A heat pump going into a Bradley County home is being sized for a place where severe weather is a regular part of operating life, not an occasional footnote. 86 severe weather events were recorded in Bradley County, Tennessee between 2015 and 2024. A contractor quoting an install here works out where that load falls hardest before settling on equipment capacity, refrigerant line routing, or mounting decisions. Getting those choices wrong in a lower-demand area might cost a homeowner efficiency; getting them wrong here puts the system under sustained pressure from day one.
Ductwork laid down for a furnace and central air setup carries assumptions about airflow, return sizing, and routing that a heat pump does not share. Half the homes in Bradley County, Tennessee were built in 1986 or earlier (2020-2024 ACS 5-year). That spread across the housing stock means a contractor pulling permits here regularly opens walls or crawlspaces to check what the existing duct system actually delivers before the new unit is specified. If the ducts cannot move the volume a heat pump needs at the right static pressure, the equipment choice follows from that finding. Electrical service gets the same look, since a heat pump's draw has to match what the panel can handle.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners recognize first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which do the core work of moving heat between the refrigerant and the outside air. 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 ceiling. 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 how each piece fits the conditions of your house.
