Sizing a heat pump for Calhoun County means settling the back-up heat question before anything else. Homes in Calhoun County, MS run heat about five months a year, from November through March. Through those months, outdoor temperatures fall low enough that a heat pump's output shrinks at exactly the moment the house needs it most. A contractor running a load calculation here has to establish where that crossover point lands for the specific house, then decide what carries the load below it. Get the sizing wrong, and the system runs at a deficit on the coldest nights every winter. The installer's choice of back-up capacity is the decision that keeps the system from falling short.
Ductwork laid down for a central system that is no longer in the house, and a service panel sized for loads that predate modern heat pump equipment, are what a contractor runs into before the installation conversation can move forward. Half the homes in Calhoun County, Mississippi were built in 1980 or earlier (2020-2024 ACS 5-year). That gap between when the house was wired and what a heat pump actually draws is where installation quotes get complicated. A panel that cannot carry the new load has to be upgraded first, and that work sets the scope and the cost before the equipment selection does.
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 coil that exchange heat with the outside air. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor places during an installation.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two so they can work as one system. A thermostat goes on an interior wall where it can read the living space and signal the system to run. A condensate drain line also runs from the air handler to carry away moisture the indoor coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your home.
