Getting the load calculation right before the furnace goes in is the decision that shapes everything that follows. Homes in Mercer County, ND run heat about nine months a year, from September through May. The burner and heat exchanger cycle through that entire span, accumulating wear on every start and stop, and a unit that was sized short has no slack to absorb it. A contractor who quotes accurately for this county is working out what the equipment will be asked to carry for most of its life, not just for a mild week in October. Undersizing shows early here because the idle season is short and the equipment has little time to recover.
Ductwork laid in for an older furnace carries assumptions about airflow, trunk sizing, and return placement that a different system does not share. Half the homes in Mercer County, North Dakota were built in 1981 or earlier (2020-2024 ACS 5-year). A contractor quoting a new furnace here often finds that the distribution side of the job takes more decision-making than the equipment selection does, because the existing runs were built around whatever was heating the house when it went up. Whether the ductwork can carry the new system without rerouting or resizing is the question that shapes the scope and the price.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or closet, and it is the unit a homeowner sees first when they walk into that space. Inside it, a heat exchanger warms the air that moves through the house, and a blower fan pushes that air into the supply ducts. The burner assembly and gas valve sit within the cabinet as well.
The flue pipe runs from the furnace up and out of the house, carrying combustion exhaust away. Alongside the furnace, a contractor also installs the thermostat on an interior wall, which is the control point for the whole system. A filter housing sits at the air return where air enters the unit before it reaches the heat exchanger.
The drawing shows a representative layout, and a licensed contractor determines what applies to the specific configuration of your house.
