A contractor sizing a heat pump in Columbus County has to answer questions the equipment catalog cannot answer on its own. 110 severe weather events were recorded in Columbus County, North Carolina between 2015 and 2024. At that rate, severe weather is a real but not dominant factor in how hard the system runs over its life, which means the decisions made on installation day carry more weight than the climate does. A unit that is undersized or poorly charged from the start will degrade faster than one that met a rough season or two. Getting the load calculation and refrigerant charge right at install is what determines how the equipment holds up.
Ductwork laid down for older heating systems was designed around different airflow demands than a heat pump puts on it. Half the homes in Columbus County, North Carolina were built in 1982 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a new heat pump here has to look hard at what is already in the walls and crawlspaces before the equipment question is even worth answering. A panel check matters too, since the electrical service in houses of that age was not planned around the loads a modern heat pump draws. The unit itself is straightforward to spec; getting it to run right through the existing infrastructure is where the job gets decided.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or wall bracket beside the house, and it holds the compressor and the outdoor coil. Inside, the air handler sits in a closet, attic, or utility room and moves conditioned air through the home. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing along the exterior wall and into the home. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The disconnect box, mounted near the outdoor unit, allows the contractor to cut power to that unit safely.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and configured for your specific house.

Severe Weather Events in Columbus County
Weather puts load on heating and cooling equipment, and that load is shaped by local conditions. A heat pump sized and installed for what Columbus County actually sees will hold up better than one spec'd for somewhere else.
