A contractor quoting a heat pump installation in Shelby County has to account for a climate that puts sustained demand on equipment season after season. 269 severe weather events were recorded in Shelby County, Tennessee between 2015 and 2024. At that rate, severe weather is part of the normal operating life of any system installed here, and it shapes the sizing calculation before a single component gets chosen. A unit specced for average regional conditions and installed without attention to how hard this climate runs equipment will be undersized in practice. The load the area carries is the starting point, and the install has to be built around it.
Ductwork designed for a different kind of system and electrical service sized for what was standard at the time of construction are what a contractor is working with in a large share of Shelby County homes. Half the homes in Shelby County, Tennessee were built in 1977 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than the equipment that ductwork was originally built around, and it draws on the electrical service in ways that what was installed decades before may not accommodate without modification. Those two variables, the ducts and the panel, are what a contractor has to evaluate and price before the equipment choice settles anything.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad beside the house. Inside, the air handler sits in a utility closet, attic, or basement and pushes conditioned air through the home. Together, these two units do the core work of the system.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two units act as one system. A thermostat goes on an interior wall and gives the homeowner control over the whole setup. Most installations also include a disconnect box near the outdoor unit.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one fits the configuration of your particular house.

Severe Weather in Shelby County
Weather puts real demands on heating and cooling equipment, and those demands vary by location. How hard a heat pump works across its life is shaped by what the climate throws at it, which is why local weather history matters when sizing and installing equipment in Shelby County.
