A contractor sizing and installing a heat pump here has to account for what this climate actually puts equipment through. 84 severe weather events were recorded in Granville County, North Carolina between 2015 and 2024. At that rate, severe weather is a recurring feature of operating in this county, not a rare disruption, and a system sized or installed loosely will feel it over time. Refrigerant line work, electrical connections, and outdoor unit placement all need to be right from day one, because accumulated load finds the weak points in a careless install before the equipment ever reaches its expected service life.
Ductwork laid down for older cooling and heating equipment was designed around different airflow volumes than a heat pump moves, and in Granville County that gap shows up on installation day. Half the homes in Granville County, North Carolina were built in 1992 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here measures the existing duct runs, checks their sizing against what the new unit requires, and decides what has to be rebalanced or replaced before the system can perform as rated. The electrical service gets the same attention. Those two variables, not the equipment selection itself, are where the scope and the price of the job actually settle.
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 beside the house and holds the compressor and one set of coils. Inside, an air handler mounts in a closet, utility room, or attic and moves 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 through insulated copper tubing along an exterior wall or through the attic. 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 which components and configurations apply to this house.
