Sizing a heat pump for a Macon County home is a local question, and the weather record is one part of what a contractor has to weigh before settling on equipment. 39 severe weather events were recorded in Macon County, Alabama between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means it does not drive the sizing calculation the way it might in a harder-hit area. What does drive it is the age and construction of the house, the existing ductwork, and how the building holds or loses air. A contractor who skips that audit and quotes off square footage alone will get the unit wrong.
Ductwork laid down for a central air system or a furnace was sized and routed for that system's airflow, not for a heat pump's. Half the homes in Macon County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump in housing of this vintage has to assess whether the existing ducts can move the volume a heat pump delivers at the static pressure it produces, and whether the electrical service will carry the load the new unit draws. Both are opening questions before anything gets quoted or ordered.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first, a cabinet that sits on a concrete pad or wall bracket beside the house and holds the compressor and one set of coils. Inside, the air handler mounts in a closet, attic, or utility space and moves conditioned air through the home. Together these two units are what a new heat pump installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two along an exterior wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include an auxiliary heat strip inside the air handler, which a contractor sizes and positions based on the house.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits your home.

Severe Weather Events in Macon County
Weather swings drive how hard heating and cooling equipment works and how long it lasts. A heat pump sized and installed for local conditions holds up better than one spec'd without that picture in mind.
