Sizing a furnace for a house in Henry County starts with the structure: its age, its insulation, how it sits on the lot. 62 severe weather events were recorded in Henry County, Georgia between 2015 and 2024. At that rate, severe weather is an occasional event rather than a constant operating condition, which means the load the county's climate puts on a heating system is not what drives the install decision. What drives it is the house. A contractor here has to measure and calculate for that specific building, because a catalog guess in either direction leaves the homeowner paying to correct it.
Ductwork laid down for an older furnace carries its own assumptions about airflow, load, and trunk sizing. Half the homes in Henry County, Georgia were built in 2001 or earlier (2020-2024 ACS 5-year). A contractor quoting a new furnace here has to assess what those ducts will actually do with a modern unit pushing through them, which is a separate question from which furnace to buy. If the runs are undersized or the layout fights the new equipment, the duct work drives the scope. The furnace selection comes after that answer, not before.
What a Furnace Installation Puts in Your Home
The furnace itself sits in a utility space, basement, or closet and is the unit that generates heat for the house. A contractor sets the air handler inside that same unit or nearby, depending on the configuration, and it is the piece that moves conditioned air into the duct system.
The flue pipe runs from the furnace to an exterior wall or the roof and carries combustion gases out of the house. The thermostat mounts on an interior wall and is the control point that tells the furnace when to fire and when to stop.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home and setup.

Severe Weather Events in Henry County
Weather extremes put real hours on heating and cooling equipment, and those hours add up differently depending on where a home sits. A furnace sized and installed for local conditions handles that load better than one spec'd for somewhere else.
