Sizing a heat pump for this county starts with the heating side, because that is where the system earns its keep or falls short. Homes in Claiborne County, MS run heat about five months a year, from November through March. As outdoor temperatures drop through those months, a heat pump's capacity drops with them, and the backup resistance element picks up whatever the refrigerant circuit cannot. A contractor who skips a proper load calculation here will quote a unit that looks adequate on paper but leans on that backup strip far more than the homeowner expects, driving up bills and wearing the electrical components harder.
Ductwork sized and sealed for an older central system behaves differently under the airflow pattern a heat pump runs on, and that gap is where most heat pump installations in this county meet their first real complication. Half the homes in Claiborne County, Mississippi were built in 1982 or earlier (2020-2024 ACS 5-year). A house in that range of the distribution was built around equipment long since replaced, and the duct layout it still carries reflects the delivery pressures and room-by-room balance of what came before. A contractor putting in a new heat pump has to assess what those ducts will actually do under the new system's draw before anything else on the job can be priced accurately.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the heat exchange coil, which together do the work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, attic, or closet and pushes conditioned air through the home's supply vents.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing that a contractor routes along the exterior wall or through the framing. A thermostat goes on an interior wall and gives the household a single point of control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines what applies to your house specifically.
