Sizing a furnace for Franklin County starts with understanding what the burner and heat exchanger are actually asked to carry. Homes in Franklin County, AR run heat about seven months a year, from October through April. A system that is undersized for that load cycles harder and more often, and the ignition system and heat exchanger accumulate wear on a schedule that a generous idle period never interrupts. A contractor quoting a replacement here runs a proper load calculation before selecting equipment, because a unit that fits the house on paper but not the season will show stress at the heat exchanger long before its rated service life is up.
Ductwork in a house like many here was designed around whatever heating system the builder put in, and that system is gone. What remains is a distribution network sized for different airflow rates than a modern furnace produces, and whether it can carry the new load is the question a contractor has to settle before the equipment selection means anything. Half the homes in Franklin County, Arkansas were built in 1985 or earlier (2020-2024 ACS 5-year). A trunk line that is too restrictive forces a contractor to either resize the ductwork or select equipment that fits the existing runs, and those are different jobs with different costs. The electrical service gets the same check: a new furnace draws what it draws, and the panel has to back it.
What a Furnace Installation Covers
The furnace itself sits inside the house, most often in a basement, utility room, or closet, and it is the unit that generates heated air and pushes it through the home. Alongside it, the air handler or blower assembly moves that air into the supply side of the house.
The flue or exhaust vent runs from the furnace to the outside of the house and carries combustion gases out. The thermostat mounts on an interior wall and serves as the control point, telling the furnace when to fire and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
