A contractor quoting a heat pump install in Graham County is not sizing around a climate that regularly tests equipment to its limits. 32 severe weather events were recorded in Graham County, North Carolina between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing condition the system fights through every season. What shapes the right install is the age of the structure, how well the ductwork was laid, and whether the original equipment was correctly sized for the house. A unit put in badly fails in a mild county just as fast as anywhere else.
Ductwork laid down for a furnace or central air system carries assumptions about airflow, return paths, and static pressure that a heat pump does not share. Half the homes in Graham County, North Carolina were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation in a house from that era spends time in the crawlspace and the attic measuring what is already there, because the ducts determine whether the system performs as rated or fights itself from day one. The electrical panel gets the same look: heat pumps draw differently than what the original service was sized around. What the house already contains is where the installation either straightens out or gets complicated.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, a metal cabinet set on a pad outside the house that holds the compressor and one set of coils. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor brings to the job.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two cabinets through the wall or floor. A thermostat goes on an interior wall where it reads the air temperature and tells the system when to run. Together these pieces make up the full installation.
The drawing shows a representative layout, and a licensed contractor determines exactly what fits and where in your particular house.

Severe Weather Events in Graham County
Graham County's climate puts real demands on heating and cooling equipment, and those demands vary with how hard the weather runs year to year. A heat pump sized and installed for local conditions handles that load better than one spec'd from a national average.
