Homes in Pemiscot County, MO run cooling about five months a year, from May through September. A compressor that starts and stops across that many cooling cycles accumulates wear on the contactor, the capacitor, and the condenser fan motor at a pace a short-season system never reaches. When a central AC unit in this county fails, a contractor looks hard at those cycling components first. A unit that has run faithfully for years may show a contactor burned down to bare copper or a capacitor that can no longer hold a charge under load.
Half the homes in Pemiscot County, Missouri were built in 1973 or earlier (2020-2024 ACS 5-year). A central AC unit running in a house that old is probably on its second or third refrigerant-compatible component, and the parts a contractor needs when something fails are not always still made. What the opened system contains matters more than what the permit says the house is: a condenser board or metering device specced for a discontinued refrigerant type sends the repair in a different direction than a current-production system would, and the contractor has to source accordingly. The ductwork in houses of this vintage was sized for whatever was running then, which shapes what the system can actually deliver once it is repaired.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets shed to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor looks at when the system stops cooling. A failed compressor, a refrigerant leak at the coil inside that cabinet, or a dead condenser fan motor each show up as the same symptom to the homeowner: warm air.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, the blower motor, and the filter. The evaporator coil pulls heat out of the indoor air, so a frozen coil or a refrigerant shortage here is a common source of trouble. The thermostat on the wall ties the whole system together and is often the first thing a contractor checks before touching anything else.
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 Arrives
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.
Severe Weather Events in Pemiscot County
Extreme weather puts real strain on central AC systems, and that strain accumulates over time into worn components and repair calls. How much weather a county sees shapes how hard the equipment works, which makes local history a practical input for anyone thinking about repair.
