A contractor quoting a heat pump installation in Scott County has to work out what the house actually demands before settling on equipment size or configuration. 72 severe weather events were recorded in Scott County, Tennessee between 2015 and 2024. At that rate, severe weather is a real presence but not so relentless that it drives every installation decision. What drives those decisions is the structure itself: insulation, duct layout, ceiling height, and the load profile the building puts on a system year-round. A contractor who skips that assessment and pulls a size from a catalog will underspec or overspec the unit, and no weather record fixes a wrong-sized install.
Ductwork laid for one era's equipment does not automatically serve the next. Half the homes in Scott County, Tennessee were built in 1988 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than the systems those ducts were designed around, and a contractor installing one here checks whether the existing runs, returns, and register sizes will carry the load before anything else on the job is priced or ordered. If the ductwork cannot support it, that work comes before the unit goes in.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house. It holds the compressor and the outdoor coil, and it is where the system pulls heat from the outside air or releases it, depending on the season. The indoor air handler mounts in a utility closet, attic, or basement and circulates conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing along the exterior wall or through a chase inside the house. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include an auxiliary heat strip inside the air handler for the coldest days.
The drawing shows a typical layout, and a licensed contractor determines what fits this particular house.
