A contractor diagnosing central AC in Grant County has to account for what the equipment has already been through before settling on a cause. 135 severe weather events were recorded in Grant County, West Virginia between 2015 and 2024. At that rate, components that handle electrical and thermal load, particularly capacitors and contactors, wear faster than a calendar-based estimate would suggest. A system that looks old enough to fail on age alone may actually have a stress-related failure in a part that costs a fraction of a full replacement. That distinction changes what a contractor quotes first.
Ductwork in a house this old has already outlasted whatever it was first built around, and the central AC running in it now is not the system that came with the house. Half the homes in Grant County, West Virginia were built in 1980 or earlier (2020-2024 ACS 5-year). When a repair call comes in, what shapes the job is what the opened unit turns out to take: whether the capacitors, contactors, or refrigerant fittings a system of that vintage requires are still in active supply or have moved to special order. That gap between what the parts list says and what a distributor can ship same-week is where repair scopes get complicated, and it is specific to stock of this age.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which are the pieces a contractor goes to first when a system stops cooling. The compressor is the heart of the refrigerant circuit, and a failed one is a common reason a system runs but puts out no cold air. The condenser coil wraps around the outside of that cabinet and sheds heat to the open air.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower, usually in a basement, closet, or utility room. The evaporator coil is where refrigerant does its work, and a frozen coil or a refrigerant leak shows up here. The blower motor pulls air across that coil and pushes it through the house, and a failing motor is often behind weak or uneven airflow.
The drawing shows a typical layout, and a licensed contractor will determine which parts apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Grant 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.
