A contractor quoting central AC installation in Franklin County has to size the system around what this area actually demands, and that question is answered by the local weather record before any catalog gets opened. 112 severe weather events were recorded in Franklin County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a system undersized or poorly sealed against it will run harder and recover slower from the start. Proper installation work accounts for that load from day one, because catching up later costs more than getting it right initially.

Ductwork sized and routed for older equipment does not automatically carry a modern central AC system. Half the homes in Franklin County, Alabama were built in 1983 or earlier (2020-2024 ACS 5-year). That gap between when these houses were built and what contractors now install in them is where most of the real decisions on an installation job live. A contractor has to assess whether the existing duct runs can handle current airflow demands, and whether the electrical service will support what the new unit draws. If either falls short, that work gets priced and scheduled before the equipment question is even settled.
What Gets Installed With a New Central AC

The outdoor condenser unit sits on a concrete 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 mounts in a utility closet, basement, or attic and houses the evaporator coil along with the blower that moves conditioned air through the home.
A metering device, usually a small expansion valve or fixed orifice fitting, is installed where the refrigerant line enters the evaporator coil and controls how much refrigerant passes through. The thermostat goes on an interior wall and gives the homeowner the single control point for the whole system. Refrigerant lines run between the two main units, and a condensate drain line carries moisture away from the air handler.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the configuration of your house.

What HVAC Installation Looks Like in Franklin 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 Franklin 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 History in Franklin County
Alabama's climate puts real stress on cooling equipment, and Franklin County gets its share of the conditions that shorten equipment life and drive up demand. How often that happens here is a local fact, and it shapes what a well-matched central AC installation needs to handle.
