Sizing a heat pump for Buncombe County starts with what the climate asks of it. 88 severe weather events were recorded in Buncombe County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, and a contractor who ignores it will size the system for conditions that do not exist here. Duct connections, refrigerant lines, and outdoor unit placement all get specified against what this area actually runs through. A unit sized for a gentler load will cycle harder and wear faster in a county where the weather is this consistent.
Existing ductwork is what a contractor prices carefully before anything else on a heat pump installation in Buncombe County. Half the homes in Buncombe County, North Carolina were built in 1991 or earlier (2020-2024 ACS 5-year). Ductwork laid down for a furnace-and-central-air setup was sized and routed for a different kind of load, and a heat pump moves air at lower temperatures across longer run times. What fits one system does not automatically fit the other. The electrical service is a separate check, since the panel has to support the draw of a modern heat pump. Both are variables the contractor has to measure, not assume.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, a metal cabinet that sits on a pad beside the house and holds the compressor and one set of coils. Inside, an air handler mounts in a closet, attic, or utility room and contains the second set of coils along with a blower that moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing that a contractor routes 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 fits the configuration of your house.
