A contractor quoting a heat pump installation in Hardeman County has to account for what the local climate actually demands before settling on equipment size or placement. 62 severe weather events were recorded in Hardeman County, Tennessee between 2015 and 2024. At that rate, severe weather is a real but infrequent variable, which means the sizing decisions that matter most here come down to the house itself: its age, its duct configuration, and how well a previous install was done. A system undersized for the structure will struggle every summer regardless of how quiet the skies have been.
Ductwork laid out for a different system carries assumptions about airflow, branch sizing, and return placement that a heat pump does not share. Half the homes in Hardeman County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). That puts the existing duct layout at the center of what a contractor has to assess before the new equipment is even priced. Electrical service matters too, and a licensed contractor checks it, but ductwork is where the fit between house and system either works or has to be corrected.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the condenser coil, which together do the heavy lifting of moving heat in or out depending on the season. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler through the wall or floor. The thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler for the coldest stretches.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned within it.
