A contractor sizing or installing central AC here needs to account for what the local climate actually asks of a system, and the weather record keeps that question honest. 69 severe weather events were recorded in Hale County, Alabama between 2015 and 2024. At that rate, severe weather is an event in this county rather than a constant condition, which means age, installation quality, and how well the original equipment was matched to the load are the factors that drive what a system costs to run and how long it lasts. A contractor quoting a new install here sizes for the climate as it is, not as it might be imagined from a rougher county.
Ductwork laid down for a previous generation of equipment carries assumptions about airflow, sizing, and sealing that a new central AC system will test from day one. Half the homes in Hale County, Alabama were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation in stock this age has to open and measure what is already in the walls before the equipment selection means anything, because undersized or leaking duct runs will cap the performance of whatever unit goes in. The electrical service gets the same scrutiny: older panels were not wired with modern cooling loads in mind, and a new system that draws more than the service supports requires panel work before the install can finish.
What Gets Installed With a New Central AC
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 stands in a utility space, basement, or attic and contains the evaporator coil and blower that move conditioned air through the home.
The refrigerant lines run between the outdoor and indoor units, connecting the two halves of the system through the wall or floor. A thermostat goes on an interior wall and gives the homeowner control over the whole system, while a disconnect box mounts near the outdoor unit to allow the contractor a safe shutoff point.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What HVAC Installation Looks Like in Hale 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.
Licensing and Legal Requirements in Hale County, Alabama
Alabama requires state certification to do heating, air conditioning and refrigeration contracting: nobody may advertise, bid, pull permits or do the work unless the person in responsible charge is a certified contractor.
Severe Weather Events in Hale County
Alabama's climate puts real pressure on cooling equipment, and Hale County gets its share of the weather patterns that drive that load. How hard a system has to work over its life is partly a local question, and that makes storm history relevant to any conversation about what to install and how to size it.
