A contractor quoting a heat pump installation in Crockett County is not sizing against a system battered by constant severe weather. 36 severe weather events were recorded in Crockett County, Tennessee between 2015 and 2024. At that rate, severe weather is an occasional fact of life rather than a steady operating pressure, so the decisions that determine how well a heat pump performs here come down to site conditions, correct sizing for the structure, and the quality of the install itself. Those are the variables a contractor works through before the equipment is ever ordered.
Ductwork laid down for a different era of heating and cooling was not built to move air the way a heat pump moves it. Half the homes in Crockett County, Tennessee were built in 1979 or earlier (2020-2024 ACS 5-year). That gap between when a house was framed and what a contractor is now asked to put into it is where a heat pump installation either fits cleanly or does not, and the answer lives in the ducts, not on the spec sheet for the new unit. A contractor measures static pressure, checks trunk sizes, and looks at how the runs were laid before the equipment question is settled.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a concrete pad beside the house and holds the compressor and the condenser coil, the two components that do the bulk of the work. Inside, the air handler mounts in a utility closet, basement, or attic and pushes conditioned air through the home. Both units ship together as a matched system and get set in place during the same installation.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat mounts on an interior wall and serves as the control point for the whole system. Some installs also include an auxiliary heat strip inside the air handler, which a contractor fits depending on what the house requires.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your home.

Severe Weather Events in Crockett County
Weather in this part of Tennessee puts real demands on heating and cooling equipment, and those demands shape what a heat pump needs to handle over its working life. Sizing and installing equipment without accounting for local conditions is how you get a system that underperforms when it matters most.
