A contractor quoting a central AC installation in Winston County is not working against a punishing storm record. 75 severe weather events were recorded in Winston County, Alabama between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing condition the equipment fights through every season. What drives sizing decisions and installation choices is the summer cooling load, the layout of the house, and the ductwork the system has to move air through. A rushed or undersized install will fail here for the same reasons it fails anywhere.
Ductwork laid down for an older system carries assumptions about airflow, routing, and capacity that a new central AC unit does not share. Half the homes in Winston County, Alabama were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing a new system has to assess what those ducts will actually deliver before anything gets ordered, because a mismatch between the existing ductwork and a modern unit's requirements means the installation either gets rerouted or the system underperforms from day one. The electrical service gets the same check: older panels were not built to the draw a current system expects.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad beside 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 mounts in a utility closet, basement, or attic and houses the evaporator coil and the blower that moves air through the home.
A refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and what temperature it holds.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to 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.
Licensing Rules for HVAC Work in Winston 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 Winston County
Alabama's climate puts real stress on cooling equipment, and Winston County gets its share of what that climate delivers. How hard the weather pushes here shapes what a central AC system has to handle and how long it holds up doing it.
