The compressor and condenser fan in a central AC unit here start and stop through a long summer stretch, and the contactor that switches the compressor on takes every one of those cycles as mechanical stress. Homes in Itawamba County, MS run cooling about five months a year, from May through September. A contractor quoting a repair has to treat that accumulated runtime as the baseline condition of the equipment, because a system that has been running hard through that kind of load will show wear on the cycling components first. Refrigerant capacity, contactor pitting, and condenser fan motor bearings are where the work tends to surface.
Ductwork in a house that has been sealed, patched, and lived in for this long carries its own record. Half the homes in Itawamba County, Mississippi were built in 1984 or earlier (2020-2024 ACS 5-year). When a system breaks down and a contractor opens it up, the question of whether a given part is still in production matters, but what the duct runs look like matters just as much to the repair scope. Gaps, compression, and years of sediment change what gets replaced and what gets cleaned out before the system can run the way the repair is supposed to make it run.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil. These are the pieces a contractor goes to first when the system runs but produces no cold air or trips a breaker. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor each shows up here.
Inside the house, the air handler holds the evaporator coil and the blower motor. The evaporator coil is where the system pulls heat from indoor air, so a frozen coil or a refrigerant shortage points back to this component. The blower motor is what moves air across it and through the home.
The drawing shows the standard layout of these components, and a licensed contractor determines which ones apply to your specific house and system.

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.
