A contractor quoting central AC installation in Pike County works out the sizing from the structure and the local climate, not from a parts list. 66 severe weather events were recorded in Pike County, Alabama between 2015 and 2024. At that rate, severe weather is an event here rather than a persistent operating condition, which means a system that has been running poorly was almost certainly undersized or installed with shortcuts rather than worn down by weather load. Duct layout, refrigerant line routing, and the quality of the electrical connections at the disconnect all carry more weight in this county than storm history does.
Ductwork in a house does not get replaced on a schedule the way equipment does, which means a central AC installation here turns heavily on what the existing duct network can actually carry. Half the homes in Pike County, Alabama were built in 1986 or earlier (2020-2024 ACS 5-year). That puts the ductwork, and the electrical service feeding the air handler, at the front of what a contractor has to evaluate before the new equipment is quoted. A duct system laid in for one generation of air conditioning may not move air the way a current unit expects. If it does not, the installation job is larger than a straight equipment swap.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and houses the compressor and condenser coil. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and holds the evaporator coil that works alongside it. These two units are the core of what a contractor brings to the job.
A refrigerant line set runs between the indoor and outdoor units, carrying the refrigerant that lets both coils do their work. The thermostat mounts on an interior wall where it reads the air temperature and tells the system when to run. A condensate drain line also runs from the air handler to a floor drain or outside, carrying off the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What the installation looks like in Pike 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 Pike 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.
