A compressor or capacitor that has given out in Giles County probably did not fail because the weather pushed it past its limits. 71 severe weather events were recorded in Giles County, Tennessee between 2015 and 2024. At that rate, severe weather is an event in this county rather than a steady operating condition, and a contractor working a repair here will look first at the age of the unit, the state of the refrigerant charge, and whether the system has been serviced. Worn contactor points and clogged coils cause more failures in this area than storm load does.
Ductwork laid in for one generation of equipment and pressed into service for another is where a central AC repair in Giles County gets complicated. Half the homes in Giles County, Tennessee were built in 1982 or earlier (2020-2024 ACS 5-year). A system that has been retrofitted into older duct runs produces symptoms that point back to the ducts as much as to the equipment itself, and a contractor diagnosing a refrigerant or airflow fault has to account for that. Restricted or undersized runs can load a compressor in ways that mimic component failure. The repair the homeowner expects and the repair the opened system requires are often two different jobs.
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 the condenser coil. Both are common starting points when a system stops cooling. The air handler or furnace blower lives inside, typically in a closet, attic, or basement, and it pushes conditioned air through the house.
The evaporator coil sits directly above or below the air handler and is where the cooling happens. The refrigerant lines run between the indoor and outdoor units, and the expansion valve and refrigerant charge itself are checked alongside them. The thermostat, mounted on a wall inside the living space, is where a contractor often starts because a wiring or calibration fault there can mimic a much larger problem.
The drawing shows a typical layout, and a licensed contractor determines which components apply to this particular home.

What the repair visit looks like
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 Giles County
Storm activity puts stress on cooling equipment: power surges, sudden shutdowns, and extended high-demand runs all accelerate wear. How much of that your system has absorbed depends on what the weather here has actually done.
