Takes about a minute. No obligation.
Ductwork sized and routed for the original heating equipment is what a contractor finds in much of this borough's housing. Half the homes in North Slope Borough, Alaska were built in 1984 or earlier (2020-2024 ACS 5-year). That matters for furnace installation because the existing runs may not carry the airflow a new unit requires, and the gaps or bends that were acceptable for an older system become problems when a different one is pushing air through them. What the contractor opens up in the walls and crawlspaces sets the actual scope of the job.
What Gets Installed With a New Furnace
The furnace itself sits in a utility space, basement, or closet at the center of the house. It holds the heat exchanger and the burner assembly, which produce the heat, and the blower motor, which pushes conditioned air out into the living areas. This is the unit a homeowner sees when they open that mechanical room door.
The flue pipe runs from the furnace to an exterior wall or roof, carrying combustion gases out of the house. Alongside it, the contractor installs the air handler components and connects the system to the thermostat on the wall, which is the one piece in the home's living space that a homeowner touches every day.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
