A contractor quoting a central AC installation in Geneva County has to size for what this area actually runs against, not what a manufacturer's chart assumes. 173 severe weather events were recorded in Geneva County, Alabama between 2015 and 2024. At that rate, severe weather is part of the normal season here, not an outlier, and a system sized without accounting for sustained weather load will be undersized for the work it actually faces. The refrigerant line routing, the unit placement, and the electrical supply all get spec'd against local conditions that a generic install guide does not reflect.
Ductwork laid down for an older system carries assumptions about airflow, routing, and load that a new central AC unit does not share. Half the homes in Geneva County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess whether the existing duct system can handle what the new equipment will push through it, and whether the electrical service will support it, before the unit itself enters the conversation. Some houses need only minor adjustments; others require the contractor to reprice the job once the walls and attic tell the actual story.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the two components 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, which does the cooling work on the air before it moves through the home.
A refrigerant line set runs between the outdoor unit and the indoor cabinet, carrying refrigerant between the two. A condensate drain line runs from the indoor cabinet to a floor drain or outside, clearing the moisture the evaporator coil pulls from the air. The thermostat mounts on an interior wall and is the control point for the whole system.
The drawing shows a standard layout, and a licensed contractor determines what applies to your specific house.

What HVAC Installation Looks Like in Geneva 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 Rules for HVAC Work in Geneva 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 Geneva County
Weather extremes put real strain on cooling equipment, shortening its life and widening the gap between a correctly sized system and one that falls short. Central AC installation in Geneva County is a local decision partly because the local climate shapes what the equipment has to handle.
