A contractor quoting central AC installation in Claiborne County has to start from what this house actually needs, not from a catalog spec. 78 severe weather events were recorded in Claiborne County, Tennessee between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means the climate alone does not drive sizing decisions the way it does in harder-hit areas. What drives them instead is the building itself: its age, its insulation, its ductwork, and how the previous equipment was set up. A contractor who skips that assessment and pulls a unit off a price sheet will leave the system undersized or oversized, and no amount of storm history explains a comfort problem that traces back to the install.
Ductwork laid for older equipment carries a different set of assumptions about airflow than a modern central AC system needs. Half the homes in Claiborne County, Tennessee were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to open access points and check what the existing runs can actually move before the new unit is ever ordered. If the ducting cannot handle the load, that is where the job grows, not at the air handler itself. The electrical service gets the same look, since what a house of that era was wired to carry and what current equipment draws are questions a contractor answers before anything is priced.
What a Central AC System Includes
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it circulates air across a coil that conditions it before sending it through the house. The outdoor condenser unit sits on a pad beside the house and holds the compressor and the condenser coil.
A copper refrigerant line set runs between those two units, connecting the indoor coil to the outdoor one. The thermostat mounts on an interior wall and tells the system when to run, acting as the single point of control a homeowner touches.
The drawing shows how these pieces relate in a typical layout, and a licensed contractor determines exactly what fits and where in your home.

What the installation looks like in Claiborne County
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
