A contractor sizing a central AC system in Bienville Parish has to get the load calculation right, because the compressor does not get much rest. Homes in Bienville Parish, LA run cooling about five months a year, from May through September. Contactor wear, refrigerant stress, and condenser fan fatigue all build across those months, and an undersized or poorly installed system will show those problems sooner than the same equipment might elsewhere. The quality of the initial installation sets how well the equipment holds up under that accumulated load.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow and load that a new central AC system will not match without adjustment. Half the homes in Bienville Parish, Louisiana were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in stock like this has to assess what is already in the walls and attic before the equipment question is even relevant: whether the existing duct network can move the volume a modern unit delivers, and whether the electrical service will carry what that unit draws. Those two things, not the equipment itself, are where the job gets priced and where it gets complicated.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the condenser coil, the two components that do the heaviest work in the system. Inside the home, the air handler mounts in a utility closet, attic, or basement and pulls return air across the evaporator coil before pushing conditioned air back through the house.
The refrigerant lines run between the outdoor unit and the air handler, connecting the two halves of the system through the wall or floor. A thermostat goes on an interior wall and gives the homeowner control over the whole setup, while a condensate drain line carries moisture away from the evaporator coil to a floor drain or outdoors.
The drawing shows how these pieces fit together in a typical layout, and a licensed contractor determines what the installation looks like in your specific home.

What Happens on Install Day in Bienville 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.
