A contractor quoting a heat pump install in Stewart County has to settle the sizing question before anything else, and the local weather record is one input to that. 84 severe weather events were recorded in Stewart County, Tennessee between 2015 and 2024. At that rate, severe weather is real but not a standing condition that overrides every other variable. What drives a good install here is accurate load calculation for the house, correct refrigerant line routing, and a commissioning check that confirms the system is actually hitting its rated output. Those are local craft questions, and no catalog spec answers them.
Ductwork laid down for a furnace and central air system handles airflow differently than a heat pump demands. Half the homes in Stewart County, Tennessee were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump in older stock here checks whether the existing duct runs, their sizing, and their condition can move the volume and velocity the new system requires. If they cannot, the ductwork becomes the larger part of the job. The electrical service gets the same scrutiny, since a heat pump draws on a circuit that older panels were not always wired to feed.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or bracket beside the house, and it holds the compressor and the outdoor coil. Inside, the air handler sits in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units are what a heat pump installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two along an exterior wall and into the structure. A thermostat goes on an interior wall and gives the homeowner control over the system. Some installations also include a supplemental electric resistance strip inside the air handler for the coldest nights.
