A central AC system in this area gets sized against what the climate actually demands, and that is a local calculation a contractor works out before anything else. 95 severe weather events were recorded in Escambia County, Alabama between 2015 and 2024. At roughly that rate, severe weather is a standing feature of life for any system running here, not an occasional interruption to it. A contractor choosing equipment for a new install in this county has to factor in accumulated stress on components from the start, which means the unit selected and the way it is installed both carry more weight than they would somewhere the climate runs quieter.
Ductwork sized and routed for older equipment sits inside a large share of homes here. Half the homes in Escambia County, Alabama were built in 1983 or earlier (2020-2024 ACS 5-year). What that means for installation is that a contractor pulling out an old unit and pricing the replacement has to assess what the existing duct system will actually do with a modern load before settling on equipment size or placement. Sealing, resizing, or rerouting sections of ductwork is often where the real scope of a central AC job is decided, and the electrical service gets the same look before any equipment is specified.
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, which are the mechanical heart of the system. Inside, the air handler or furnace cabinet stands in a utility room, basement, or attic and contains the evaporator coil and blower that push conditioned air through the house.
The refrigerant lines run between the two units, connecting the indoor and outdoor sides of the system. A thermostat goes on an interior wall where it reads the air temperature and signals the system to run. The condensate drain line carries moisture pulled from the indoor air out of the house.
The drawing shows how these pieces relate in a typical layout, and a licensed contractor determines exactly how the system comes together in your home.

What the installation looks like
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.

Severe Weather Events in Escambia County
Weather puts load on cooling equipment, and local conditions shape how hard a system has to work over its lifetime. That makes the climate record here a practical input for any central AC installation decision.
