A contractor called out to repair a central AC system in Okaloosa County has to settle one question before anything else: how much of what they are looking at is weather wear and how much is age or installation. 109 severe weather events were recorded in Okaloosa County, Florida between 2015 and 2024. At that rate, stress on electrical components, refrigerant lines, and capacitors accumulates between service calls, and a contractor who skips that accounting risks replacing a part that will fail again for the same reason. The diagnosis shapes the repair scope.
Ductwork and wiring in a house get installed once and stay. Half the homes in Okaloosa County, Florida were built in 1990 or earlier (2020-2024 ACS 5-year). That means a substantial share of the county's central AC systems have been running long enough that the parts they require sit at the edge of what manufacturers still stock. When a technician opens a failed unit, the repair cost and the repair timeline often turn on whether those parts are still in the supply chain, and for equipment of this vintage, that is a real question a contractor has to answer before they can tell you what the job will run.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil. These are where a contractor starts when the system stops cooling, runs but does nothing, or makes sounds it should not. The indoor air handler or furnace cabinet, tucked in a closet, attic, or utility room, holds the evaporator coil and the blower that moves air across it.
The refrigerant lines run between those two cabinets, and the expansion valve sits along that path controlling how refrigerant flows into the evaporator coil. The thermostat on the wall is the system's control point, and a fault there can look like a failure anywhere else in the system.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to your specific home and what condition each one is in.

What HVAC Repair Looks Like in Okaloosa 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.
