Takes about a minute. No obligation.
A contractor quoting a central AC install in East Feliciana Parish has to get the load calculation right before anything else. Homes in East Feliciana Parish, LA run cooling about five months a year, from May through September. The compressor, the condenser fan, and the contactor all accumulate wear through every start-stop cycle across those months, and a system that is undersized runs longer cycles to hit setpoint, which drives wear faster. Picking equipment by price or brand before a proper Manual J is done leaves that stress built into the install from day one.
Ductwork sized for the equipment that came with the house does not automatically carry what a contractor brings to replace it. Half the homes in East Feliciana Parish, Louisiana were built in 1989 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were built for and what a new central AC system needs is where installation jobs in this parish get complicated or repriced. A contractor opening up an older system here checks whether the existing runs can handle the airflow a modern unit delivers before the new equipment goes in. If they cannot, the duct work is part of the job, and so is the electrical service panel.
What Gets Installed With a New Central AC
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and blower fan. These two cabinets are the core of what a contractor brings to the job.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through an exterior wall. The thermostat goes on an interior wall in the living space and is the control point for the whole system. A condensate drain line also runs from the air handler to a floor drain or outdoors to carry away moisture.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits into your particular house.

What the Installation Actually 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.
