A contractor quoting a heat pump install in Duplin County has to size the system against what the climate actually demands, not against a catalog default. 101 severe weather events were recorded in Duplin County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, and a system undersized or poorly sealed against it will struggle from the start. Refrigerant line placement, weatherproofing at the penetrations, and unit siting all carry more weight in a county with a record like this than they would somewhere the weather rarely pushes hard.
Ductwork laid down for an older system and never touched since is what shapes how a heat pump installation goes here. Half the homes in Duplin County, North Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than what most of that stock was originally set up to handle, and ducts that were routed, sized, and sealed for something else may not distribute the way the new equipment needs. An electrical service from that same era is the second thing a contractor opens before pricing anything. The unit itself gets selected last, once what the house actually has is known.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, set on a pad beside the house. It holds the compressor and the outdoor coil, and it is where the system does the bulk of its work pulling heat from or releasing heat to the outside air. Inside the house, the air handler mounts in a closet, attic, or utility space and moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler through the wall or floor. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a secondary electric heat strip inside the air handler for periods of very cold weather.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of this particular house.

Severe Weather Events in Duplin County
Heating and cooling loads are shaped by what the local climate actually does, not what an average suggests. A heat pump sized and installed for Duplin County's real weather profile holds up through conditions that would stress a system built to a looser standard.
