Sizing a heat pump for Cabarrus County is a local question, not a catalog one. 100 severe weather events were recorded in Cabarrus County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor quoting an installation has to build that load into the sizing calculation, the equipment selection, and where the outdoor unit sits on the property. A system undersized or poorly positioned for what this area actually delivers will run harder and recover more slowly every time conditions push it. Getting those decisions right at installation is cheaper than correcting them later.
Ductwork laid down for a furnace and central air setup handles air differently than a heat pump does, and in Cabarrus County a significant share of the housing was built when that older equipment was the standard. Half the homes in Cabarrus County, North Carolina were built in 1997 or earlier (2020-2024 ACS 5-year). A contractor assessing a heat pump installation here opens the existing duct runs and checks their capacity before anything else, because ductwork that cannot move the right volume of air will undercut whatever unit gets installed. The electrical panel gets the same look, since heat pumps draw differently than the systems many of these houses were originally wired for.
What Gets Installed With a New Heat Pump
The outdoor unit 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 contains the second coil along with the blower that moves conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. A thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one fits the configuration of your house.
