A contractor quoting a central AC replacement in Concordia Parish has to size the system for what the compressor is actually asked to do here, not for what a manufacturer's default suggests. Homes in Concordia Parish, LA run cooling about five months a year, from May through September. That workload falls on the same components every cycle: the compressor starts and stops, the condenser fan pulls heat out, and the contactor closes each time the thermostat calls. An undersized unit or a poorly sealed duct system loses efficiency incrementally across every one of those cycles, and the compressor shows the damage well before the homeowner notices comfort problems.
Ductwork laid out for one generation of equipment does not automatically carry the next. Half the homes in Concordia Parish, Louisiana were built in 1977 or earlier (2020-2024 ACS 5-year). That spread in the housing stock means a contractor opening up an attic or a crawlspace in Concordia Parish is frequently working around duct runs that were never sized for the static pressure a modern central AC system pushes. The electrical service behind the panel is the same story. What a new unit actually draws and what the existing wiring was built to handle are two separate questions, and a quote that skips either one is incomplete before it leaves the page.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, the hardware that does the heaviest work in the system. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and circulates air across the evaporator coil, which is the indoor coil that pulls heat from the air.
A copper refrigerant line set runs between the two units, connecting the outdoor pad to the indoor cabinet and completing the circuit between them. The thermostat mounts on an interior wall and is the control point a homeowner will actually touch, telling the system when to run and when to stop.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this 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.
