A contractor quoting a central AC repair in Scott County has to sort out what actually drove the failure before anything else can be priced. 72 severe weather events were recorded in Scott County, Tennessee between 2015 and 2024. At roughly that rate, severe weather lands as an event, not a standing condition the equipment fights through every season. A compressor that fails here has most likely worn out, been underserviced, or been running against a poorly sized or poorly installed original job. That is where a contractor looks first, and that is what the diagnosis has to answer before parts get ordered.
Half the homes in Scott County, Tennessee were built in 1988 or earlier (2020-2024 ACS 5-year). The systems that went into houses built around that time have been running long enough that standard compressor and capacitor lines have been discontinued, revised, or consolidated by manufacturers. When a contractor opens a unit and finds a failed component, the repair turns on whether a matching part still exists in the supply chain, and that question has a different answer for a system of this vintage than for one installed recently. A refrigerant line or a control board can stall a job that looked straightforward from the outside.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and houses the compressor and condenser coil. These are the parts a contractor looks at first when a system stops cooling. The compressor is the most common source of a hard failure, and a damaged condenser coil often shows up as ice on the lines or warm air at the vents.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower moves that air through the house. A clogged coil, a failing blower motor, or a refrigerant leak between the two units can each produce the same symptom, which is why a contractor traces the problem through both ends before deciding where the repair sits.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific equipment and configuration in your 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.
