The compressor in a central AC unit takes the hardest hit from a long cooling season: every start cycle stresses the windings, and the contactor that triggers each start pits and burns with repeated switching. Homes in Mississippi County, AR run cooling about five months a year, from May through September. A contractor diagnosing a failed compressor here checks how many of those cycles the unit has logged, whether the contactor is pitted past its service limit, and whether the capacitor that helps the motor start is still holding its rating. A unit that has run through summers like these without a capacitor check or contactor replacement often fails at the compressor, which is the expensive end of the repair.
Ductwork laid into a house generations back and never replaced accumulates the same wear a compressor does, but it rarely gets looked at until a repair call forces the issue. Half the homes in Mississippi County, Arkansas were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor opening a unit in stock this old routinely finds that the sealed sections of duct have lost their integrity, that insulation has separated, and that what looked like an equipment problem is partly a distribution problem. Parts for the equipment are findable; duct failures found mid-repair are a second conversation the homeowner did not expect to have.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, the two components a contractor reaches for first when the system stops cooling. The compressor is the heart of the refrigerant circuit, and a failed one is often what turns a repair call into a longer conversation. The condenser coil sheds heat to the outside air, and a damaged or dirty coil shows up fast in cooling performance.
Inside the house, the air handler holds the evaporator coil and the blower that pulls air across it. The evaporator coil is where refrigerant absorbs heat from indoor air, and a leak or freeze here is a common finding. The expansion valve, the refrigerant lines running between the two units, and the capacitors and contactors inside both cabinets round out what a contractor works through on a diagnostic call.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Mississippi County
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.
