A contractor sizing and installing central AC in Butler County has to account for what the local weather actually demands, and that picture is less punishing than it might seem. 57 severe weather events were recorded in Butler County, Alabama between 2015 and 2024. At that rate, severe weather is something equipment here encounters now and then, not a chronic operating pressure. A system that was correctly sized for this climate, properly sealed, and set up with adequate refrigerant charge on day one is not fighting an unusually hostile environment. When an install goes wrong in Butler County, the cause is almost always in the decisions made on the day of the job.
Ductwork laid decades before current central AC systems were designed may move air the wrong way, through the wrong sizes, or along routes that made sense for equipment no longer made. Half the homes in Butler County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor installing a new central AC unit here sizes the system to the house, but the ductwork determines whether that sizing holds once the equipment runs. If the existing duct layout cannot carry the load the new unit delivers, the installation scope grows before the equipment question is settled.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and the condenser coil. The indoor air handler mounts inside, most often in a utility closet, attic, or basement, and holds the evaporator coil and the blower that moves air through the home.
The thermostat goes on an interior wall where it reads the temperature of the living space and signals the system when to run. A condensate drain line runs from the air handler to a floor drain or outside, carrying away the moisture the evaporator coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines what fits the configuration of your specific house.

What HVAC Installation Looks Like in Butler 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 Butler 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 Butler County
