Sizing a heat pump for Leake County means solving for the hard end of the range before anything else. Homes in Leake County, MS run heat about five months a year, from November through March. As outdoor temperatures fall through those months, a heat pump loses capacity, and a contractor has to establish how far that drop goes on the coldest nights before they can choose a unit or set a backup heat strip. A system sized to the mild days runs its resistance backup hard when temperatures bottom out, and resistance heat is expensive to run. The installer's load calculation has to land on the right balance between refrigerant capacity and backup heat, because getting it wrong shows up on every winter utility bill.
Ductwork laid out for a different system shapes what a heat pump installation actually costs here. Half the homes in Leake County, Mississippi were built in 1982 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a new unit has to assess what the existing duct network will carry before anything else on the job is priced. Runs that were routed for one kind of equipment, sealed to one standard, and never touched since can restrict airflow in ways that change the scope of the install. The electrical service gets the same look: what a heat pump draws has to match what the panel was built to handle.
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 main coil. The indoor air handler mounts inside, usually in a utility closet or basement, and moves conditioned air through the home. Together these two units do the work the system was bought to do.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid back and forth through insulated copper tubing. A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Weather puts a measurable load on heating and cooling equipment, and that load varies by where you live. A heat pump sized and installed for what Leake County actually sees will perform differently than one built around someone else's climate.
