Sizing a heat pump for this county means working out what happens when outdoor temperatures drop far enough that the refrigerant cycle alone cannot keep up. Homes in Yalobusha County, MS run heat about five months a year, from November through March. A contractor calculating the load here has to establish the backup heat threshold for this specific house, because a system that leans on resistance strips through the coldest weeks costs the homeowner considerably more to run than one sized to carry the heating load on its own as long as possible. The heat exchanger and compressor log real hours through those months, and an install that gets the refrigerant charge or the airflow wrong will show the strain before long.
Ductwork laid out for older equipment rarely lines up with what a heat pump wants from the house. The runs, the return sizing, the static pressure the system has to push against: these were set by a unit that is gone, and they do not automatically suit what is going in now. Half the homes in Yalobusha County, Mississippi were built in 1981 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here opens the question of whether those ducts stay, get modified, or get replaced before the unit is ever priced. Electrical service gets the same look, because the draw of a modern heat pump can land outside what the existing panel was set up to handle.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a concrete pad or wall bracket outside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, an air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying the refrigerant that makes the exchange possible. A thermostat on an interior wall gives the homeowner control over the whole system, and a condensate drain line runs from the air handler to carry away moisture pulled from the indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.
