A contractor quoting a central AC installation in Bullock County has to work out what the house actually needs, and the local weather record is a smaller part of that calculation than in many Alabama counties. 36 severe weather events were recorded in Bullock County, Alabama between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and the equipment a homeowner is replacing has most likely worn out from age, undersizing, or poor original installation rather than from repeated storm stress. That shifts what a licensed contractor focuses on: load calculations, duct condition, and whether the new system is matched to the structure rather than specced to withstand weather it rarely faces.
Ductwork laid down for an older system carries assumptions about airflow, return placement, and trunk sizing that often do not match what a modern central AC unit needs to move air efficiently through the house. Half the homes in Bullock County, Alabama were built in 1987 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what a contractor is now asked to put in it is where the real installation decision lives. A contractor measuring the existing duct runs has to judge whether they will carry the new system's load or require modification before a unit ever goes in. The electrical side gets the same look, since panel capacity and existing wiring routes in housing of this vintage were not laid out with today's equipment in mind.
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 shed heat to the outside air. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and blower that pull warm air from the home and push cooled air back through the ducts.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through the wall or floor. The thermostat goes on an interior wall and gives the homeowner control over when the system runs and at what setpoint.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.

What happens on installation day in Bullock 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 Bullock 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 Bullock County
Alabama's climate puts real pressure on cooling equipment, and Bullock County gets its share of that pressure through storm activity that stresses systems before and after installation. How much a central AC unit is asked to do depends partly on local conditions, which is why weather history belongs on a page about the work.
