Sizing a central AC system for a West Feliciana Parish home starts with what the compressor is actually being asked to carry each year. Homes in West Feliciana Parish, LA run cooling about five months a year, from May through September. The compressor, the condenser fan, and the contactor all cycle through that full stretch, and a system that was sized too small or commissioned without a proper load calculation accumulates wear on those parts faster than one that was matched to the house. A contractor quoting a new installation here factors that workload into equipment selection before anything else gets priced.
Ductwork laid down for an earlier generation of equipment carries a real question into any central AC installation: will it move air the way a new system needs, or will a contractor have to rework sections before the unit can do its job? Half the homes in West Feliciana Parish, Louisiana were built in 1991 or earlier (2020-2024 ACS 5-year). That spread of older stock means the duct layout a contractor finds on arrival is as consequential as the equipment being quoted. Electrical service matters too, since panels sized for lighter loads may need an upgrade before a new unit can run. The equipment choice comes after those answers, not before.
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 hardware that drives the whole system. Inside, the air handler mounts in a closet, attic, or utility space and contains the evaporator coil and blower that move conditioned air into the living space.
A copper refrigerant line set runs between the two units, connecting the outdoor and indoor sides of the system. The thermostat goes on an interior wall where it reads the air temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What HVAC Installation Looks Like in West Feliciana Parish
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.
