A contractor quoting a heat pump installation in Lenoir County starts by sizing the system to what this climate actually demands, not to a regional average. 61 severe weather events were recorded in Lenoir County, North Carolina between 2015 and 2024. At that rate, severe weather touches a system here, but it does not define the system's working life the way it would in a county where such events are constant. What that means for installation is that the quality of the original work carries more weight than weatherproofing choices do. A unit set in concrete with proper refrigerant charge and correctly sized ductwork will outlast one installed carelessly, regardless of what any given season brings.
Ductwork laid down for older equipment carries assumptions a heat pump does not share, and in Lenoir County a large share of the housing was built well before residential heat pumps became standard. Half the homes in Lenoir County, North Carolina were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing a new unit here runs into that gap at the duct level: static pressure, trunk sizing, and register placement were set for a different kind of system. Electrical service is a separate check. But it is the existing ductwork that most often decides whether an installation is straightforward or whether a significant portion of the job is behind the walls rather than at the air handler.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a concrete pad or wall bracket outside the house and holds the compressor and one set of coils. Inside, the air handler mounts in a closet, attic, or utility room and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your house.
