Takes about a minute. No obligation.
A repair contractor working a central AC unit in Iberia Parish starts at the compressor and the condenser fan, because those are the components that have been cycling hard since spring and will keep running through October. Homes in Iberia Parish, LA run cooling about six months a year, from May through October. The contactor that switches the compressor on and off takes a start-up surge every time the thermostat calls for cooling, and a long cooling season means that part has fired hundreds of times before a homeowner notices anything wrong. Worn contactors and weakened capacitors show up on a service call here more reliably than refrigerant leaks or coil failures do. A contractor who skips straight to the refrigerant charge without checking those electrical components first is quoting the wrong repair.
Ductwork and wiring that have outlasted multiple systems carry their own history, but for repair work the sharper question is what the opened unit actually contains. Half the homes in Iberia Parish, Louisiana were built in 1982 or earlier (2020-2024 ACS 5-year). A compressor or control board pulled from a system running in stock this old may take a part that suppliers have discontinued or carry as special order only. That gap between what the system needs and what a distributor has on a shelf is what sets the repair scope, and a contractor who skips opening the unit before quoting a price will get that scope wrong.
The Parts of a Central AC a Contractor Checks During a Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. These are common starting points in a repair call. The air handler or furnace cabinet lives inside, typically in a closet, attic, or utility room, and holds the evaporator coil and blower fan that move conditioned air through the home.
The refrigerant lines run between the two units, and a contractor checks them for leaks or damage when pressures are off. The thermostat on the wall is also part of what a contractor inspects, since a wiring fault or failed sensor there can mimic a much larger mechanical problem.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply to the specific system and setup in your house.

What HVAC Repair Looks Like in Iberia 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.
