A contractor quoting a heat pump installation in Sampson County starts with the climate, because severe weather here is frequent enough to be a standing condition for anything they put in the ground. 129 severe weather events were recorded in Sampson County, North Carolina between 2015 and 2024. At that rate, a system sized to a catalog default rather than to actual local conditions will be working harder than it was designed to from its first summer. Contractors who know this area size for what the equipment will actually face, not for a milder assumption.
Ductwork laid down for older heating systems carries assumptions about static pressure and airflow that a heat pump does not share. Half the homes in Sampson County, North Carolina were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here checks whether the existing runs can move the volume a new unit needs, and where they cannot, the duct work becomes a separate scope before the equipment is ever ordered. Electrical service is the other check: older panels often lack a dedicated circuit at the ampacity a heat pump draws. What the house already contains shapes the bid more than the unit itself does.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, a cabinet that sits on a concrete pad or wall bracket outside the house and holds the compressor and one set of coils. Inside, an air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home. These two units are what a contractor brings to the job.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two sides of the system talk to each other. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Both pieces are part of what a contractor installs alongside the main units.
The drawing beside this text shows the general layout of a heat pump system, and a licensed contractor determines exactly how each piece fits the conditions of your specific house.
