Sizing a furnace for a Franklin County home is a load calculation before anything else. Homes in Franklin County, NE run heat about eight months a year, from October through May. The burner and heat exchanger cycle through that entire stretch every year, and a unit that is undersized for the actual heat loss in the house runs longer each cycle to compensate, which accelerates wear on the ignition system and the heat exchanger itself. A contractor quoting a replacement here needs to know the thermal envelope of the house before settling on equipment, because a furnace that would coast through a short season will show fatigue far sooner in one this long.
Ductwork that was sized and routed for an earlier generation of equipment shapes every furnace installation in this county before the new unit is even uncrated. Half the homes in Franklin County, Nebraska were built in 1940 or earlier (2020-2024 ACS 5-year). When the air distribution in a house was designed around something fundamentally different from what runs now, a contractor has to determine whether existing trunks and branch runs can actually move air the way a modern furnace needs them to, or whether the supply side becomes the job. The electrical picture matters too, but ductwork is where the constraint typically sits in stock this old.
What Gets Installed With a New Furnace
The furnace itself sits in a mechanical room, basement, or utility closet and is the core unit a contractor places first. Attached to it is the flue or exhaust vent, which runs to an exterior wall or roofline to carry combustion gases out of the house. The gas supply line connects to the burner assembly inside the cabinet.
The air handler components built into the furnace cabinet include the blower, the heat exchanger, and the filter housing, all of which sit within that same cabinet and connect directly to the supply and return duct openings. A thermostat mounts on an interior wall and serves as the control point for the whole system.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one applies to your house.
