Takes about a minute. No obligation.
The compressor in a Clark County home starts and stops through a long stretch of warm months, and the parts that wear under that cycling are the contactor, the condenser fan motor, and the capacitor that kicks the compressor into each new run. Homes in Clark County, AR run cooling about five months a year, from May through September. Contractors diagnosing a failed or underperforming system here check those components before anything else, because that is where accumulated starts show up first. A refrigerant leak that has been slow all season will also surface when the system is pushed hardest, which is exactly when the call comes in.
Ductwork in the older half of Clark County's housing stock was sized and routed for systems that are no longer in those houses, and what that ductwork has accumulated since is a separate question from whatever the central AC unit itself shows. Half the homes in Clark County, Arkansas were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor opening a failed unit will price out parts against what that model still has in supply, but the repair scope can widen once they trace the airflow back through ducts that have been carrying a mismatch load through Arkansas summers for a long time. Restricted or leaking ductwork changes the diagnosis, and changes the bill.
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 carries the compressor and condenser coil. Those two components draw the most attention during a repair call. When the system runs but does not cool, or does not run at all, the compressor and the coil are where a contractor starts.
Inside the house, the air handler holds the evaporator coil and the blower. The air handler is typically in a utility closet, an attic, or a basement, and it works in tandem with the outdoor unit. The expansion valve and the refrigerant lines that connect the two sides of the system are also on the checklist, since a fault anywhere along that path will affect the whole system.
The drawing shows a general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

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.
