A contractor sizing and installing central AC in Weakley County has to account for what this area actually puts equipment through, and the honest answer is that severe weather here is real but not relentless. 80 severe weather events were recorded in Weakley County, Tennessee between 2015 and 2024. At roughly that rate, most systems in the county spend the bulk of their service life in ordinary summer heat, which means installation quality and equipment sizing carry more weight than weather hardening. A sloppy refrigerant charge or an undersized air handler will cost a homeowner far more than the occasional hard storm. Contractors who know this area price and spec the install accordingly.
Ductwork laid down for an older system carries assumptions about airflow, load, and routing that a new central AC unit does not share. Half the homes in Weakley County, Tennessee were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess whether those runs can actually deliver what the new equipment is rated for, and whether the electrical service the house already has will support it. Some of it will. Some will need correction before the unit goes in.
What a Central AC System Includes
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the pieces that shed heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and holds the evaporator coil that cools the air moving through it. Together these two cabinets are what a Central AC installation puts in place.
The refrigerant line set runs between the two cabinets, carrying refrigerant back and forth through insulated copper tubing that passes through the wall. A thermostat on an interior wall ties the whole system together, reading the temperature in the house and telling the equipment when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

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.
