A heat pump going into a Martin County home has to be sized for what this area actually delivers, and that starts with the weather. 72 severe weather events were recorded in Martin County, North Carolina between 2015 and 2024. The compressor and refrigerant circuit will cycle against that kind of cumulative load over years, which is a reason a contractor runs a proper load calculation rather than pulling a unit size from a catalog. Still, the weather record here sits at a level where age and installation quality remain the primary variables a contractor has to price around. A unit that was undersized or poorly commissioned from the start will fail on that history faster than a well-installed one of the same model.
Ductwork in a house carries the signature of whatever it was originally built around, and in a county where the housing stock runs as old as Martin County's, that original equipment is long gone. Half the homes in Martin County, North Carolina were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here measures what the existing ducts can actually move and where the electrical service stands, because those two things, not the unit itself, determine the scope of the job. If the duct layout was cut for a different system, the new equipment will not perform to spec regardless of its rating.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad beside the house, and it holds the compressor and the outdoor coil. Inside, the air handler sits in a utility closet, basement, or attic and moves conditioned air through the home. Together these two units do the work of both heating and cooling.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant through insulated copper tubing along the exterior wall or through a chase. 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.
