A contractor quoting a central AC install in Bedford County has to account for what the climate actually demands before settling on equipment size. 132 severe weather events were recorded in Bedford County, Tennessee between 2015 and 2024. At that rate, severe weather is a standing condition of operating a cooling system here, not an occasional disruption, and a unit sized for mild conditions will run harder and longer than it was built to. A contractor who treats sizing as a catalog exercise will land on the wrong unit.
Existing ductwork in a house this age was sized and routed for whatever ran in it originally, and that original layout shapes every decision a contractor makes about a new central system. Half the homes in Bedford County, Tennessee were built in 1990 or earlier (2020-2024 ACS 5-year). Ducts that have been patched, rerouted, or left untouched since the house was built may not move the volume a new unit expects, which changes both what the contractor can quote and what they have to open before they can quote it. The electrical service raises the same question: whether what is already in the panel supports the load a new system draws is something a contractor has to verify on site, not estimate from the address.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it is the unit that moves conditioned air through the home. The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil. These two units are the core of what a contractor installs.
A refrigerant line set runs between the indoor and outdoor units, carrying refrigerant back and forth through insulated copper tubing. The thermostat mounts on an interior wall and serves as the control point for the whole system, telling it when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific home.

What the Installation Actually Looks Like
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.
