A furnace contractor quoting a job in Wichita County has to size and seal for what the climate actually delivers, not for what a catalog average assumes. 303 severe weather events were recorded in Wichita County, Texas between 2015 and 2024. At that rate of severe weather, an undersized unit runs harder than it was built to and loses efficiency before it should. A properly sized install with tight ductwork and correct airflow carries that load without being constantly on the edge of its limits. The equipment brand matters far less than whether the install was done to spec for this area.
Ductwork sized for an older heating system carries assumptions about airflow that a new furnace will test. Half the homes in Wichita County, Texas were built in 1972 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what runs in it now is where a furnace installation either goes smoothly or gets complicated. A contractor assessing the existing duct runs and the electrical service before committing to a unit is doing the work the building's age makes necessary.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a utility closet, basement, or garage, and it is the unit that produces heat by burning fuel or running electric resistance coils. The heat exchanger lives inside that cabinet, transferring warmth from the combustion side to the air that moves through your home. A new installation means both of these go in together as a matched assembly.
The flue pipe runs from the furnace to the outside of the house, carrying exhaust gases out safely, and its routing depends on where the furnace lands in the structure. The air handler or blower compartment, also inside the cabinet, pushes conditioned air out into the supply side of your home's duct system. The thermostat mounts on an interior wall and gives the whole system a control point.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.
