A furnace installation in Houston County has to be sized for what the system will actually run against. 248 severe weather events were recorded in Houston County, Alabama between 2015 and 2024. At that rate, severe weather is a standing operating condition, and a contractor who treats it as background noise will underspec the equipment. Duct layout, unit capacity, and the quality of sealing decisions all shift when the climate pushes heating loads hard on a regular basis. A catalog spec from a milder region is the wrong starting point here.
Ductwork is what decides whether a furnace installation goes straight or sideways. Half the homes in Houston County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). Houses from that era were ducted around equipment with different output profiles, and a modern furnace draws differently through the same trunk lines. Before a price is real, a contractor opens the system and checks what the existing duct network will actually carry. If it will not carry a new unit without modification, that work gets scoped and priced first.
What Gets Installed With a New Furnace
The furnace itself sits in a utility space, basement, or dedicated closet and is the unit that produces heat for the house. A burner assembly inside it ignites fuel, and a heat exchanger transfers that heat to the air before it moves anywhere else. The flue pipe runs from the furnace to an exterior wall or roofline and carries combustion gases out of the house.
The air handler, which may be part of the furnace cabinet or a separate unit, moves conditioned air into the duct system. The thermostat mounts on an interior wall and is the control point a homeowner touches directly. A contractor also connects the furnace to the gas line and to the home's existing return-air path so the system runs as one unit.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.
