Sizing a furnace for Greenwood County requires a contractor to account for a long, unbroken demand on the burner, the heat exchanger, and the ignition system. Homes in Greenwood County, KS run heat about seven months a year, from October through April. A system that is undersized, or whose combustion air supply was set up carelessly, cycles harder and more often through that stretch, and the heat exchanger is the first component to carry that cost. A contractor quoting a new furnace here works out the load calculation before settling on equipment, because an undersized box will not hide the gap for long.
Ductwork sized for a furnace that has long since been replaced does not automatically fit the next one. Half the homes in Greenwood County, Kansas were built in 1956 or earlier (2020-2024 ACS 5-year). What a contractor installing a new furnace finds behind the walls and in the ceiling runs is whether those ducts move enough air, whether the runs are sealed, and whether the electrical service the new unit draws from was ever sized for it. Those answers come from the house, and they shape the quote before the equipment choice does.
What Gets Installed With a New Furnace
The furnace itself sits in a mechanical room, basement, or utility closet and is the heart of the purchase. A heat exchanger inside it warms the air that moves through your home. Attached to the unit, the blower motor pushes that warmed air out into the supply side of your duct system.
The flue pipe runs from the furnace to an exterior wall or up through the roof, carrying combustion gases out of the house. Alongside it, a new thermostat mounts on an interior wall and serves as the control point for the whole system. A contractor also installs or replaces the filter housing where the return air re-enters the unit.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.
