Takes about a minute. No obligation.
A contractor sent out for a central AC repair in Greene County is working through a system that has spent years running against real but infrequent stress. 39 severe weather events were recorded in Greene County, Alabama between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a grinding background condition, so a compressor failure or a refrigerant problem almost always traces back to something else: how old the unit is, how well it was installed, and how consistently it was serviced. A contractor here inspects those factors first because that is where the answers are.
Ductwork laid down for an earlier generation of equipment carries the marks of every repair and retrofit since. Half the homes in Greene County, Alabama were built in 1981 or earlier (2020-2024 ACS 5-year). That history matters when a central AC system needs work, because what a contractor finds once the unit is open may be a system whose refrigerant lines, drain paths, or internal components belong to a specification that has since been discontinued. Parts availability for equipment installed into stock this old is the question that shapes the repair bill, and a contractor has to confirm what is actually inside before any estimate holds.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it is where heat gets pushed out of the home. The indoor air handler or furnace sits inside, often in a closet, attic, or basement, and it moves air across the evaporator coil. That coil is the piece a contractor reaches for early when cooling has dropped off or stopped.
The refrigerant lines run between the two units, carrying the working fluid that the whole system depends on, and a leak anywhere along them will show up as a performance problem that originates somewhere else. The thermostat on the wall is the control point, and a faulty one can mimic symptoms that look like a compressor or coil failure.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

What HVAC Repair Looks Like in Greene 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.
