A contractor diagnosing a failed central AC unit in Fulton County has to decide what actually wore the system down. 53 severe weather events were recorded in Fulton County, Indiana between 2015 and 2024. At that rate, severe weather touches equipment here, but not often enough to be the default explanation for a compressor that quit or a coil that is leaking. What a contractor finds instead, again and again, is a system that ran too long without a filter change, or a refrigerant charge that drifted over years, or a condenser fan motor that simply reached the end of its service life. The weather record belongs in the picture, but age and maintenance history carry more weight in this county.
Ductwork in a house this old has seen replacement equipment come through at least once, and the system running now reflects decisions made years after the original build. Half the homes in Fulton County, Indiana were built in 1966 or earlier (2020-2024 ACS 5-year). What that means for repair work is specific: once a contractor opens the unit, the question is whether the components it takes are still in production. Older equipment often runs on parts whose supply has narrowed, and a repair that looks straightforward from the outside can stall on that single problem. A contractor working here prices the parts before promising the fix.
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 holds the compressor and condenser coil. These are the pieces a contractor looks at early. When the system runs but produces little cooling, or makes a hard noise on startup, the compressor and the coil around it are the first suspects.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil sits directly above the heat exchanger or on top of the furnace, and when it ices over or leaks refrigerant, the whole system stops moving cool air. The blower pushes conditioned air into the ducts, and a failed motor there means rooms get nothing.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts apply to your particular house and setup.

What Happens When the Contractor Comes Out
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 Fulton County
Extreme weather puts real strain on central AC systems, from hard cycling during heat spikes to pressure on components after storms pass through. Repair demand in Fulton County follows the weather, which is why local conditions are part of the picture for any homeowner weighing their options.
