A contractor quoting a heat pump install in Obion County is working out fit and placement before anything else. 85 severe weather events were recorded in Obion County, Tennessee between 2015 and 2024. At that rate, severe weather is a real but infrequent pressure on equipment here, which means the variables that drive a system toward early failure are the ones a contractor controls at the install: refrigerant charge, duct sizing, airflow, and how well the unit is matched to the house's actual load. A poor install in this county will cost a homeowner more over time than the weather ever will.
Ductwork laid out for a gas furnace or a window unit was not designed around the air-handling requirements a heat pump places on it. Half the homes in Obion County, Tennessee were built in 1975 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a new system here has to evaluate what the existing duct runs can actually move before the equipment choice is settled, because undersized or poorly routed ducts will limit what any new unit delivers regardless of its rated capacity. The electrical panel is the second check: service that predates modern heat pump installations often needs an upgrade before the new unit can run at all.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, a metal cabinet set on a pad beside the house that holds the compressor and one set of coils. Inside the house, the air handler mounts in a closet, attic, or utility room and moves conditioned air through the home. Together these two cabinets are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid back and forth through insulated copper tubing. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. Some installations also include a supplemental electric heat strip inside the air handler for the coldest stretches of winter.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
