Sizing a furnace correctly for this house is the decision a contractor has to settle before anything else, because the burner and heat exchanger will be cycling for most of the calendar year. Homes in Labette County, KS run heat about seven months a year, from October through April. A unit that is undersized runs longer cycles to chase the thermostat, which loads the heat exchanger more than it was rated for and shortens the ignition system's service life. A contractor quoting a replacement here has to do a proper load calculation for this house, this insulation, this ductwork, not pull a number from the old unit's nameplate.
Ductwork laid for a mid-century furnace carries assumptions about airflow that a modern unit will not share. Half the homes in Labette County, Kansas were built in 1958 or earlier (2020-2024 ACS 5-year). That gap is what a contractor has to resolve before a new furnace can be matched and priced: whether the existing trunk lines move enough air for the equipment being quoted, and whether the electrical service at the panel can carry the load. A house may sit on its original duct layout, or it may have been rerouted once or more since. The contractor opens those questions before the unit itself is chosen.
What Gets Installed With a New Furnace
The furnace itself sits inside the house, most often in a basement, utility closet, or mechanical room. It is the cabinet that produces heat, and it is the largest piece going in. Attached to it, the flue pipe runs from the unit to an exterior wall or up through the roof, carrying combustion gases out of the house.
The air handler components built into or paired with the furnace include the blower and the filter housing, both of which sit within the same cabinet or directly adjacent to it. The thermostat mounts on an interior wall and gives the homeowner control over when and how the system runs. A new furnace also comes with a gas valve and ignition assembly, both seated inside the cabinet.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific home.
