Sizing a furnace for this county is not a generic calculation. Homes in Chicot County, AR run heat about five months a year, from November through March. The burner and heat exchanger cycle through every one of those months, and a unit that is undersized or has loose duct connections runs harder and hotter than the manufacturer's design assumes. A contractor quoting a new installation here has to account for that full load when selecting equipment and sealing the distribution system, because the idle period is short enough that wear has little time to stay hidden.
Ductwork sized for a previous generation of equipment is what a contractor measures before anything else in a furnace installation here. Half the homes in Chicot County, Arkansas were built in 1979 or earlier (2020-2024 ACS 5-year). That shapes the job: the existing trunk lines, branch runs, and return paths were built for something, and whether what they were built for matches what a new furnace needs is a physical question answered with a tape measure and a load calculation, not from the outside of the house. Electrical service gets the same look, since a new furnace draws what it draws regardless of what the panel was originally sized to handle.
What a Furnace Installation Covers in Your Home
The furnace itself sits inside the house, most often in a basement, utility closet, or crawl space. It holds the burner, the heat exchanger, and the blower in a single cabinet. That cabinet is where a contractor works when fitting the new unit into the space.
The flue pipe runs from the furnace up and out of the house, carrying combustion gases outside. The thermostat mounts on an interior wall and signals the furnace when to fire. A condensate drain line also connects to high-efficiency units, routing moisture out of the cabinet.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
