Sizing a heat pump for St. Francis County means accounting for what happens at the low end of January, not just the shoulder months. Homes in St. Francis County, AR run heat about five months a year, from November through March. A heat pump loses capacity as outdoor temperatures drop, so a unit sized loosely will lean on its electric backup strips through the coldest weeks rather than handling the load on the refrigerant circuit alone. The contractor has to run a proper load calculation against actual local conditions before the equipment is ever ordered, because an undersized system shows the gap immediately in a county where winter runs this long.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow that a heat pump does not share. Half the homes in St. Francis County, Arkansas were built in 1980 or earlier (2020-2024 ACS 5-year). A heat pump installation in housing stock like this turns on what the existing ducts will actually do with the new load, not just whether they are present. A contractor who finds undersized or leaking duct runs is looking at a different scope of work than the equipment cost suggests.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the core work of the system. Inside, an air handler or indoor coil mounts in a closet, utility room, or attic and connects to your existing duct system to move conditioned air through the house.
A refrigerant line set runs between the two units, carrying the working fluid that links the outdoor and indoor sides. A thermostat on an interior wall is what the homeowner sees and touches, and a disconnect box near the outdoor unit lets a contractor cut power to that side of the system safely.
The drawing beside this text shows the general layout of these components, and a licensed contractor determines exactly how they fit the conditions of your specific home.
