A contractor quoting a central AC installation in Hickman County has to size for a climate that works the equipment hard on a regular basis. 97 severe weather events were recorded in Hickman County, Tennessee between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, not an occasional variable, and equipment sized without accounting for it will run harder than the specs assumed. A contractor who treats local weather load as a footnote to the nameplate calculation produces an install that is undersized for what the house will actually demand.
Ductwork laid down for older, lower-capacity equipment does not automatically carry a modern central AC system. Half the homes in Hickman County, Tennessee were built in 1989 or earlier (2020-2024 ACS 5-year). When a contractor quotes a new installation here, the existing duct runs, their diameter, and how they were originally laid out determine whether the system will perform or struggle. Electrical service follows the same logic: what a house was wired to handle and what a new unit draws are questions that get answered with a panel inspection, not an assumption. The duct evaluation often decides the project before the equipment selection does.
What a Central AC Installation Covers
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace cabinet lives in a utility space, basement, or attic and houses the evaporator coil, which is where the air in your home actually gets treated.
The thermostat mounts on an interior wall and is the control point for the whole system, telling the equipment when to run and when to stop. A condensate drain line runs from the indoor cabinet to a floor drain or outside, carrying away the moisture the evaporator coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home's configuration.

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.

Severe Weather Events in Hickman County
Weather puts a measurable load on cooling equipment, and that load is shaped by what actually happens in this area. A contractor sizing and installing central AC here works from local conditions, not a national average.
