Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops thousands of times across a cooling season, and the contactor and condenser fan take that same load. Homes in Yazoo County, MS run cooling about five months a year, from May through September. By the time a system needs repair, those parts have absorbed years of hard cycling, and a contractor will check the compressor draw and the contactor contacts before tracing a fault anywhere else. Refrigerant charge and coil condition follow. A system that has been running short on charge for even one full season shows it in the compressor windings.
Parts availability is the variable that most often reshapes a repair quote here. Half the homes in Yazoo County, Mississippi were built in 1982 or earlier (2020-2024 ACS 5-year). A house that old has seen its original equipment replaced at least once, and whatever is running now has been running long enough that a contractor opening a failed unit has to confirm whether the parts it takes are still in production before a repair scope can be set. If they are not, the job changes.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a pad outside the house and is where heat pulled from inside gets released. It holds the compressor and the condenser coil, and when the system stops cooling or starts making noise, those two components are where a contractor looks first. The compressor in particular is the workhorse of the whole system.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a common source of problems when it ices over or leaks refrigerant, and the blower motor gets checked when airflow is weak or uneven. The refrigerant lines running between the two units and the thermostat on the wall round out what a contractor traces when diagnosing a fault.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

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.
