when to fire and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

Severe Weather History in Wood County
