Takes about a minute. No obligation.
A contractor diagnosing a central AC system in Ouachita Parish starts with the compressor and the contactor, and there is a straightforward reason for that. Homes in Ouachita Parish, LA run cooling about five months a year, from May through September. A compressor that starts and stops through a run that long accumulates wear on its windings, its valve seats, and the contactor points that switch it on. By the time a homeowner calls for a repair, those parts have already been through heavy cycling seasons and the failure usually traces back to them. Refrigerant leaks and coil problems get checked, but the compressor is where the work tends to land.
Refrigerant type, capacitors, contactors, and control boards tell a contractor more about how a repair goes than the house around the unit does. Half the homes in Ouachita Parish, Louisiana were built in 1983 or earlier (2020-2024 ACS 5-year). A house built that long ago has almost certainly had its original system replaced at least once, so the equipment a contractor opens is not the equipment the house was designed around. What matters is whether the parts that system actually takes are still manufactured and what condition the coil and compressor are in once the panel comes off.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, which are where most mechanical failures show up first. Inside, the air handler or furnace cabinet contains the evaporator coil and blower fan, mounted in a closet, attic, or utility room depending on the house.
The refrigerant lines run between the two units, and a contractor checks them for leaks or pressure loss when neither obvious piece is the source of the problem. The thermostat and the system's electrical components, including capacitors and contactors in the outdoor unit, round out what gets examined during a repair call.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what work is needed in your specific home.

What Happens When the Contractor Shows Up
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.
