A contractor quoting central AC installation in Bledsoe County starts with the house: its square footage, insulation, duct layout, and how the existing system was sized. 62 severe weather events were recorded in Bledsoe County, Tennessee between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing operating condition, which means the installation decisions that matter most are about the building rather than about bracing for relentless weather load. A contractor who gets the Manual J load calculation right for this house will size equipment that fits the actual demand.
Ductwork sized for equipment from a previous era does not automatically carry a modern central AC system well. Half the homes in Bledsoe County, Tennessee were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor installing a new unit here has to assess what the existing ducts can handle before anything else gets priced, because the routing, the sizing, and the connections were built around whatever the house ran before. The electrical panel gets the same look. A new system draws what it draws, and the service in a house of this vintage was not necessarily wired with that in mind.
What a Central AC Installation Covers
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility room, basement, or attic and is the indoor half of the system. Together these two units are what a contractor installs.
The refrigerant line set runs between the two units, connecting the outdoor and indoor sides through a small penetration in the wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Both pieces are part of what the installation covers.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires in your 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.
