A contractor quoting a furnace installation in Richland County has to work out the full demand before settling on equipment size, because the burner, heat exchanger, and ignition system carry a workload that leaves little slack for an undersized or sloppily installed unit. Homes in Richland County, MT run heat about nine months a year, from September through May. The ignition system alone cycles through months of daily starts, and a heat exchanger running under strain that long develops fatigue that a looser climate would not produce as quickly. Sizing has to be right from day one here.

Existing ductwork is what a furnace installation in Richland County turns on. Half the homes in Richland County, Montana were built in 1980 or earlier (2020-2024 ACS 5-year). Ducts laid out for older equipment were sized and routed around what was running at the time, and a new furnace draws and distributes air differently enough that what is in the walls either fits the new unit or it does not. A contractor has to assess that before the equipment order is placed, not after.

What Gets Installed With a New Furnace

The furnace itself sits in a utility space, basement, or mechanical room and is the central piece of the installation. A contractor mounts the unit, connects it to the fuel supply, and ties it into the home's distribution system. The flue or vent pipe runs from the furnace to an exterior wall or roof to carry combustion gases out.

The air handler or blower compartment, which may be part of the furnace cabinet or a separate unit, pushes conditioned air into the supply side of the home. The thermostat goes on an interior wall and gives the homeowner control over the system. A contractor also installs or replaces the filter housing and any plenum sections that bridge the furnace to the duct openings.

The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
